Re: Boston Logan International Airport 2022 Environmental Status and Planning
Report ‐ EEA #3247
Dear Secretary Tepper and Director Kim:
On behalf of the Massachusetts Port Authority (Massport), we are pleased to submit this
2022 Environmental Status and Planning Report (ESPR) for Boston Logan International Airport (Logan
Airport or the Airport). This filing continues Massport’s four ‐ decade practice of providing an extensive
record of Logan Airport’s environmental trends, facility planning, operations and passenger data, and
Massport’s mitigation commitments. This ESPR focuses on current operational and environmental
conditions at the Airport and future conditions forecasted over the next 10 to 15 years.
The ESPR document is produced by Massport every five years, but ESPR publications are interspersed
with annual Environmental Data Reports (EDRs), which focus on year ‐ over ‐ year conditions and trends.
The Logan Airport ESPR is a unique document within the Massachusetts Environmental Policy Act
(MEPA) process, as Massport is the only state agency that prepares such a document. Notably, unlike
other MEPA filings, ESPRs and EDRs are not “projects” within the typical MEPA framework. These
documents do not replace individual project filings subject to MEPA, nor do they serve as approval for a
specific project or activity. Rather, the ESPR and EDR series are critical tools for Massport as they
provide current and historical context for evaluating individual projects at Logan Airport that meet state
and federal environmental review thresholds, as well as context for understanding the cumulative
environmental effects of Logan Airport’s operations and activities.
In 2022, Logan Airport continued to progress towards a recovery to pre ‐ pandemic passengers and
aircraft operations activity levels, but passenger activity still remained 15 percent less than 2019 levels
and aircraft operations were 11 percent less than 2019. Although long ‐ term recovery depends on
business and international travel returning, Logan Airport continues to be an integral part of the
regional transportation system, supporting connections to small regional airports in addition to
providing an essential link between rail, port, and ground transportation networks.
Logan Airport operations were adjusted or reduced by airlines and tenants in response to pandemic
impacts, which led to the temporary modification or deferment of several Airport projects and
programs. In 2022, Massport was able to restart several deferred projects and programs, and Massport
will continue to plan and prepare for the full recovery of aircraft operations and passenger activity.
Logan Airport is focusing on reducing emissions from its operations through fleet and ground service
equipment (GSE) conversion to electric or other renewable fuels and by promoting high ‐ occupancy
vehicle (HOV) use. Logan Airport continues to be a leading U.S. airport in promoting HOV usage. The

Secretary Rebecca Tepper Page 2 May 31, 2024
Airport has exceeded Massport’s targets for percent HOV mode share and remains on track to meet
future goals. Key initiatives implemented in 2022, or planned for the immediate future, to improve
ground access to the Airport include expanding Logan Express service, purchasing replacement
Massachusetts Bay Transportation Authority Silver Line buses, and continuing RideApp Management
Plan implementation.
Decreased operations in 2022, including reductions in nighttime operations and a shift towards newer,
quieter engine types, reduced the percentage of the population exposed to substantial Airport noise.
Efforts are also underway with the Federal Aviation Administration and Massachusetts Institute of
Technology to reduce noise by changing navigation procedures and flight performance modifications.
Massport also re ‐ initiated the residential sound insulation program for FAA eligible residences after the
FAA changed its qualification criteria for homes already insulated before 1993.
As part of its ongoing strategic planning efforts, Massport prepares future forecasts of aircraft
operations and passenger activity over a forecasting timeframe of the next 10 to 15 years for each ESPR,
which is referred to as the Future Planning Horizon. The 2022 ESPR evaluates operational and
environmental conditions associated with the anticipated 53.5 million annual air passengers and
495,000 annual aircraft operations projected to occur within the 2022 ESPR Future Planning Horizon,
which also aligns with the trends projected in the 2017 ESPR .
The Future Planning Horizon activity forecasts were used to analyze future air quality, ground access,
and noise conditions. Analysis results showed future noise, air emissions, and vehicular traffic density at
the Airport will increase in the future and likely exceed 2019 and 2022 conditions but will still remain
well below historic highs and well below EPA NAAQS standards for criteria pollutants. In addition,
planning initiatives such as roadway and garage facility enhancements, increased sound insulation, and
Massport’s Roadmap to Net Zero (Net Zero by 2031) in addition to existing mitigation strategies will
reduce adverse effects associated with over the Future Planning Horizon.
In response to new MEPA policies, stakeholder engagement, and ongoing coordination with MEPA, the
2022 ESPR includes the new Chapter 2, Sustainability, Outreach, and Environmental Justice , which
covers:
 Climate Adaptation and Resiliency – In 2022, Massport published its Roadmap to Net Zero by
2031 , an ambitious, Authority ‐ wide program to achieve net zero GHG emissions by 2031 for the
activities under Massport’s control. Chapter 2 discusses the Net Zero by 2031 program as well as
other sustainability and resiliency measures undertaken at Logan Airport that demonstrate
Massport’s commitment to being an environmental steward and leader in both the region and
aviation industry.
 Community Involvement and Environmental Initiatives – Massport strives to be a good
neighbor to the surrounding community through its development of parks and open space,
charitable giving and funding local foundations aimed at improving community quality of life.
Massport continues to develop initiatives to respond to cumulative environmental impacts from
Airport operations, separate from project ‐ specific mitigation commitments.

Secretary Rebecca Tepper Page 3 May 31, 2024
 Massport’s Outreach – Massport's Community Relations & Government Affairs Department
manages relationships with community members, local organizations, and government officials,
with a focus on engaging Environmental Justice (EJ) communities. For this and future reports,
Massport will expand EJ outreach through translation services for populations within a 5 ‐ mile
radius of Logan Airport and Massport Community Advisory Committee communities.
 Environmental Justice and Public Health – Located in an urban center, Massport recognizes
Logan Airport is proximal to EJ communities. Massport has conducted an existing conditions
review in this ESPR to characterize EJ block groups and public health within 1 ‐ mile of the Airport.
ESPR Content and Structure
The 2022 ESPR responds to the Secretary’s Certificate on the Boston Logan International Airport
2020/2021 EDR , dated January 2023. The ESPR provides updated conditions for the following topics:
 Passenger levels, aircraft operations, aircraft fleets, and cargo volumes;
 Planning, design, and construction activities at Logan Airport;
 Sustainability initiatives;
 Regional transportation statistics and initiatives;
 Key environmental indicators, including ground access, noise, air quality and GHG emissions,
and water quality; and
 Status of Logan Airport project mitigation
The 2022 ESPR includes the Secretary’s Certificate on the Boston Logan International Airport 2020/2021
EDR and associated comment letters. Certificates received on the Logan Airport Parking Project
(EEA# 15665) and Terminal E Modernization Project (EEA# 15434), which included items to be addressed
in future EDRs and ESPRs, are also provided. Supporting technical appendices are available
electronically.
In response to comments on the 2020/2021 EDR , we have reevaluated the contents of chapters to
streamline the narrative to focus on 2022 updates on existing initiatives, new programs and planning,
and future forecast outcomes. In addition, the document has been made more accessible through an
added glossary, improved navigation, and bookmarking within the electronic version.

becoming commonly known as the Clean Water Act. This U.S.
federal law, regulated by the U.S. Environmental Protection
Agency (U.S. EPA), controls the discharge of pollutants into the
nation's surface waters, including lakes, rivers, streams, wetlands,
and coastal areas. The CWA established the basic structure for
regulating pollutant discharges into the waters of the United
States and gave the EPA the authority to implement pollution
control programs such as setting wastewater standards for
industry and the NPDES permit program.

Effective Perceived Noise Level (EPNL) A metric calculated by using a series of "tone corrected" perceived
noise levels, measured in EPNdB. This includes a "pure tone"
correction of up to 6 dB. EPNdB is an international standard for
aircraft noise certification and contributes to the calculation of
Logan Airport CNI.
Effective Runway Use vs. Actual Runway Use The Actual Runway Use is reported as annual percentages
calculated from operations counts that occurred on each runway.
In contrast, the Effective Runway Use calculation multiplies
nighttime operations by 10 before determining percentages.

