WEYERHAEUSER CO

Sustainability has been one of the core values of our company for nearly 100 years. We have spent decades building a solid foundation characterized by excellence in environmental stewardship, social responsibility and corporate governance. Maintaining a strong ESG foundation is a key component of our ability to drive long-term shareholder value, and these principles guide us in how we conduct our business every day.

ENVIRONMENTAL STEWARDSHIP

As a pioneer in sustainable forestry, we have environmental stewardship deeply rooted in our business and very much at the core of our company. To operate successfully, we need our forests to provide a sustainable supply of wood fiber now and long into the future. To ensure our forests remain healthy and valuable for decades to come, we protect and enhance the many additional benefits they provide, such as clean water, clean air and critical areas for biodiversity. We also enhance the environmental footprint in our wood products manufacturing business, including reducing air emissions, minimizing waste and maximizing wood recovery. These actions are prudent for our business, good for the environment and essential to how we run our operations sustainably.

PRACTICING SUSTAINABLE FORESTRY

As one of the world’s oldest and largest private timberland owners, we’ve been growing, harvesting and regrowing forests for more than a century. We have been managing our forests sustainably for a very long time. We advocated for legislation in 1925 to encourage reforestation after harvest, which was an uncommon practice at the time. In 1937, we began research into sustainable yield forestry, which ensures harvesting does not diminish a forest’s ability to provide the same volume in the future. In 1938, we were one of the first companies to plant tree seedlings, and in 1941 we established the first certified tree farm in the U.S. We harvest, on average, only two percent of our forests each year, and 100 percent of our timberlands are reforested after harvesting. We plant more than 100 million tree seedlings per year, about 190 trees per minute throughout the year.

CARBON RECORD

Our carbon record shows that our net impact is significantly carbon negative, meaning we remove substantially more carbon from the atmosphere than we emit each year.

In 2023, our scope 1 carbon emissions were 0.4 million metric tons of carbon dioxide equivalent (mtCO 2 e), primarily attributable to fuel usage within our wood products mills and fertilizer application in our timberlands. Also in 2023, our location- and market-based scope 2 emissions were 0.5 million and 0.4 million mtCO 2 e, respectively, which are emissions from the energy we purchase. Our scope 1 and scope 2 emissions are calculated in accordance with the Greenhouse Gas Protocol's Corporate Accounting and Reporting Standard. We obtained limited assurance of our 2023 scope 1 and scope 2 emissions from a third-party attestation provider.

In 2023, our scope 3 emissions totaled 9.3 million mtCO 2 e, primarily generated by customers who purchase our wood fiber and the end-of-life emissions of the products we sell. Our scope 3 emissions are calculated in accordance with the Greenhouse Gas Protocol's Corporate Value Chain (Scope 3) Accounting and Reporting Standard.

Our sustainably managed forests play a critical role in helping to mitigate climate change. As our millions of acres of forests grow, they absorb carbon dioxide from the atmosphere and store it in their trunks, limbs and roots, as well as in the soil. In 2023, our direct carbon removals totaled 9 million mtCO 2 e (the increase in above-ground carbon in our U.S. timberlands attributable to forest growth and management practices after we account for harvest and mortality). Also in 2023, the indirect carbon removals across our value chain were 29 million mtCO 2 e (primarily carbon stored in our own long-lived wood products and products that our customers make from our logs).

In 2023, our forests contained between 2.3 billion and 3.6 billion mtCO 2 e. Approximately 1.0 billion mtCO 2 e was stored in our trees and roots, and an additional 1.3 billion to 2.6 billion mtCO 2 e was stored in soil and other biomass. After our trees are harvested, much of their carbon remains stored in the long-lived wood products made from them for the life of those products. After harvest, we plant millions of new trees, which then begin absorbing more CO 2 from the atmosphere, and the next round of wood products store more carbon yet again. Our managed forests also provide other climate benefits. They mature more quickly and are able to bank more carbon through faster, continuous rotations, all while maintaining the vast pool of carbon in the forest soil. In addition, using wood for construction requires less energy and results in fewer greenhouse gas (GHG) emissions compared with other building materials, such as steel and concrete.

We have a near-term science-based GHG emissions reduction target that has been approved by the Science Based Targets initiative at the most ambitious level, in alignment with the Paris Agreement goal of limiting global warming to 1.5 degree Celsius. Our target includes a commitment to reduce our scope 1 and 2 emissions by 42 percent overall, and our scope 3 emissions by 25 percent per ton of production, both by 2030, measured against a 2020 baseline. We are also members of The Climate Pledge, a commitment to achieve net-zero carbon emissions across our value chain by 2040. We expect to achieve these targets primarily through energy efficiency projects, increased renewable energy usage and supplier engagement. As companies across our value chain actively work to reduce their emissions, with many already taking action or making commitments, we expect our scope 3 emissions to decrease over time.

