INTRODUCTION
A Message From 
Our President 
and CEO
At Armstrong World Industries (AWI), we are committed to 
driving positive change for a healthy world, starting with 
the built environment. To meet this commitment, we have 
developed a robust sustainability program that addresses 
our operations, while also seeking to help building owners 
and occupants achieve their own sustainability goals. Our 
commitment and the work we do in these areas align with 
our history of innovation and customer focus, as well as 
with our company purpose to make a positive difference 
in the spaces where we live, work, learn, heal and play.
The last several years have demonstrated that the need 
for healthy indoor environments has never been greater. 
At Armstrong, we understand that the ceilings and walls that 
surround us are essential links to our health and well-being. With 
people spending nearly 90% of their time indoors, we believe it 
is more important than ever to shape this experience positively. 
Together, the three pillars of our sustainability program—
Product, Planet and People—help us identify and address 
the challenges and opportunities ahead. In this 2023 report, 
we update our progress within the pillars toward our 2030 
targets and highlight key initiatives and achievements.
Our commitment to sustainability means working to minimize 
the impacts of the built environment to our existing natural 
world. Given that nearly 40% of global emissions come from 
buildings, our goals prioritize the protection of the environment 
for future generations. This includes our 2030 greenhouse 
gas (GHG) reduction targets that the Science Based Target 
Initiative (SBTi) approved in 2022. We are also making 
investments throughout our operations to increase efficiency 
and reduce reliance on nonrenewable resources. As of the 
end of 2022, we had reduced our carbon footprint by 13% 
from 2019 levels and increased our use of renewable 
electricity to 13% of total usage. 
We are also investing in sustainable and circular design 
practices to reduce the environmental impact of the products 
and solutions we provide. By reducing our reliance on finite 
resources, minimizing waste and pollution, and designing 
resilient infrastructure that can adapt to our planet’s changing 
needs, we have the potential to meaningfully contribute 
to the shift from a linear economy to a circular economy. 
We continue to pursue increased product transparency 
and to expand our SUSTAIN® portfolio of products that meet 
the industry’s most stringent sustainability criteria. We are 
also proud of our long-standing Ceilings Recycling Program. 
Since 1999, we have diverted over 1.2 million tons of virgin raw 
material from landfills. We continue to drive circularity in our 
operations, with customers and throughout our value chain. 
We are also innovating to support greater building efficiency. 
A key highlight is the development of an energy-saving 
system that combines the DynaMax® grid systems for data 
centers with our ULTIMA® AIRASSURE® gasketed ceiling. In 
2022, we validated that these systems installed in data center 
environments can deliver energy savings of up to 40 cents 
per square foot each year. With the average data center being 
100,000 square feet and reaching 1 million square feet for 
mega centers, the magnitude of savings is significant.  
We also know that healthy spaces and healthy communities 
go hand in hand. Our commitment to health and safety begins 
within our own walls and extends to the communities we serve. 
By investing in local organizations and community service 
projects, we can give back to the communities that have 
helped us grow and cultivate lasting partnerships that seed 
a sustainable future. In 2022, we further empowered our 
people to give back through an expanded employee match 
program for both charitable giving and volunteer hours. 
At Armstrong, we remain committed to driving positive change. 
Our sustainability efforts are a testament to our company’s 
values, and we are proud of what we have accomplished over 
the last year. 
I invite you to explore our Sustainability Report to learn more 
about our progress and plans for the future. Together with our 
stakeholders, we can take bold steps toward a healthier, more 
sustainable world for generations to come.
Sincerely,
Vic Grizzle
President and CEO

Getting to 2030
Healthier Learning 
Spaces for Panther Valley
Research shows that indoor environments with 
improved air quality, lighting and acoustics help 
children learn more. Even small changes can 
make a significant difference in test scores. 
Awair indoor environmental sensors installed 
throughout Panther Valley Elementary School 
in Nesquehoning, Pennsylvania, identified 
concerns for air-quality, noise and light-levels.
The school replaced their existing ceilings with 
new ceiling tiles that absorb 75% of the sound 
that strikes them, and with new LED light fixtures 
that more than double light levels. Air-cleaning 
solutions installed in the ceilings capture and 
remove 90% of airborne contaminants and 
allergens. The resulting Awair scores indicate 
significant improvements—echoed by glowing 
reviews from teachers and staff.