Term (Acronym) Definition
Massachusetts Environmental Policy Act (MEPA) A state law that requires all state agencies to study the
environmental impacts of their projects before they are approved.
The MEPA review process typically begins with the submission of
an Environmental Notification Form (ENF) to the MEPA office,
which provides a preliminary description of the project and its
potential environmental impacts. If the project is deemed to have
significant environmental impacts, the proponent must then
prepare an Environmental Impact Report (EIR) that provides a
more detailed analysis. The Secretary of Energy and Environmental
Affairs (EEA) then issues a Secretary's Certificate, which determines
whether the EIR adequately and properly complies with MEPA and
whether any further steps are required. The EDR/ESPR evolved
from a Generic EIR (GEIR) to a comprehensive planning document
subject to MEPA review, including a Secretary’s Certificate for the
next iteration.
MEPA Review MEPA review is required if there it has jurisdiction over the project
and the project meets or exceeds a MEPA review threshold
(outlined at 301 CMR 11.03). MEPA review is not a permitting
process. MEPA requires public study, disclosure, and development
of feasible mitigation for a proposed project . It does not pass
judgement on whether a project is environmentally beneficial, or
whether a project can or should receive a particular permit. Those
decisions are left to the permitting agencies. MEPA review occurs

1.1. 1 Activity Levels
This 2022 ESPR reports on changes due to the COVID-19 pandemic at Logan Airport and within the
aviation industry. In 2022, passengers totaled over 36 million with 378,613 flight operations. At the end of
2022, total flight operations and passengers were 15 percent less than 2019 levels before COVID-19.
Long-term recovery at Logan Airport will depend largely on business and international travel as domestic
travel across the U.S. has almost fully returned to pre-COVID activity levels.
In 2020 and 2021, the pandemic caused a significant reduction in Airport activity and revenues, which
drove Massport, airlines, and other tenants to adjust and scale back their operations. Consequently,
several Airport projects and programs were temporarily deferred until conditions normalized. Chapter 4,
Airport Planning , provides project updates through December 2022, and includes projects moving forward
in 2023. Future Environmental Data Reports (EDRs) and ESPRs will continue to provide updates, as
available. Massport is continuously evaluating and planning for the full recovery of aircraft operations
and air passenger activity and remains committed to implementing a broad range of environmental and
operational measures designed to reduce impacts associated with Airport operations.
1.1. 2 Future Planning Horizon
As part of its on-going strategic planning efforts, Massport routinely prepares future forecasts for aircraft
operations and passenger activity levels. This 2022 ESPR evaluates future operational and environmental
conditions associated with the anticipated 53.5 million annual air passengers and 495,000 annual aircraft
operations projected to occur over the next 10 to 15 years, which is the forecasting timeframe referred to
as the Future Planning Horizon . Massport’s forecast methodology is consistent with the Federal Aviation
Administration’s (FAA’s) Terminal Area Forecast (TAF) . More information on the FAA’s TAF is available in
Chapter 3, Activity Levels and Forecasting , Section 3.5 .
1.1. 3 Massport Investment in Logan Airport
Massport continues to enhance Logan Airport’s safety, security, operational efficiency, and accessibility
while monitoring the environmental effects of its activities. Recent and on-going terminal area projects
aim to provide seamless post-security connectivity between the terminals and improve passengers’ travel
experience through consolidated security checkpoint areas. Massport also prioritizes access to and around
Logan Airport and works with the FAA to enhance airside safety by improving the Runway Safety
Area (RSA) and simplifying airfield geometry. 1
In addition, Massport has made a net zero greenhouse gas emissions (GHG) commitment for 2031, the
Roadmap to Net Zero by 2031 (Net Zero by 2031). More on Massport’s net zero programming efforts are
included in Chapter 2, Sustainability, Outreach, and Environmental Justice, Section 2.1.1.
1 Airfield geometry refers to the dimensions, orientation, condition, and number of runways on an airport’s campus.

Introduction and Executive Summary 1-5
Boston Logan International Airport 2022 ESPR 1
In response to the COVID-19 pandemic, Massport temporarily adjusted services to match shifting
passenger demand and to better manage environmental and operational impacts. However, Massport
remains committed to implementing project-related mitigation strategies, as documented in Chapter 10,
Project Mitigation.
1.2 ESPR and EDR Purpose
The 2022 ESPR is part of an annual series of environmental review
documents Massport submits to the Secretary of the Executive
Office of Energy and Environmental Affairs (EEA) , in accordance
with the Massachusetts Environmental Policy Act (MEPA) . 2 The
2022 ESPR continues Massport's established state-level environmental
review process, which assesses the cumulative environmental impacts
of activities associated with Logan Airport. These documents provide
the current and historical context for individual projects at Logan
Airport that meet state and federal environmental review thresholds
as well as the cumulative environmental effects of Logan Airport’s
operations and activities. Massport has published these documents
since 1979, making it a national leader in environmental reporting.
Approximately every five years, Massport prepares an ESPR to provide
a historical and prospective view of Logan Airport’s activities. For the
years between ESPRs, Massport prepares EDRs annually. This 2022
ESPR follows the 2020/2021 EDR , and reports on 2022 activities and
anticipated future conditions over the Future Planning Horizon.
Following the EEA's review of the 2020/2021 EDR , Massport was
directed to prepare this 2022 ESPR according to a scope established
by the Secretary's Certificate on the 2020/2021 EDR dated January 30,
2023. The Certificate is included in Appendix A, MEPA Certificates and
Responses to Comments . This ESPR fulfills the requirements outlined in
the Secretary’s Certificate on the 2020/2021 EDR and responds to the comments within the Secretary’s
Certificate and as well as those submitted by other commenters. This report also presents historical data
on the environmental conditions at Logan Airport dating back to 1990, where available, and includes
updates through December 31, 2022. A Spanish translation of this chapter is included after the English
version of the Executive Summary. Translations of the Executive Summary into Haitian Creole, Simplified
Chinese, and Portuguese are available at libraries noted in Appendix D, Distribution List and on Massport’s
website https://www.massport.com/environment/project-environmental-filings/boston-logan. To request

1.2.1 Historical Context for the Logan Airport EDR and ESPR Reporting
Process
Figure 1-3 shows the historical annual environmental reporting for Logan Airport, starting in 1979. These
documents initially reported on the current environmental conditions and future forecasts at the Airport
to the EEA and the public annually through the issuance of Generic Environmental Impact Reports (GEIR)
every five years, and Annual Updates in the interim years. In the early 2000s, in response to guidance from
EEA, these documents transitioned into an ESPR issued every five years with interim annual updates
provided as EDRs. Over time, these reports have evolved into an effective planning tool for Massport,
providing projections of environmental conditions to evaluate the overall effects of individual projects.