MAKING BETTER ENERGY CHOICES

We are members of the U.S. Department of Energy's (DOE) Better Plants Program, which includes a goal to improve purchased energy efficiency at our manufacturing facilities by 10 percent between 2020 and 2030. This partnership requires us to adopt a companywide goal to improve energy efficiency, annually report our progress to the DOE and develop an energy management plan. We have a comprehensive wood products energy strategy that we have begun implementing by developing short-term action plans, evaluation tools and energy champions at all sites. We also fully integrate GHG and energy metrics into capital planning processes and conduct energy audits at manufacturing sites. On average, we meet more than two-thirds of the energy needs in our manufacturing facilities from renewable biomass by using what would otherwise be wood waste from mill manufacturing residuals. This approach allows us to reduce our reliance on nonrenewable fossil fuels and purchased electricity. We also support other renewable energy solutions, such as wind and solar power, through our timberlands. In addition, we also supply other mills, companies and utilities with woody biomass that is used to produce renewable, carbon-neutral energy.

PROTECTING BIODIVERSITY

The forests we manage host hundreds of native vertebrate species, including large mammals such as deer, elk, cougar, black bear and bobcat, as well as a tremendous diversity of birds, reptiles, amphibians, insects, native fish and other aquatic species. Many of these species prefer different forest age classes and forest structures, or other habitat features on the landscape, such as riparian areas. Since our timberlands contain a matrix of forest stand ages, along with other special areas we protect around streams and wetlands, these forests support a high level of native biodiversity. To preserve and protect this balance, we regularly conduct biodiversity assessments across our forests as part of our ongoing stewardship and forest management operations. These assessments include analyzing species occurrence data and assessing the presence of threatened, endangered, critically imperiled, imperiled and other regionally significant species. Conducting biodiversity assessments across our land base gives us necessary insights to help design and implement best practices for habitat conservation and species protection throughout the course of our forest management activities. These practices include leaving buffers along riparian areas, surveying sites for species occurrences prior to harvesting and thinning activities, managing for specific habitat using prescribed burns or thinning harvests and refraining from harvesting during certain sensitive times.

IMPROVING CONSERVATION OUTCOMES

Ensuring our forests provide habitat features that support at-risk, sensitive or threatened and endangered species is a core component of our environmental stewardship. We pursue a number of programs to create and preserve critical habitat, including partnering on conservation easements and agreements, formal Habitat Conservation Plans (HCPs) with the U.S. federal government and mitigation banking. Conservation easements and other local agreements can assure sustainable forest practices and the long-term stewardship and protection of wildlife habitat, biodiversity and recreational access. These partnerships can be made with a variety of groups and organizations, and they allow natural resource management to continue, which helps protect the economic benefits of a working forest. We work with more than 20 different conservation partners across the U.S. to develop programs to expand public access, protect critical habitat and preserve sites of environmental, cultural and historical significance. HCPs are administered under the federal Endangered Species Act and help provide more specific guidance on the protection and enhancement of habitats for threatened and endangered species. We participate in more than 50 conservation agreements and collaborative efforts that address specific habitat needs of at-risk or sensitive species across our timberlands. Authorized through the U.S. Clean Water Act, mitigation banking allows us to set aside certain areas of our timberlands to preserve, enhance or restore a wetland, stream or habitat area to make up for development by another entity in a similar nearby ecosystem. Mitigation banks are regulated and approved by the U.S. Army Corps of Engineers and a consortium of federal, state and local agencies. We currently operate 16 mitigation banks and projects, primarily in the U.S. South. Several other projects are in various stages of evaluation and development and we are always looking for new opportunities and partnerships to expand our impact.

CONTRIBUTING TO CLEAN WATER

Our forests are critical for providing clean water to communities in our watersheds. The trees, plants and soil absorb rain and snowmelt, allowing our forests to capture and slowly release clean water into the many streams, rivers and groundwater systems on our lands. Our sustainable forestry practices help us maintain our forests' ability to capture and filter water, ensuring our harvesting methods safeguard water quality for people, fish and countless other organisms. Because our forests rely on rainwater to grow, our company’s measurable impact on water use is limited to our Wood Products manufacturing sites and offices, where water is either recycled or treated on-site, evaporated while products are drying or delivered to a local, publicly-owned treatment facility.

MINIMIZING WASTE

The primary products we produce are solid lumber, wood panels and engineered wood products. Wood shavings, sawdust, chips and bark are sold or delivered to downstream customers who make other essential products for society. Toilet paper, diapers, paper, cartons, boxes, bags, landscaping mulch and wood pellets are just a few of the countless products made from our wood fiber, as well as forest and mill by-products. We are always looking for ways to reduce the amount of waste we generate, including finding responsible methods for reuse and recycling. On average, 99 percent of our wood residuals are used to create other products or to generate energy.