Healthy spaces start with sustainable sources. We’re working to fully understand the broad impacts of our supply chain as we seek ways to 
contribute to a healthier environment within the life cycle of our products. This includes monitoring and eliminating chemicals of concern 
across our full product portfolio and providing transparent disclosure of potential health and environmental impacts of our products.
Free of Chemicals of Concern
The building products industry has made strides in recent years to 
remove and reduce the use of harmful chemicals that pose both 
health and environmental risks. To reach our goal of eliminating all 
chemicals of concern in our products by 2030, we take a holistic 
approach to chemicals and consult various sources to identify 
hazards and find safer alternatives. Our commitment must be 
ongoing. As we innovate our products and acquire new capabilities 
through acquisitions and partnerships, we remain vigilant in tracking 
and monitoring new potential chemicals of concern as knowledge 
and research progress. We work closely with our suppliers and 
partners to reduce exposure and minimize environmental impacts.
•	 SUSTAIN® products meet the industry’s stringent sustainability 
standards, offer material ingredient transparency to 100ppm level, 
and are free of Living Building Challenge® red list chemicals. 
•	 Across our Architectural Specialties product lines and their 
supply chains, we are making progress on identifying chemicals of 
concern and toward achieving full material transparency.  
Leading With Transparency
Transparency is a fundamental principle that guides our approach 
to sustainability. We believe that to create healthier spaces, it’s 
crucial for stakeholders to have access to reliable information on 
the potential impacts of our products. This includes transparent 
disclosure of potential health hazards or environmental effects 
through product labeling and participation in third-party certification 
programs. We take our responsibility seriously and conduct product 
life cycle analyses, which allow us to identify and manage any 
potential impacts of our products—from development to end of life.
•	 Our search tool for sustainable products makes it easy to find 
products that meet the most stringent sustainability criteria 
and helps customers more easily adopt low-carbon, 
sustainable solutions.
See our full list of transparency documents.
Building a More Sustainable Supply Chain
By implementing sustainable practices at each step of our supply 
chain, we’re working to minimize our environmental and social 
impacts, including mitigating potential impacts on human rights, 
labor and corruption, and encouraging a proactive response to 
climate change, deforestation and biodiversity crises. Most of our 
suppliers are in North America, and U.S.-produced Mineral Fiber 
products account for 90% of our raw material sourcing.
We are working to increase collaboration with our suppliers, 
improving our ability to partner with smaller suppliers and 
updating our supplier screening criteria and audit processes 
to ensure sustainable practices.
•	 We expect all our suppliers to adhere to our Supplier Code 
of Conduct.
•	 Our Conflict Minerals Policy outlines our aim to avoid knowingly 
buying conflict minerals that contribute to human rights abuses 
in conflict-affected regions.

As the impacts of climate change intensify and the global waste problem worsens, we believe 
companies have a critical responsibility to adopt more sustainable systems of production, reuse and 
recycling. We’re working to close the loop by designing waste and pollution out of our processes 
and repurposing existing products to reduce our consumption of natural resources. 
The centerpiece of our circular economy effort is our Ceilings Recycling Program—the nation’s first 
recycling program that encourages customers to return their ceiling tiles at the end of life to be 
recycled into new products. Since 1999, the program has diverted over 216 million square feet of 
discarded ceiling materials from landfills. 
Use our diversion savings calculator to learn more.
How We’re Accelerating Our Circularity Efforts:
•	 Helping customers collect end-of-life ceiling tiles
•	 Identifying new products that can integrate more recycled materials
•	 Partnering with organizations, such as the Ellen MacArthur Foundation, to find new opportunities 
for recycling and reuse across our product lines, and with organizations such as ASTM International 
to standardize recovery rate formulas for end-of-life product measurement
For more on our circular economy efforts within our manufacturing process, see the Healthy Planet
section of this report.
Steps to a 
Circular Future
Sustainable headquarters 
and waste diversion 
for TSP
The Sheward Partnership (TSP), one of the 
country’s leading architectural design and 
sustainability consulting firms, was committed 
to integrating sustainability into every aspect 
of the design of its new 9,150-square-foot 
Philadelphia, Pennsylvania, headquarters. 
An employee survey also revealed that 
acoustics had been an issue in the old space. 
TSP addressed both requirements with three 
high-performance, sustainable ceiling systems 
from the Armstrong® SUSTAIN® portfolio.
Diverting construction waste away from 
landfills was another goal. By recycling the 
old ceilings through the Armstrong Ceiling 
Recycling Program, the waste contributes 
to TSP’s pursuit of the LEED v4 MR credit 
for Construction and Demolition Waste 
Management and the Living Building 
Challenge® Imperative credit for Net Positive 
Waste. The total diverted weight of old ceiling 
tiles to Armstrong was 1.68 tons, contributing 
toward the project’s overall diversion rate 
of 83.7 percent.
Our Ceilings Recycling Program has saved
1.2 million+ tons
of virgin raw materials—enough to cover 
Central Park six times.