Introduction and Executive Summary 1-7
Boston Logan International Airport 2022 ESPR 1
1.2.2 Project-Specific Reviews
Massport’s ESPR is a unique document within the MEPA process. Unlike other MEPA documents, ESPRs
and the annual EDRs are not “projects” within the typical MEPA framework. The documents do not take
the place of any individual project filings subject to MEPA, nor do they serve as approval for any specific
activity. Rather, as their titles indicate, the ESPRs and EDRs report on Logan Airport’s general operating
and environmental conditions.
Airport projects undergo a project-specific, public environmental review
process when state environmental review thresholds are met. When
required pursuant to MEPA, Massport and Airport tenants submit
Environmental Notification Forms (ENFs) and Environmental Impact
Reports (EIRs) . If a project triggers a National Environmental Policy
Act (NEPA) environmental review, the project is reviewed under the FAA’s NEPA environmental review
process. Chapter 4, Airport Planning , discusses current and potential future projects and their respective
regulatory review status under MEPA, NEPA, or both. Chapter 10, Project Mitigation , reports on the on-
going implementation of required mitigation commitments made in project-specific MEPA filings.
1.2.3 Document Layout and Format
In response to the comments within the Secretary of the Executive Office of Energy and Environmental
Affairs’ Certificate, (see Appendix A) and Comment Letters (see Appendix B, Comment Letters and
Responses to Comments ), Massport has reassessed the format and content of each chapter and the ESPR
document as a whole, and as a result, has made significant changes to improve overall accessibility and
readability. Content from each chapter was reorganized to keep 2022 findings and future forecast
conditions, where applicable, as the central focus point within the main body text. Where appropriate,
more technical information was relocated to the technical appendices.
To enhance content accessibility and reduce confusion around technical jargon, tables providing key
terminology with definitions were added to assist readers. Key terminology is defined in bold colored font
when first used in the main text. A new format was used to reduce large, information-dense blocks of text,
and more visual elements were added with straightforward depictions of information.
Each chapter has color-coded block icons, or “tabs,” in the upper corner of each page with a unique color
assigned to each chapter and corresponding chapter number icon centered in the color block. For
electronic viewers, the table of contents preceding this chapter has been hyperlinked to allow the reader
to easily jump to sections quickly. Chapter and section references within the main body of the text have
also been bookmarked and hyperlinked.
Individual projects must also
undergo MEPA review if they
meet environmental regulatory
review thresholds.

1.3.2 Activity Levels and Forecast
Chapter 3, Activity Levels and Forecasting studies the recent trends in passengers, operations, and cargo at
Logan Airport.
After COVID-19, 2022 saw an increase in activity, but still below 2019 levels. Chapter 3 describes the
methodology for developing forecasts and reports on forecasted future airport activity, looking 10 to 15
years ahead over the Future Planning Horizon. These forecasts help to inform airport planning for
potential future growth and are used to estimate future environmental conditions. The future forecast is
developed considering factors such as global and regional economic trends, technological changes, and
future airline actions. Updates within Chapter 6, Ground Access , Chapter 7, Noise , and Chapter 8, Air
Quality and Greenhouse Gas Emissions each use outcomes derived from the Future Planning Horizon
forecast to assess anticipated future conditions at Logan Airport.
Activity Levels and Forecasting 2022 Key Findings
36.1 million passengers in 2022 378,613 Operations in 2022
From 1998 to 2022, there was a 36 percent
increase in annual

1.3.3 Airport Planning
Chapter 4, Airport Planning describes recently completed and on-going projects as well as future planning
concepts. By regularly updating this information, stakeholders can track various projects currently
underway and get a preview of potential projects likely to begin over the coming years. Chapter 4 also
discusses possible activities or projects that might require a review under NEPA or MEPA regulations.
In this chapter, projects are grouped into the following categories: terminal areas; airside areas; service
areas; ground access and parking; Massport’s efforts to promote high-occupancy vehicle (HOV) ridership;
and open spaces. Chapter 4 prioritizes providing status information for those projects delayed or deferred
as a result of the pandemic, especially those projects intended to reduce operational or environmental
impacts. Future projects are categorized as either short-term when the project is anticipated to be
completed by 2028, or long-term if the project is anticipated to be complete or fully implemented by
2035.
Airport Planning Key Findings
Phase 1 of the Terminal E Modernization project
was under construction in 2022 and four new
gates opened in 2023. The project has many
sustainability features and is seeking Leadership
in Energy and
Environmental
Design (LEED®)
certification.
To improve safety and efficiency, Massport moved
the RideApp access area to the Terminal B Garage
in 2022. This provided 60 more parking spots in
the Central Garage, 4 of which were for electric
vehicles . Massport continued to implement a
parking management strategy to encourage HOV
and shared ride options.
In 2022, Massport completed post-security
connections between Terminals B and C, initiated
feasibility studies for connections between
Terminal A and Terminals B and E, and expanded
passenger amenities following the completion of
the Terminal B Modernization Project. Terminal
roadways between Terminals B and C were
reconfigured to improve access and reduce
congestion.
Planning for the Logan
Airport Parking Project in
front of Terminal E,
resumed in 2022, after
deferment during the
pandemic. The updated
project program will add
approximately 4,300 spaces within the central
terminal area to encourage long-term parking and
will also improve on-Airport roadway connectivity.

1.3.4 Regional Transportation
Chapter 5, Regional Transportation reports on Logan Airport’s role in the wider New England
transportation system, which includes other airports, highways, ports, and rail connections. Logan Airport,
which is the largest of three airports run by Massport, is the main domestic and international entry point
for the Boston Metropolitan Area and the New England region.
Chapter 5 presents 2022 aircraft and passenger activity levels as well as on-going and up-coming projects
at airports in New England. In the last ten years, more people have been using rail connections between
Boston, New York City, and Washington, D.C. as an alternative option for travel between these cities rather
than choosing air travel via Logan Airport. Chapter 5 details transportation planning for the New England
region for various transportation modes.
Regional Transportation 2022 Key Findings
New England regional airports, excluding Logan
Airport, served approximately 15 million
passengers in 2022.
New England’s 10 regional
airports served 30 percent
of New England’s
passengers in 2022.
The remaining 70 percent
of New England
passengers were accommodated at Logan Airport.
New England regional airports, excluding Logan

1.3.5 Ground Access
Chapter 6, Ground Access evaluates trends in surface transportation modes used to access the Airport,
including personal vehicles, shared ride services or RideApp services, shuttles, and HOV modes. Post-
pandemic research indicates Logan Airport continues to be one of the top U.S. airports in terms of airport
passengers and employees that routinely utilize HOV and public transit modes of transportation. Each
type of ground transportation service available in 2022 showed increased ridership, demonstrating the
use of the various access modes to Logan Airport are returning to pre-pandemic levels.
Massport continues to monitor conditions both at the Airport and among surrounding areas, and adapts
its ground access programs to meet the needs of both air passengers and Logan Airport employees.
Ground Access 2022 Key Findings
Average weekday on-Airport vehicle miles
traveled (VMT) was 164,625 average daily miles
traveled.
High occupancy vehicle
(HOV) mode share reached
38 percent; exceeding
Massport’s goal of 35.5
percent HOV mode share by
2022.
Each type of ground transportation service
available in 2022 showed increased ridership
compared to 2021, indicating access modes to
Logan Airport are returning to pre-pandemic usage
levels and trends.
As requested by the community, Massport
conducted a dwell time study, which measured
actual durations of vehicle time spent idling at
curbs and confirmed these times typically aligned
with those modeled. Personal vehicle dwell times
were longer outside of peak travel times when
fewer vehicles were at the curb.

Ground Access Future Planning Horizon Key Findings
Massport has and continues to make investments
into Logan Express to accommodate future
passengers’ needs. Investments include increasing
parking availability at key Logan Express sites,
enhancing service frequency, adding new a new
urban location, and considering pricing incentives.
In addition to Logan Express, Massport continues
to incentivize HOV use for travel to and from the
Airport. Measures like prioritizing certain Logan
Airport roadways to optimize bus fleet operations,
investments in and the expansion of Silver Line 1,
continuing on-going and future improvements to
Blue Line access, and continuing partnerships with
private bus companies will encourage HOV use.
In the Future Planning
Horizon, VMT is anticipated
to increase by 1 percent
compared to 2019 VMT
values.
Massport continues to identify infrastructure and
operational modifications that would improve
vehicular traffic flow at the Airport. For example,
the Terminal B/C Roadway Project and RideApp
access planning efforts are already complete and
will have a lasting benefit to future operations at
the Airport.
1.3.6 Noise
Chapter 7, Noise discusses the noise levels around the Airport in 2022 and Massport’s on-going efforts to
decrease aviation related noise at Logan Airport. Airport noise is measured using comprehensive flight
information and the FAA's required noise model, which calculates noise exposure levels in decibels (dB) .
Chapter 7, focuses on noise exposure levels in relation to the FAA level of significance (65 dB) for 2022
and the Future Planning Horizon. Chapter 7 also describes Massport's efforts over the past four decades
to manage the impacts of noise on surrounding communities.
When noise exposure levels in 2022 were compared to data from previous years, the analysis revealed the
geographic extent of the Airport’s noise contours had decreased in recent years due to the retirement of
older, noisier aircraft. In addition, future operations based on activity forecasts were used to model
anticipated noise levels for the next 10 to 15 years, and these models predicted quieter environments due
to expected advances in avionics and aircraft technology.

