WEYERHAEUSER’S ASSESSMENTREFERENCE

Area of forestland certified to a thirdparty forest management standard

We certify 100% of our owned, leased, and managed forestland in the United States and Canada to theSustainable Forestry Initiative (SFI) Forest Management Standard.

Environmental Stewardship –Certification

Area of forestland with protectedconservation status

We have formal habitat management agreements on 14.2 million acres of our land, which means
we commit to managing these lands to maintain species in their suitable habitat and natural geographic
distributions.

Our Data – Ecosystem Services

Area of forestland in endangered species
habitatWe measure and report the combined acreage of threatened and endangered species habitat on our land.
In 2021, this area was 29,300 acres across the U.S. and Canada. Read about how we manage our land forthese species on the regional forestry pages of our website.

Description of approach to optimizing
opportunities from ecosystem services
provided by forestlands

We measure and report on the ecosystem services provided by our forests.

Our Data – Ecosystem Services

Area of forestland in indigenous landOur owned and managed timberlands in the United States are private land, not considered to be
indigenous peoples’ land. We have long-term license agreements with the Canadian provincial
governments which grant us the timber rights and management responsibility for a defined area on which
we may operate to support one or more wood product manufacturing facilities.

Description of engagement processes
and due diligence practices with respect
to human rights, indigenous rights, andthe local community

We work proactively to build long term, successful and mutually beneficial relationships with Indigenous
peoples and describe this framework in detail on our website. As a part of our SFI Forest Management andFiber Sourcing certificates, we recognize and respect indigenous peoples’ rights, avoid fiber sourced
without effective social laws and meet the intentions of the ILO convention on human rights.

Description of strategy to manage
opportunities for and risks to forest
management and timber production
presented by climate change

Our climate-related impacts are identified by an internal cross-functional team of experts who areresponsible for assessing and managing climate-related risks and opportunities. We share details of theserisks and opportunities on our website, in our TCFD Alignment and in our annual response to CDP Climate.

Discussion of processes to assess and manage
risks and/or hazards associated with chemicals
in products

We focus company-wide on reducing chemical risk by using a comprehensive local
chemical-approval process, reducing the overall number of chemicals used in ouroperations, seeking less-hazardous substitutes for chemicals, and by use of acompany-wide safety database.

Wood Products – ProductStewardship & Safety Data Sheets
Product Stewardship PolicyPercentage of eligible products meeting volatileorganic compound (VOC) emissions andcontent standards

We are committed to providing online access to safety data sheets and correspondinglabels for all our manufactured wood products. 100% percent of our eligible wood
products meet VOC emissions and content standards.

Description of efforts to manage productlifecycle impacts and meet demand forsustainable products

Wood is a renewable and sustainable building material which consumes less energy, emits
fewer greenhouse gases, releases fewer pollutants and stores more carbon comparedwith other building materials like steel and concrete. Read about our efforts to manage
the lifecycle impacts and meet demand for sustainable wood products on our website.

Wood Products – Green Building

We do not consider either of these metrics to be material. We reuse, recycle or repurpose
99% of what could have been waste in our operations. Excluding material that is burnedfor energy, 70% of our mill by-products and waste are recycled or reused.