Tackling Embodied Carbon
The building industry contributes to nearly 40% of the world’s carbon emissions and requires bold changes to significantly 
reduce its environmental impact. Embodied carbon is the emissions generated during the life cycle of building materials: 
extraction of raw materials, processing, transportation, manufacturing and disposal or recycling. This carbon is one of the 
most significant drivers of carbon emissions in buildings and one of the most overlooked.
The World Green Building Council’s pioneering report, “Bringing Embodied Carbon Upfront,” outlines a coordinated action 
for the building and construction sector to tackle embodied carbon. This bold new vision states:
“By 2030, all new buildings, infrastructure 
and renovations will have at least 40% less 
embodied carbon with significant upfront carbon 
reduction, and all new buildings are net zero 
operational carbon.
“By 2050, new buildings, infrastructure and 
renovations will have net zero embodied 
carbon, and all buildings, including existing 
buildings, must be net zero operational carbon.”
To reach our 2030 goals, we are constantly improving the efficiency of our operations across the company. We continue to 
make strides in demonstrating reduced carbon emissions for many of our products in our Environmental Product Declarations, 
which show the environmental impacts over the full product life cycle.
Reduction in Water Intensity of Our Products
We are evaluating and creating a plan to reduce water intensity in our products and are exploring alternative materials that 
reduce water consumption. We have also been developing a plan to track water intensity in our manufacturing operations, 
looking at gallons per square foot.
Reducing Our Carbon 
and Water Footprint
Cool Temperatures 
(and Savings) for 
Data Centers
As demand for data centers continues to surge 
across the country, their energy consumption 
has become a growing threat to sustainability. 
The constant need for power and cooling in 
these data centers is significantly straining the 
environment. To address this challenge, our 
team went heads down in 2022 to develop 
a sustainable solution—a new product 
combination specifically designed to 
control heat and airflow.
Our Mineral Fiber ULTIMA® AIRASSURE® ceiling 
panels are engineered to self-seal into the 
DynaMax® ceiling suspension system, reducing 
airflow leakage and improving overall facility 
energy efficiency. This product combination 
has the potential to keep data centers cooler 
while delivering significant energy savings 
of up to 40 cents per square foot each year. 
Typically, suspended ceilings are associated 
with a high leakage rate—up to 2.0% for total 
heating, ventilation and air conditioning (HVAC)
system flow. AIRASSURE with DynaMax ceilings 
reduce the bypass leakage to below 0.5% of 
total HVAC system flow.
In 2022, we achieved a
13%
decrease in carbon emissions 
compared with a 2019 baseline.

optimize panels within a ceiling layout based on realistic 
scrap reusability, reducing material waste and the 
environmental impact of a project. In 2022, ProjectWorks 
automated this optimization for Axiom perimeter trim 
to increase sustainability at the manufacturing level. 
Since Axiom is pre-cut based on job specific conditions, 
ProjectWorks started optimizing trim schedules for the 
manufacturing plant by finding the most efficient cut order 
that yields the least amount of scrap trim possible. 
ProjectWorks’ advanced technology can also generate 
the location and quantity of every part required to install 
the ceiling project. This provides a more efficient and 
accurate way for customers to specify projects. That 
means less guesswork—and less waste.

Getting to 2030
Marietta Plant Honored With 
2022 Sustainability Award for 
Energy-Saving Project
At our Marietta, Pennsylvania, plant, process engineer 
Jeff Dunning and Maintenance and Reliability project 
manager Kyle Swift led a project to reduce vacuum 
pump failures and downtime due to calcium carbonate 
buildup in water pumps used for manufacturing Mineral 
Fiber ceiling tiles. This project resulted in $300,000 
in annual energy savings and earned Marietta a 2022 
Sustainability Award from Solenis.
The Solenis Sustainability Award recognizes projects 
that reduce water and energy use, improve carbon 
footprint, minimize waste or optimize the use of raw 
materials. The plant project team collaborated 
with Solenis to implement a new, energy-efficient 
vacuum pump scale control system. This led to a 
2% reduction in electric current, resulting in less 
scale buildup, and enabled the pumps to achieve 
the same level of vacuum with less energy. Projects 
like these are a critical part of achieving our healthy 
planet sustainability goals.