To date, Massport has invested over $170 million
and provided sound insulation for 36 schools and
11,515 residential units. In 2022, Massport sought
additional noise mitigation funding for eligible
properties through Massport’s Residential Sound
Insulation Program (RSIP). The Noise Exposure
Map (NEM) was updated to confirm eligibility, and
Massport established a pilot program with the FAA
to sound insulate eligible homes and re-evaluate
sound insulation in homes treated before 1993.
Massport upgraded its Noise and Operations
Monitoring System (NOMS), including 29 of the 30
monitors around Boston.
There were 1,301 noise
complaint callers in 2022,
which is 51 percent fewer
callers than in 2019.

1.3.7 Air Quality and Greenhouse Gas Emissions
Chapter 8, Air Quality and Greenhouse Gas Emissions provides details about Logan Airport's air emissions
in 2022 in comparison to historical data. Airport emissions generally come from various sources including
aircraft, ground service equipment (GSE), vehicles, buildings, and stationary sources. Tracking these
emissions each year helps identify trends and enables future planning to reduce these emissions.
Chapter 8 focuses on emissions of criteria pollutants and GHGs for 2022 and over the Future Planning
Horizon.
Although aircraft activity levels have increased somewhat, technological advancements have led to
reduced overall emissions. However, Massport's strong commitment to reducing emissions and energy-
efficient strategies are expected to result in future emission levels remaining well below historical levels.
Air Quality and GHG Emissions 2022 Key Findings
In 2022, the Boston Metropolitan Area, which
includes Logan Airport, continued to remain below
national ambient air quality standards (NAAQS) in
2022. Criteria pollutants include:
• Volatile organic compounds (VOCs),
• Nitrogen oxides (NO X )
• Carbon monoxide (CO)
• Particulate matter ( PM 10 /PM 2.5 )
CO and VOC emissions in
2022 remained well below
recorded historic highs for
these emissions.
In 2022, Logan Airport Scope 1 and 2 greenhouse
gas (GHG) emissions remained well below 2019
GHG levels.
Massport-controlled, Scope 1 emissions
represented 5.4 percent of Airport-wide GHG
emissions; in-direct emissions from Scope 2
purchased electricity represented 7.3 percent; and
Scope 3 emissions, which are public or tenant
owned and controlled, represented 87.3 percent of
total Logan Airport GHG emissions.
Logan Airport GHG emissions represented less
than 1 percent of the state’s GHG totals.
In 2022, PM 10 /PM 2.5
emissions from stationary
sources and other non-
mobile sources were also
greater than 2019 and
2021 levels. These sources
include snowmelters,
boilers, emergency
generators, space heaters, and emissions from fire
training activities. Results were also affected by
changes in modeling assumptions for the
assessment of 2022 data.

Introduction and Executive Summary 1-16
1 Boston Logan International Airport 2022 ESPR
Air Quality and GHG Emissions Future Planning Horizon Key Findings
In the Future Planning Horizon, criteria pollutants
will remain below national ambient air quality
standards (NAAQS). Criteria pollutants are
predicted to increase and total emissions of
carbon monoxide (CO) are predicted to decrease
compared to 2022 levels. Reductions in CO
emissions will be associated with converting
ground service equipment (GSE) to commercially
available electric alternatives, overall decreases in
motor vehicle emissions, changes in aircraft fleet-
mix, and emission reductions from implementing
the Roadmap to Net Zero by 2031 (Net Zero by
2031) program.
Over the Future Planning
Horizon, Massport’s
Scope 1 GHG emissions are
anticipated to decrease by
nearly 90 percent
compared to 2022
emissions. However, Scope
2 and 3 emissions are
anticipated to increase from 2022 levels.
For instances when GHG emissions cannot be
reduced to zero, Massport will invest in carbon
offsets to reach the target.
Massport is focused on
reducing GHG emissions
across all facilities and
becoming net zero for Scope
1 activities under its direct
control by 2031, coinciding
with its 75th anniversary.
Massport’s intends to purchase offsets that will
benefit local projects within the State whenever
practicable.
Massport expects to be net zero for GHG
emissions without offsets by 2040.

Introduction and Executive Summary 1-17
Boston Logan International Airport 2022 ESPR 1
1.3.8 Water Quality
Chapter 9, Water Quality discusses the Airport’s compliance with state and federal environmental
regulations. Through regular monitoring and documentation of environmental conditions, Massport
regularly assesses the Airport’s environmental compliance program performance, including conditions like
water and stormwater quality; fuel use and storage; and spill control and countermeasures. Massport is
also continually developing, implementing, and evaluating new ways to maintain compliance standards
while striving to improve policies and programs beyond regulatory mandates. This includes implementing
Logan Airport’s Sustainability Management Plan (SMP); managing stormwater; minimizing water use and
surface water runoff; maintaining fuel storage and spill reporting compliance; performing environmental
inspections; and improving plans and procedures to prevent pollution from accessing the surrounding
environment.
Water Quality 2022 Key Findings
In 2022, Massport performed environmental
compliance inspections, conducted its annual
Stormwater Pollution Prevention Plan (SWPP P )
update meeting, and submitted the 2022 Annual
Certificates of Compliance to the U.S.
Environmental Protection Agency (U.S.EPA) and
Massachusetts Department of Environmental
Protection (MassDEP).
In 2022, over 97 percent of
stormwater samples
collected were in
compliance with standards
for pH, oil and grease, and
total suspended solids
(TSS).
In 2022, 3 fuel spill incidents were over 10 gallons,
but none of these resulted
in pollutant exposure to
stormwater infrastructure
or the discharge of
pollutants to the aquatic
environment.
Massport continues to assess, remediate, and
bring its Massachusetts Contingency Plan (MCP)
sites to regulatory closure.

1.3.9 Project Mitigation
Within the traditional MEPA process, “project mitigation” refers to specific project measures to “avoid,
minimize, and mitigate environmental impacts.” For the ESPRs and EDRs, the chapters associated with
mitigation efforts include: project-specific mitigation required under Massachusetts General
Law (MGL) c. 30, §§ 61 ( Section 61 ) for projects required to prepare a state EIR; community commitments;
and other environmental measures.
The Section 61 mitigation measures discussed in Chapter 10, Project Mitigation are specific to individual
projects and generally include the steps taken to avoid and minimize potential environmental impacts
through project design, construction, or during on-going operations. The status of Logan Airport projects
with active Section 61 commitments are presented in Chapter 10, while additional community
commitments and environmental measures are discussed in Chapter 2, Sustainability, Outreach, and
Environmental Justice .
Project Mitigation 2022 Key Findings
Within the MEPA process, Project Mitigation”
refers to specific project measures to “avoid,
minimize and mitigate environmental impacts.”
Project mitigation commitments outlined within a
required Environmental Impact Report (EIR) for a
project are required by law under Massachusetts
General Law (MGL) Chapter 30, Section 61.
Massport also implements a wide range of other
environmental programs that are not project-
specific but rather aimed at addressing broader
environmental impacts. These measures are
described in Chapter 2, Sustainability, Outreach,
and Environmental Justice .
The COVID-19 pandemic significantly reduced
airport activity levels and revenue; prompting
Massport, airlines, and other tenants to make
operational adjustments. However, projects and
programs deferred due to the reduced passenger
levels have begun to resume.
Massport continues to comply with its project
mitigation commitments as outlined in Project’s
Secretary’s Certificates, included in Appendix A,
MEPA Certificates and Responses to Comments .

