VANCOUVER, BC, June 3, 2026 /PRNewswire/ - Today, West Fraser Timber Co. Ltd. ("West Fraser" or the "Company") (TSX and NYSE:WFG) released its 2025 Sustainability Report. The report highlights the Company's sustainability performance across a variety of environmental, social and governance goals and disclosed targets.

"Our 2025 Sustainability Report, Building Foundations for the Future, reflects our commitment to transparency and responsible operations, highlighting the progress we are making while identifying priority areas for further action to enhance our ability to succeed in a rapidly changing world," said Sean McLaren, President and CEO. "As we look ahead, we will continue embedding sustainability into every part of our company — improving performance, reducing risk and creating value for everyone who depends on West Fraser."

2025 key achievements highlighted in the report include:

Telling the Complete Carbon Story: We continued advancing our understanding of the full climate impact of our forests and products, and in 2025 added a new dimension: the potential avoided emissions when our wood products are used in place of more carbon-intensive materials like steel and concrete. We also generated $13.3 million in carbon credit sales from our regulatory compliance operations in carbon markets, demonstrating how climate action can align with financial performance.
Delivering on Our Climate Targets and Decarbonizing Operations: We continued delivering against our Science Based Target initiative (SBTi)-validated emissions reduction targets, achieving a 25% reduction in absolute Scope 1 and 2 emissions (from our 2019 baseline) and a 20% reduction in Scope 3 emissions (from our 2020 baseline) by the end of 2025, keeping us on track toward our 2030 goals. Additionally, 78% of our global energy use came from biogenic and renewable sources.
Highlighting Biodiversity: We published our first Taskforce on Nature-related Financial Disclosures (TNFD) report focusing on our Alberta operations, working in partnership with the National Council for Air and Stream Improvements (NCASI) and with funding from the Forest Resource Improvement Association of Alberta (FRIAA). In 2025, West Fraser released its Biodiversity Policy and the Biodiversity Community of Excellence began providing governance and strategic direction across its five pillars of biodiversity stewardship.
Partnering with Indigenous Nations: A key milestone in 2025 was the finalization of a long-term fibre supply agreement with Lake Babine Nation Forestry for our Smithers, B.C. lumber mill, establishing a new model for collaborative forest stewardship in the province.
Supporting Our People and Earning Recognition as a Top Employer: West Fraser was named one of Canada's Top 100 Employers for the thirteenth consecutive year and earned Mental Health America's Bell Seal for Workplace Mental Health certification, recognizing our commitment to employee wellbeing.