VERIFYING WITH CERTIFICATION

To prove our forest management and wood fiber procurement practices are sustainable, we participate in independent certification programs for forest management, fiber sourcing and chain of custody. Our entire timberland portfolio is certified to the Sustainable Forestry Initiative® (SFI) Forest Management Standard. That compares with only 11 percent of the world's forests that are certified today (the vast majority of these certified forests are in the Northern Hemisphere). Internationally recognized forest certification standards, such as SFI®, Programme for the Endorsement of Forest Certification (PEFC), the American Tree Farm System®, and the Forest Stewardship Council®, provide customers and stakeholders with an objective, third-party determination of whether companies are implementing sustainable forestry practices and making products that come from legal and well-managed sources. We are vocal supporters of the importance of these standards and the use of independent, third-party audits to verify compliance and promote sustainable forestry around the world. At Weyerhaeuser, we choose to certify our timberlands and operations to SFI’s standards because they are strong, science-based standards that have effectively pushed forestry in a more sustainable direction. These standards are designed specifically for operations in North America, and we value SFI’s approach, especially around logger training and the requirement to invest in and apply research back into our operations. In addition to our forests, we certify all of our manufacturing facilities to the SFI Fiber Sourcing or Certified Sourcing standards, and select sites are certified to the SFI and PEFC Chain of Custody standards.

SOCIAL RESPONSIBILITY

Throughout our long history, social responsibility has been an integral part of how we do business. Our company needs diverse, talented workers to grow, innovate and thrive with us for decades to come. Because we depend on our people, we have a responsibility to create a safe, inclusive work environment where employees are proud to spend their careers. We also need strong communities around us, filled with people who trust and support our work.

OUR PEOPLE BY THE NUMBERS

In 2024, we employed 9,440 employees, including 8,077 in the United States,1,355 in Canada and 8 in Japan. Of these employees, 2,355 are members of unions covered by multi-year collective-bargaining agreements.

We will continue to closely monitor evolving best practices and will make adjustments to our approach as necessary and appropriate.

COMPANY CULTURE AND ENGAGEMENT

We consider our strong company culture to be a competitive advantage. We are intentional in our efforts to preserve the aspects of our workplace environment that make our company a great place to work, as well as continuously improve and evolve our culture. At the heart of our culture is an unwavering commitment to our core values — safety, integrity, citizenship, sustainability and inclusion. These values are cited often by our employees and are visible throughout our organization. We also embrace five key behaviors that shape our culture and guide how we work together — urgency, accountability, courage, simplicity and innovation. To assess the health of our culture, we conduct regular companywide surveys to collect candid feedback from employees and assess overall engagement. In 2024, we conducted an engagement survey of all employees and our response rate was 81 percent. Our overall engagement favorability score from this group was 86 percent and our average favorability score on questions about the strength of our values was 85 percent. Another indicator we monitor to assess the strength of our company culture is voluntary turnover, which was 10 percent in 2024 (down from 11 percent in 2023).

SUPPORTING OUR COMMUNITIES

We operate in rural communities across North America, and we are proud to invest our time and money to help ensure they are thriving places to live and work. In 2024, we provided $6.5 million in charitable grants, partnerships, matching gifts, research support and in-kind giving to our communities. We also announced the second community we are supporting through our THRIVE program, which involves a commitment to invest a total of $5 million across five of our operating communities that are most in need of support. Additionally, our employees volunteered over 23,000 hours of their time to causes they care about. Through our companywide employee giving platform, we provide an easy way for all employees to donate to charities using payroll deduction, and we offer company match programs for both employee donations and volunteerism hours.

PROMOTING ENVIRONMENTAL EDUCATION

Drawing on more than a century of experience in sustainable forestry, we share our story and expertise through tours of our forests and facilities across North America, and we also operate two centers that are open to the public and provide a range of experiential opportunities to learn about forestry, ecology and environmental issues. In Washington, our Mount St. Helens Forest Learning Center is full of exhibits that tell the story of Mount St. Helens and the return of the forest through interactive, hands-on activities and visual displays. In North Carolina, our Cool Springs Environmental Education Center offers a 1,700-acre working forest and outdoor classroom for visitors to explore forestry working in harmony with wildlife habitat, air quality, water quality and recreational activities.

STRONG GOVERNANCE

Our corporate governance practices and policies promote the long-term interests of our shareholders, strengthen the accountability of our board of directors and management and help build public trust in our company. Our governance framework is built on a foundation of written policies and guidelines, which we monitor and modify on a continuous basis to reflect changing best practices and legal requirements, as well as feedback from our shareholders. Following are summaries of some of our important governance practices.

BOARD COMPOSITION AND INDEPENDENCE

Our corporate governance guidelines and the listing requirements of the New York Stock Exchange (NYSE) require that a majority of the board be comprised of independent directors. Our current board composition far exceeds this requirement, as nine of our ten directors are independent, with the one exception being our chief executive officer. We have appointed eight new directors to our board since 2015. Four of our directors are women, including one woman of color, and two of our three key board committees are chaired by female directors. Our board chair and our chief executive officer are currently separate. Our board chair is an independent director, but to the extent the board chair were not independent, our Corporate Governance Guidelines require that the board appoint a lead independent director to preside over executive sessions of the independent directors and be responsible for communicating to management regarding any comments or concerns of the directors. We believe these governance structures provide effective monitoring and objective evaluation of the chief executive officer’s performance and support the board’s independent oversight of the company’s performance and governance standards. All of our directors stand for election annually, and we have a majority voting standard in uncontested elections. The board has regular executive sessions of independent directors, and the Audit, Compensation, and Governance and Corporate Responsibility Committees are all composed solely of independent directors in accordance with NYSE and SEC rules.