This is a new chapter within the 2022 ESPR that reorganizes and enhances information provided in
previous Environmental Status and Planning Reports (ESPRs) and Environmental Data Reports (EDRs) on
Massport’s sustainability and resiliency efforts, environmental measures, and outreach and engagement
activities associated with Logan Airport activities. In alignment with recent changes to Massachusetts
Environmental Policy Act Office (MEPA) regulations, this chapter also discusses Massport’s Environmental
Justice (EJ) practices. This chapter provides an overview of measures Massport takes to avoid, minimize,
and mitigate the environmental impacts of Airport operations and efforts to be a good neighbor to
surrounding communities.
Chapter 10, Project Mitigation , details the project-specific mitigation for projects that met the MEPA
requirements for preparation of an Environmental Impact Report (EIR). Beyond the measures required for
individual projects, Massport also implements a wide range of ongoing initiatives to enhance operational
efficiency and reduce overall Airport environmental impacts. Details on Massport’s community open space
and Airport edge buffers program are also presented in this chapter.
The following sections describe Massport’s community engagement practices, EJ-focused measures, and
Massport-wide sustainability and resiliency initiatives. Key environmental initiatives presented in this
chapter include Airport-wide sustainability and resiliency programs, greenhouse gas (GHG) emissions
reduction programs, and Massport’s ambitious climate change initiative, the Roadmap to Net Zero
by 2031 ( Net Zero by 2031 ) .

2022 Sustainability, Outreach, Environmental Justice and Key Findings
The following details key findings regarding sustainability, outreach, and EJ efforts at the Airport in 2022:
 The Act Creating a Next-Generation Roadmap for Massachusetts Climate Policy (the Climate Roadmap
Act) was signed into law in March 2021 and set targets for GHG emissions reduction in the state,
including a goal of net zero GHG emissions by 2050. In support of this goal, Massport published its
Net Zero by 2031 plan to achieve net zero GHG emissions from Massport facilities by 2031.
 Massport’s Community Relations & Government Affairs Department manages outreach efforts with
community members and government officials through extensive and evolving public involvement
practices that include engagement with neighbors and EJ communities.
 For this and future EDRs and ESPRs, Massport has expanded its EJ outreach to provide translation
services in languages spoken by at least 5 percent of a given population located within a 5-mile radius
of Logan Airport or within Massport Community Advisory Committee (Massport CAC) communities.
 The Massport CAC is made up of 35 representatives from impacted communities and serves as a
forum for information sharing on projects, Massport initiatives, and other topics of interest.
 Massport conducted an EJ and public health existing conditions review. The Logan Airport
designated geographic area (DGA) contains 64 EJ block groups, and both EJ and non-EJ
populations within the DGA meet the Vulnerable Health EJ Criteria; meaning these populations likely
experience health consequences consistent with the Vulnerable Health EJ Criteria.
 Massport continues to develop initiatives to limit cumulative environmental impacts from Airport
operations.
 Massport funds community foundations in East Boston, South Boston, and Winthrop; each of which
has a Board of Trustees that meets regularly to award grant funds to community programs and
organizations that help improve the quality of life for residents.
 Since 2014, Massport has funded the East Boston Neighborhood Health Center’s efforts to expand its
Pediatric Asthma and Chronic Obstructive Pulmonary Disease (COPD) Prevention and Treatment
Program.
 Each year, Massport awards scholarship grants to local high school seniors. Since 2007, Massport has
awarded nearly $300,000 in scholarship grants for Diversity Science, Technology, Engineering, and
Math (STEM) and Memorial Scholarships. Massport awards over $250,000 in grants to local non-profit
organizations through the Charitable Contribution Program each year. Massport has set a goal to
award at least 50 percent of the program's budget to programs predominately serving people of
color.

2.1 Sustainability, Climate Adaption, and Resiliency
As the Boston area faces increasing temperatures, more frequent extreme weather events, and rising sea
levels due to climate change, Massport recognizes the need to address its contributions to climate
change; to thoroughly prepare for related impacts; and to protect its critical infrastructure, operational
assets, and workforce. Through planning and regional collaboration, Massport will continue its leadership
role in climate adaptation and resiliency planning in the region and among port authorities and the
airport industry. For almost a decade, Massport has committed to improving its overall climate adaption
and resiliency performance through implementing strategies including floodproofing buildings,
operational planning for storm preparedness, innovative partnerships, regional collaboration, and
reducing GHG emissions associated with Massport
operations and activities.
The following sections summarize the long-term and
multifaceted sustainability initiatives undertaken by
Massport. A history of Massport’s sustainability planning is
illustrated in Figure 2-1 , and more information about
Massport’s resiliency programs is available at:

2.1.1 Massport Roadmap to Net Zero Greenhouse Gas Emissions
On March 26, 2021, the Climate Roadmap Act was signed into law, setting GHG interim targets for the
state. 1 Targets include a 50 percent reduction in absolute GHG emissions by 2030, a 75 percent reduction
by 2040, and an absolute GHG emissions reduction to 85 percent or less than 1990 GHG emission levels
by 2050. The law also requires statewide net zero GHG emissions by 2050. These targets align with the
federal government's net zero timeline and the 2015 Paris Agreement enacted by the United
Nations (U.N.). 2,3 According to the U.N., achieving global net zero GHG emissions by 2050 is a crucial
international goal to avert the worst impacts of climate change and preserve a habitable planet. 4

In March 2022, Massport published its Roadmap to Net Zero by 2031, 5 an
ambitious, Authority-wide program to achieve net zero GHG emissions by
2031 for the activities under Massport’s control. The 2031 timeframe also
coincides with the 75 th anniversary of Massport’s founding. For areas where
GHG emissions cannot be reduced to zero, Massport will invest in carbon
offsets to reach the target. Massport expects to be net zero without offsets by
2040. Carbon offsets are investments in GHG-reducing projects, such as solar
farms, which lessen the overall impact of, or offset, an organization’s own GHG
emissions. Massport’s preference is to purchase offsets that benefit local
projects within the State. Achieving these net zero targets would put Massport
nearly two decades ahead of the 2050 deadline called for in the Paris
Agreement and the Climate Roadmap Act. As a key economic entity within the
state, Massport will be a leader in achieving net zero within the State and the
transportation industry.
Existing GHG Emissions at Massport
To assess the pathways for achieving net zero, Massport established a GHG emissions baseline across its
organizational footprint. As is standard, Massport inventoried and then categorized its emissions sources
into Scopes 1, 2, and 3.
Scope 1 emissions sources are under Massport’s direct
control, such as emissions associated with buildings, facilities,
Logan Airport’s Central Heating Plant, and Massport’s vehicle
fleet and equipment. Massport owns or has direct control of
sources, and retrofits or replacements would eliminate these
GHG emissions.
Scope 2 emissions sources are not directly within Massport’s
control, but Massport has some ability to limit or remove these
sources. An example would be purchased electricity from an electrical utility provider. Massport may have
the option to purchase renewably sourced electricity from one utility over another, but cannot affect what
providers are available or influence its ability to meet Massport’s energy demands.
Scope 3 emissions sources are not under Massport’s control or ownership, like those of Airport users
and tenants. However, Massport encourages and supports these groups to voluntarily implement GHG
emission reduction initiatives. Examples of Logan Airport’s Scope 3 sources include energy consumed by
tenant-owned or operated facilities or equipment, like fleet vehicles, commercial aircraft, or ground
service equipment (GSE) for example, or from sources like employee and passenger ground
transportation. While Massport cannot control, for example, whether a passenger will use their personal
5 2031 marks the 75th anniversary of the establishment of Massport.
Scope Emissions at Logan Airport:
 Scope 1 and 2 = 12.5%
 Scope 3 = 87.5%
Scope 1 and 2 emissions make up 10.8%
of Massport’s total emissions