Carbon Footprint
With the growing impact of climate change, our planet is experiencing 
more severe conditions. As droughts, fires and rising sea levels persist, we 
acknowledge the urgency of the situation and the need for collaborative 
action to preserve Earth’s resources. 
We’ve set ambitious goals to reduce our Scope 1 and 2 GHG emissions 
by 30%. Our road map to reaching this target includes:
•	 Achieving reductions through operational efficiency and product 
design improvements  
•	 Reducing emissions from natural gas combustion by upgrading to 
more efficient manufacturing equipment
•	 Exploring renewable electricity options where we operate, while 
expanding our portfolio of renewable energy options
Our commitment to reducing emissions has been validated by the SBTi, 
whose science-based targets help companies establish a clear roadmap 
for reducing emissions. The SBTi reviews and approves these targets 
based on rigorous criteria. At Armstrong, our contributions are on track 
to limit global warming to well below the 2°C target.

Circular Systems
As the world increasingly recognizes the environmental and economic challenges of our linear 
“take-make-dispose” model, the need for a more sustainable and circular approach to manufacturing 
becomes increasingly urgent. At Armstrong, we’re working to design waste out of our value chain, 
help our customers and end users do the same, and unlock economic opportunity.
Reducing Waste, Maximizing Resources
According to the U.S. Environmental Protection Agency, construction and demolition account for 
nearly a quarter of the U.S. waste stream. By creating circular systems in manufacturing, we can 
move toward a more sustainable future, where waste is minimized, natural resources are conserved 
and products are designed to be reused, repaired and recycled.
How We’re Getting There:
•	 Offering high-quality products designed for long-term use
•	 Recycling waste generated during production back into the manufacturing process
•	 Using recycling streams such as pre-consumer fiberglass and mineral wool
•	 Enhancing our Ceilings Recycling Program to bring more used ceilings back 
to make new products
•	 Incorporating post-consumer recycling streams—such as newspapers, 
telephone books and water bottles—to reduce the use of virgin materials
•	 Pursuing innovative partnerships that enable more sustainable supply chains

Doubling Our Impact
The AWIF awarded its 2022 Better Building Grants to four nonprofit 
organizations to support capital campaign projects. Two of these 
community grants focus on major facility renovations, and two provide 
maintenance funding to past Better Building Grants recipients to 
keep their facility in good working order. These renovation grants 
also included product donations from AWI.
Renovation Grants: 
Lancaster Public Library grant will help fund the library’s capital 
campaign to raise more than $10 million to complete its move to 
a new location in downtown Lancaster, Pennsylvania. Armstrong 
ceilings and acoustical wall panels will be incorporated into the new 
design to allow for better acoustics in common areas of the library, 
including the staircase, children’s library, young adult library and 
common reading space.
Schreiber Center for Pediatric Development is adding 14,000 
additional square feet to its West Lancaster, Pennsylvania campus. 
The expansion includes 20 rooms—eight for physical therapy and six 
for behavioral health treatment—that will reduce the current waiting 
list for treatment. 
Schreiber Pediatric, which has been in operation for 86 years 
and serves over 4,000 children annually, offers therapy services 
to children with physical, learning and behavioral disabilities. 
No family is ever turned away because of an inability to pay.
Maintenance Grants:
In July 2021, the Lancaster Cleft Palate Clinic completed the renovation 
of its 61-year-old building and welcomed patients to brighter, quieter 
and healthier interior spaces made possible in part with AWI product 
donations. The 2022 AWIF grant was used for general building 
maintenance and upgrades.
Lancaster Early Education Center’s building is more than 100 years 
old. Its exterior steps leading to the playground were brought up to 
code and adapted to the mobility of very young children. The AWIF 
maintenance grant funded the renovation of the steps.
In addition to funding Better Building Grants, AWIF also donates to 
our various production sites to support the organizations making a 
difference in their local communities. Organizations supported in 
2022 include the following: 
•	 Broadway Youth Center in Chicago, a Howard Brown Health 
clinic providing LGBTQ+ health and social services
•	 Mid-Ohio Food Collective
•	 Together We Grow Community Gardens in Licking County, Ohio
•	 Ozarks Food Harvest in southwest Missouri
•	 Community Foundation of Jackson County in West Virginia
•	 Family Promise of Escambia County, a northern Florida organization 
supporting families experiencing homelessness
Along with AWIF, we help enable economic empowerment through 
our continued partnerships with organizations like United Way that 
strive to make a positive difference in the lives of those in our 
communities. Five of our larger locations hold annual United Way 
campaigns, and for the 2021–2022 giving season, our employees 
contributed more than $150,000.  
Supporting Employee Giving
We support our employees’ efforts in their local communities 
through our Employee Choice Match program, our donation-matching 
initiative that enables employees to direct funds to qualifying 
non-profit organizations they are passionate about. In 2022, we 
made several enhancements to this program, including introducing 
an easy-to-use portal for accessing matching funds. Through the 
new and more accessible platform, employees donated more money 
overall and supported more organizations. 
Through our Dollars for Doing program, Armstrong also offers financial 
matches for volunteer time. This is in addition to the annual funds 
provided to each of our locations from the Company and the AWIF 
to support a community cause of its choosing.