vehicle, Massport makes high-occupancy vehicle (HOV) use and public transportation options more
accessible or affordable, thereby incentivizing GHG emissions-reducing behavior.
Between 2017 and 2019, Massport conducted an inventory of GHG emissions across its facilities. GHGs as
a group are comprised of gases including carbon dioxide (CO2), methane (CH4), carbon monoxide (CO),
and nitrous oxide (N2O). For ease of reporting, Massport follows a common industry practice of
converting measured GHG concentrations into metric tons of CO2 equivalent (MTCO2e). 6 In 2019, Logan
Airport's total emissions were 808,125 MTCO2e, with 51,359 MTCO2e from Scope 1 sources,
43,226 MTCO2e from Scope 2, and 713,540 MTCO2e from Scope 3. Logan Airport comprises
approximately 86 percent of Massport’s total Scope 1 and Scope 2 GHG emissions. Other relevant
contributors to this total GHG emissions quantity include the Paul W. Conley Container Terminal and
Flynn Cruiseport Boston, comprising 12 percent combined, and Laurence G. Hanscom Airfield and
Worcester Regional Airport, comprising 2 percent combined.
Net Zero Roadmap
To meet Massport’s net zero goals, five pathways were identified as illustrated in Figure 2-2 . These
pathways address the largest sources of Massport’s controlled GHG emissions as well as the emissions it
influences. These pathways also consider ways Massport can achieve additional sustainability benefits,
such as advancing innovation within the industry and promoting collaboration and engagement through
partnerships and Authority-wide engagement.

implementation of Massport’s Net Zero by 2031 program. The PMO guides the Authority towards
achieving its net zero goals and objectives and assists Massport by:
 Assisting with implementing the pathways and initiatives identified in the Net Zero by 2031 program; 7
 Providing strategic thinking and planning for ongoing capital improvement projects and purchases;
 Identifying technological improvements and other forms of innovation pertinent to net zero;
 Tracking progress towards achieving net zero target goals and interim milestones;
 Working to verify that the net zero goal is understood and is positively affected by Massport’s
employees, business partners, and customers.

2.1.2 Sustainability Planning and Implementation
The Net Zero by 2031 program builds on over a decade of sustainability
and resiliency planning undertaken by Massport for its facilities and
activities. Completed in 2015, the Federal Aviation Administration (FAA)-
funded Logan Airport’s Sustainability Management Plan (SMP) addresses
sustainability holistically; considering economic vitality, operational
efficiency, natural resource conservation, and social responsibility. The
Logan Airport’s SMP established a framework of goals, objectives, and an
implementation plan with key performance indicators (KPIs); Table 2-2 lists
the Logan Airport’s SMP’s goals and objectives by sustainability category.
The Logan Airport’s SMP was then expanded into an Authority-wide
Sustainable Massport program that addressed airport, maritime, and real
estate assets. The Sustainability and Resiliency Report 8
(Sustainable Massport 2.0) builds and expands on the work started with
Logan Airport’s 2015 SMP. Having tracked progress on its sustainability
goals for over a decade, Massport has a solid foundation for the Roadmap
to Net Zero by 2031 described in Section 2.1.1.
The 2020 and 2021 Sustainability and Resiliency Report , included new initiatives that Massport explored to
be a better community partner through reducing noise and air pollution, improving ground access to
Logan Airport, and extending diversity, equity, and inclusion (DE&I) initiatives beyond its operational
borders.
The progress made towards achieving the Logan Airport’s SMP program’s goals and objectives is
published in sustainability reports, which also highlight Massport’s efforts to improve and enhance
sustainability and climate resiliency across the entire organization. The most current Massport
Sustainability, Net Zero, and Resiliency Reports can be found at: https://www.massport.com/sustainability.

Resiliency Planning
Climate change is a real and urgent issue, causing a wide range of increasingly significant impacts such as
rising sea levels, extreme storms, heavy precipitation, coastal flooding, and extreme heat. Massport
recognizes the importance of taking action to mitigate and prepare for these impacts to protect critical
infrastructure, operations, and surrounding communities. Massport embraces an integrated,
comprehensive approach to climate change through resiliency planning and adaptation.
In 2013, Massport launched a comprehensive resiliency initiative to maximize business continuity amidst
various human and natural threats. Massport’s efforts are guided by the following goals:
 Improve resiliency overall for infrastructure and operations;
 Restore operations during and after disruptive events in a safe and economically viable timeframe;
 Create robust feedback loops that allow for adaptability and new solutions as conditions change;
 Adapt operations and policy, and implement design-build decisions, through the application of sound
scientific research and principles that consider threats, vulnerabilities, and cost-benefit calculations;
 Become the ideal model of a knowledge-sharing, forward-thinking, and resilient port authority;
 Work with key influencers and decision-makers to strengthen understanding of the human, national,
and economic security implications of extreme weather, changing climate, and anthropogenic threats
to Massport's facilities and the region;
 Review capital programs, tenant alterations, real estate projects, and asset management projects for
compliance with Massport’s Floodproofing Design Guide (see
https://www.massport.com/environment/sustainability/resiliency); and
 Conduct annual pre-hurricane season tabletop exercises and flood barrier training exercises.
In addition to protecting Massport-owned assets, the Authority has been collaborating with regional
resiliency efforts, including the Massachusetts Executive Office of Energy and Environmental Affairs (EEA)
ResilientMass program, U.S. Army Corps of Engineers (U.S.ACE), and City of Boston initiatives to protect
surrounding communities. Massport’s open space and airport edge buffer parks are an example of this
district-scale resiliency approach. As described in Section 2.2.3.9, Massport has worked with communities
to develop a system of parks and open spaces encompassing over 30 acres. These green spaces capture
GHG emissions, provide relief from extreme heat, and create recreational opportunities, and waterfront
parks, like Piers Park I and II and the Navy Fuel Pier Buffer, establish a buffer area for neighborhoods in
the event of extreme flooding.
2.1.3 Sustainable Design and Construction Guidelines
Massport is committed to being a leader in sustainable design and construction across all of its business
lines, including Logan Airport. New construction and reconstruction or rehabilitation projects for both
physical buildings and infrastructure of any square footage or monetary value at the Airport are
considered within Massport’s comprehensive approach to sustainability and resiliency within the built
environment.

Sustainability, Outreach, and Environmental Justice 2-11
Boston Logan International Airport 2022 ESPR 2
Design Guidelines for Sustainability, Net Zero, and Resiliency
The 2018 edition of Massport’s Sustainability and Resiliency Design Standards and Guidelines
(SRDSGs) codifies the sustainable practices Massport is currently working to achieve. These practices,
documented in the Logan Airport’s SMP and subsequent sustainability and resiliency reports, are
requirements for both vertical and horizontal projects on Massport property. As applicable and feasible,
the SRDSGs reference and incorporate state and local policies and plans such as the Global Warming
Solutions Act of 2008 and the Boston Zoning Code Article 37.
The standards are currently being updated to reflect the latest net-zero criteria and address topics like
embodied carbon emissions and occupant health and wellness. More recent state and local policies, such
as the 2021 Climate Roadmap Act , the Massachusetts Clean Energy and Climate Plan for 2025 and 2030 ,
House Bill 5060: An Act Driving Clean Energy and Offshore Wind , and House Bill 5151: An Act Relative to
Massachusetts’s Transportation Resources and Climate (MassTRAC), will also be referenced in the update to
the SRDSGs, which is planned for publication in 2024.
Sustainability Rating Systems
Massport’s SRDSGs include requirements from industry-leading green building rating systems, such as the
U.S. Green Building Council’s (U.S.GBC) Leadership in Energy and Environmental Design™ (LEED®) rating
system. 9 If LEED® eligible, Massport-owned projects must achieve LEED® Gold Certification or higher.
Table 2-3 lists LEED®-certified Massport facilities. In addition to U.S.GBC’s LEED® Certification
requirement, Massport’s next iteration of its SRDSGs is expected to incorporate the Institute for
Sustainable Infrastructure’s (ISI’s) Envision™ rating system. 10
9 The Leadership in Energy and Environmental Design™ (LEED®) rating system is a globally recognized green building certification
system developed by the U.S. Green Building Council (U.S.GBC). It provides a framework for healthy, highly efficient, and cost-
saving green buildings, and indicates sustainability achievement and leadership.
10 The Institute for Sustainable Infrastructure’s (ISI’s) Envision™ rating system is a comprehensive framework and certification system
that assesses the sustainability of infrastructure projects across five categories: quality of life, leadership, resource allocation, natural
world, and climate and resilience.

2.2 Massport Community Engagement and Environmental
Initiatives
Massport has and will continue to champion community benefits and robust community engagement.
Working in concert with government, community, and civic leaders throughout Massachusetts and New
England, Massport is actively engaged in advancing environmental initiatives and expanding community
programs for residents living near Massport’s facilities.
2.2.1 Massport Community Giving
Each year, the Massport Charitable Contribution Program provides grants to community organizations
to help fund programs in areas such as youth education, arts and culture, social service, the environment,
and athletics. Massport has set a goal to award at least 50 percent of the program budget to
organizations serving predominately people of color. In fiscal year 2022 (FY 2022), Massport surpassed
this goal by awarding 69 percent of the total FY 2022 budget to organizations or programs serving
predominately people of color. A full list of the community organizations funded by Massport in FY 2022
can be found in Appendix E, Environmental Justice Supporting Materials , Section E.1.
In 2022, Massport distributed $600,000 to fund 275 youth summer employment positions through the
Community Summer Jobs Program . The annual program helps civic and social service agencies by
providing funds to hire youth workers in Massport’s neighboring communities including Bedford,
Charlestown, Chelsea, Concord, East Boston, Lexington, Lincoln, Revere, South Boston, Winthrop, and
Worcester. Without the assistance of Massport’s Community Summer Jobs Program, many local
organizations would not be able to offer affordable summer programs to residents. Since 1991, thousands
of local students have gained valuable work experience in various jobs, such as camp counselors, office

Sustainability, Outreach, and Environmental Justice 2-16
2 Boston Logan International Airport 2022 ESPR
assistants, maintenance workers, and lifeguards; positions funded by Community Summer Jobs Program
grants.
Massport collaborated with local and state governments, municipalities, and other charitable
organizations to establish and fund the East Boston Foundation, South Boston Foundation , and
Winthrop Foundation . Beginning with the East Boston Foundation in 1997, Massport has provided over
$16 million in funds for vital programs in these highly impacted communities. In 2022, the community
foundations awarded over $600,000 to local organizations, helping to improve the quality of life for area
residents.
Massport provides annual funding to the East Boston Neighborhood Health Center to help expand the
efforts of its Pediatric Asthma and Chronic Obstructive Pulmonary Disease (COPD) Prevention and
Treatment Program in East Boston and Winthrop. The program provides services including screenings for
children, distribution of asthma kits, and home visits.
Massport awarded Diversity STEM and Memorial Scholarships to six local students in 2022. Each year,
high school students are selected to receive two Diversity STEM Scholarships and the Thomas J. Butler,
Deborah Hadden Gray, Donna Rauseo, and Lowell L. Richards III Memorial Scholarships based on their
academic achievements, post-secondary educational plans, and demonstrated commitment to community
service. Since 2007, Massport has awarded Diversity STEM Scholarships to 46 students of color who plan
to pursue degrees in a STEM field. Since 2011, Massport has awarded Memorial Scholarships to
38 students. Massport also provides annual scholarship grants to local high schools for students in
Charlestown, Chelsea, East Boston, South Boston, Revere, and Winthrop.
As part of Massport’s history of community engagement, Massport employees volunteer in community
activities throughout the year such as a children’s winter coat drive, Veterans Day initiatives, a
Thanksgiving food drive, a children’s backpack drive, a women’s shelter donation drive, and community
beautification projects.
2.2.2 Diversity, Equity, and Inclusion (DE&I)
As an engine for economic growth, Massport continually strives to extend economic opportunities and
create equity for diverse people and businesses, internally and in surrounding communities. Leveraging
real estate to bring more Bostonians to the table, Massport pioneered a DE&I model, known as the
“Massport Model,” for its real estate development programs and projects to expand economic
opportunities through a competitive, market-driven process. The Massport Model focuses on including
people of color and women in significant ownership and leadership roles in every aspect of a project, from
development to property management. The model does not prescribe how to incorporate DE&I, but
instead gives the private sector the flexibility to propose new and creative approaches.
The Massport Model was first applied in 2016 for the project to develop the Omni Boston Hotel at the
Seaport. In that competitive bid, Massport said DE&I was as important as traditional evaluation criteria;

namely financials, design, and ability to execute. Smaller, women- and minority- owned firms, businesses
historically excluded from large projects in the city, partnered with some of the region’s largest
development, architecture, and construction firms to bid, which resulted in a broadly diverse team as well
as $7 million in equity from minority investors.
The Massport Model continues to evolve with the Seaport Circle project,
which will house the South Boston Waterfront Job Training Pavilion and
benefit a wide array of Bostonians by providing workforce training for
high school graduates and underserved residents. The most recent
application of the Massport Model was an RFP issued in 2021 for a
mixed-income, affordable housing project on D Street in South Boston.
Proposals will be evaluated equally for DE&I commitments, housing
affordability, design, and ability to execute. The Massport Model has also
begun to be emulated by other agencies and municipalities.
2.2.3 Environmental Initiatives
Massport is committed to minimizing the effects of its operations on the community and environment by
implementing a comprehensive set of Airport-wide initiatives that benefit the neighbors, Airport users,
Airport employees, and the traveling public. These include, but are not limited to, the environmental
initiatives listed in the following sections, which Massport has undertaken to lessen the Airport’s
environmental impacts. These initiatives are different from formal project environmental mitigation
commitments as they are not tied to projects, and more generally reduce overall operational and
environmental impacts from Airport sources. Conversely, MEPA Section 61 commitments are binding
mitigation commitments made in past MEPA project filings developed by Massport to address
project-specific environmental impacts. Updates on implementing Section 61 commitments for projects
requiring mitigation are detailed in Chapter 10.
2.2.3.1 High-Occupancy Vehicle (HOV) Strategy
Massport employs numerous strategies to provide ground transportation options for Logan Airport
passengers and employees to reduce emissions associated with accessing the Airport. Massport’s goal is
to maximize the use and capacity of HOV, transit, and RideApp options that are convenient and reliable
and reduce environmental and community impacts. Massport continues to promote, operate, and support
HOV and RideApp services to improve operations along Terminal-area roadways and at curbside areas,
alleviate parking constraints, improve customer service, and minimize emissions.
Massport regularly evaluates and updates its strategies to improve and expand Logan Airport ground
access services with a strong focus on HOV service modes. Central to this strategy is continued investment
in Logan Express facilities and service. Logan Express is the seventh largest transit system in
The Massport Model sets a policy
to consider DE&I evaluation
criteria and incorporating DE&I
into project plans and execution to
be as important as traditional
architecture, design, and
construction considerations.