About This Data
We have prepared this report in accordance with the GRI Standards, Core option. We have also aligned our reporting 
with the following frameworks and standards: Sustainability Accounting Standards Board (SASB), Construction Materials 
standards and the Task Force on Climate-Related Financial Disclosures. This report also serves as Armstrong World 
Industry’s United Nations Global Compact Communication on Progress. We have also provided a submission separately 
through our involvement in the UN Global Compact Early Adopter Programme.
Forward-looking statement
Our Sustainability goals, KPIs, projects, plans, targets and expectations are long-term, directional and aspirational, and, 
by their nature, include forward-looking statements as such term is defined in Section 27A of the Securities Act of 1933, 
as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and such statements are intended 
to be covered by the safe harbor provided by the same. Statements of aspiration, future events or conditions, including 
forward-looking statements, are sometimes identified by the words “will,” “should,” “intend,” “expect,” “estimate,” “believe,” 
“could,” “project,” “target” or other similar words or expressions. Forward-looking statements in this document may include, 
but are not limited to: statements regarding our sustainability goals, KPIs, projects, plans, metrics, affiliations, pledges, 
commitments and strategies. By their nature, they are based upon current plans, estimates and expectations that are 
subject to risks, uncertainties and assumptions. As such, no guarantees or assurances are made that they will be achieved 
or successfully executed. Additionally, the Sustainability data, statistics and metrics included herein, unless otherwise 
specifically indicated, are non-audited estimates, were not prepared in accordance with U.S. generally accepted accounting 
principles (GAAP), apart from limited external assurance on 2019 and 2022 Scope 1 and 2 GHG emissions, have not 
been externally assured, continue to evolve and may be based on assumptions believed to be reasonable at the time of 
preparation, but should not be considered guarantees. Except to the extent required by applicable law, we undertake no 
obligation to publicly update or revise any forward-looking Sustainability statement, whether as a result of new information, 
future events or otherwise. Our Sustainability reporting may also use certain terms, including those that the GRI Guidelines 
or other reporting formats refer to as “material” topics, to reflect the issues of greatest importance to us and our stakeholders. 
Used in this context, these terms are distinct from, and should not be confused with, the terms “material” and “materiality” 
as defined by or construed in accordance with securities law or as used in the context of financial statements and reporting.

Our Governance (Continued)
Ethical Policies and Practices
Across every aspect of our business—including our Operating 
Principles, Code of Business Conduct, subject-specific policies, 
culture of compliance and open communication—we maintain high 
ethical standards and ensure that our employees uphold them.  
Comprehensive Compliance Oversight
Any allegations of noncompliance with our policies and Code 
of Business Conduct are investigated and tracked by the Office 
of Compliance. To ensure policies reflect current law, a Company 
Compliance Committee, composed of representatives from various 
business segments, regularly reviews corporate policies to ensure 
compliance with current laws. All complaints and concerns that 
our Compliance Team receives are regularly reported to the 
Audit Committee. 
Investing in Compliance Training
All employees receive Code of Business Conduct training on 
workplace behavior, including anti-harassment. Employees in 
sensitive areas also receive anti-corruption and/or antitrust training. 
Our Compliance Team continuously pursues industry developments, 
and we host regular employee refresher courses to uphold current 
best practices.
Acquisitions
Any companies we acquire undergo a rigorous due diligence and 
risk assessment process before they’re integrated into our regular 
training cycle on ethical behavior. 
Political Engagements
We comply with all legal requirements related to lobbying activities 
and obtain approval from the Legal Department before contributing 
any funds or resources to political candidates or parties. 
Protecting Privacy
We take compliance with privacy laws seriously and have strict 
policies to collect, process, transfer, handle and access personal data 
for our employees, customers and stakeholders. We also conduct 
regular staff trainings and perform risk assessments for third-party 
cloud providers to ensure that they meet our high standards for data 
privacy and protection. See our Privacy Policy. 
Safeguarding Against Cyber Threats
As cybersecurity rapidly evolves, so do our safeguards. We have 
a comprehensive cybersecurity program that includes detailed 
policies, educational tools and a dedicated Incident Response 
Team. We also hold regular awareness events as an ongoing 
prevention measure. Learn more on page 23 of our 2022 report.