Massachusetts and annually carries passengers and Airport employees between Logan Airport and five
metropolitan locations.
Logan Express schedules were adjusted in March 2020 in response to the COVID-19 pandemic and the
subsequent decline in ridership. As of October 2022, all Logan Express services have been restored
following pandemic-related service cuts. The historically underperforming Peabody Logan Express
operation has been relocated to a more convenient location at the North Shore Mall, the Back Bay Logan
Express service has been restored, and plans are currently moving forward to expand the Framingham
Logan Express parking garage. More information can be found in Chapter 6, Ground Access ,
Section 6.3.1.2, and Chapter 4, Airport Planning , Section 4.1.
In close partnership with the Massachusetts Bay Transportation Authority (MBTA), Massport purchased
eight Silver Line rapid transit buses in 2004 for service between the Logan Airport Terminals, South
Station, and South Boston. Since the existing Silver Line fleet is reaching the end of its useful life,
Massport has recently purchased ten new Silver Line electric or hybrid buses as part of an MBTA
procurement program. This will allow expansion of Silver Line service between Logan Airport and
downtown. Since 2012, Massport has subsidized free Silver Line rides from the Airport to South Station.
More information can be found in Chapter 6 .
2.2.3.2 RideApp Management
RideApp services like Lyft™ and Uber™ remain a popular option for travelers getting to and from Logan
Airport. Massport has developed strategies and will continue improving approaches to facilitate the
efficient operation of diverse modes of ground transportation. To alleviate congestion and reduce GHG
emissions, Massport has implemented a robust plan to manage RideApp operations and reduce RideApp
deadhead trips. 11 For more detailed information on Massport’s RideApp Management Plan, please see
Chapter 6, Section 6.5.6. Among this plan is a new initiative to promote electrification of the RideApp fleet
serving Logan Airport.
2.2.3.3 Long-Term Parking Management Plan
Logan Airport’s parking supply, pricing, and operations are managed to promote the use of HOV, transit,
and RideApp options as well as to reduce drop-off and pick-up modes, which generate up to four vehicle
trips instead of two and higher emissions. Chapter 6, Section 6.5.7 provides additional updates on the
evolving implementation of ground access strategies.
2.2.3.4 Noise Abatement and Sound Insulation
Massport’s comprehensive noise abatement program includes the implementation of flight tracks
designed to optimize over-water operations, especially during nighttime hours, runway restrictions for
noisier aircraft, and noise-reducing ground run-up procedures. Massport has one of the nation’s oldest

residential and school sound insulation programs for those eligible under federal guidelines; to date,
Massport has provided sound insulation for a total of 36 eligible schools and 11,515 residential units with
investments of over $170 million towards these efforts, and Massport will continue to seek funding to
provide mitigation for eligible properties whose owners have chosen to participate. Massport also
operates a dedicated Noise Abatement Office with a state-of-the-art Noise and Operations Monitoring
System (NOMS).
In response to advocacy efforts by elected officials and Massport, for
the first time, the FAA will allow eligible homes treated prior to 1993 to
be treated again under the sound insulation program. 12 In 2022,
Massport was approved by the FAA for an initial grant to fund the
beginning phase of a new Residential Sound Insulation Program (RSIP).
Appendix I, Noise Supporting Documentation contains data on the
residential buildings, dwelling units, and schools that have been sound
insulated by Massport.
In June 2022, Massport and FAA concluded work with the Massachusetts Institute of Technology (MIT) to
identify opportunities to reduce noise through changes to performance-based navigation (PBN) systems,
including area navigation (RNAV). This was a first-in-the-nation project between the FAA and an airport
operator to better understand the implications of PBN and evaluate strategies to address community
concerns about aircraft noise. Massport continues to coordinate with the CAC, FAA, and MIT on additional
targeted technical questions and reviews. Massport is working with the FAA’s Aviation Sustainability
Center (ASCENT) on research projects concerning aircraft noise, flight procedures, and air quality
monitoring related to ultrafine particles (UFPs) . These efforts and progress towards achieving noise
reduction goals and UFP air quality monitoring can be found in Chapter 7, Noise , Section 7.4, and
Chapter 8, Air Quality and Greenhouse Gas Emissions , Section 8.3.1.4, respectively.
2.2.3.5 Air Emissions Reduction
Massport is a national leader in studying, tracking, and reporting on the air quality environment of Logan
Airport and implementing measures to reduce emissions. Initiatives include a commitment to sustainable
design with all Massport capital projects; operating the state’s seventh largest transit system (Logan
Express); providing pre-conditioned air (PCA) and 400 Hertz (Hz) power at aircraft contact gates to reduce
aircraft idling; and operating one of the largest privately operated, publicly accessible, compressed natural
gas (CNG) stations in New England. More information can be found in Chapter 8, Section 8.6.

2.2.3.6 Alternative Fuel Vehicles (AFV) Program
Massport established a vehicle procurement policy in 2006 that requires consideration of AFVs when
purchases are made. The Alternative Fuel Vehicles Program is designed to replace Massport’s
conventionally fueled fleet whenever feasible with alternatively fueled or powered vehicles to help reduce
emissions associated with Logan Airport operations. Massport now operates more than 100 vehicles
powered by gasoline-electric hybrid, diesel-electric hybrid, CNG, propane, flex fuel, and plug-in electricity.
More information can be found in Chapter 8 , Section 8.5.
2.2.3.7 Electric Ground Service Equipment (eGSE)
Massport is facilitating the replacement of gas- and diesel-powered ground service equipment with
electric GSE (eGSE) , if commercially available. In 2020, Massport was awarded an FAA Voluntary Airport
Low Emission (VALE) Program grant for charging infrastructure at Terminal E and installing 10 eGSE
charging stations at Signature Aviation Building 14.
2.2.3.8 Energy Planning
Massport has a long-standing energy management program committed to supply-side wholesale energy
management and procurement, and demand-side energy efficiency and renewable energy development.
Supply-side wholesale purchasing is managed through an interdepartmental advisory group consisting of
representatives from Massport’s Administration and Finance, Building Operations, Capital Programs
Department, and the Environmental Affairs Department. Procurement is guided by a Massport
Board-approved Energy Hedge Policy. Demand management is through individual capital projects and
stand-alone measures, where feasible, including investments in high-efficiency lighting and equipment
and automated building energy management and control systems. Renewable energy planning has
included a Massport-wide evaluation of feasible, third-party financed, renewable energy development
sites designed in coordination with the Commonwealth of Massachusetts Solar Massachusetts Renewable
Target Program (SMART). As part of this evaluation, all Massport properties were considered for potential
solar development.
Massport will continue to evaluate renewable energy development potential across all its properties.
Massport has existing self-financed solar panel installations at Logan Airport, including locations on top of
Logan’s Economy Garage, Terminal B Garage, Rental Car Center, Terminal A, and the Terminal C Canopy.
Previously, Massport formed a public-private partnership to develop its largest existing 357 kWh solar
installation on the roof of Terminal A and associated satellite buildings, which was part of a statewide
solicitation to facilitate American Recovery and Reinvestment Act (ARRA) grant funding for solar energy.

2.2.3.9 Open Space and Airport Edge Buffers
Over the last two decades, Massport has developed an extensive open space program to enhance
surrounding communities with more than $25 million invested towards the planning, construction, and
maintenance of four airport edge buffer areas and two parks along Logan Airport’s perimeter. Today,
approximately 40 acres of green space are developed or managed by Massport in partnership with the
East Boston community and as a response to engagement with the community. Massport also
collaborates in East Boston's open space planning through meetings with other agencies, including the
Massachusetts Department of Transportation (MassDOT), the City of Boston, and the MBTA.
Piers Park II broke ground on October 14, 2022, and was completed in
December 2023, adding approximately 4.5 acres of green space to the
East Boston waterfront. Sustainable elements of the Phase II design
included:
 Elevating the park site and creating landscape berms to provide
flood protection;
 Replacing the current gravel lot with 4.5 acres of green space and
planting 80 new trees;
 Installing drinking fountains with bottle filling stations;
 Placing energy-efficient lighting throughout the park and at the
new Sailing Center building, and;
 Building a highly efficient heating and cooling system in the new Sailing Center building. 13
