SBTi VALIDATES WEST FRASER'S SCIENCE-BASED EMISSIONS REDUCTION TARGETS

World's largest renewable building materials producer to materially reduce GHG emissions by 2030

VANCOUVER, BC, April 13, 2023 /CNW/ - West Fraser Timber Co. Ltd. ("West Fraser" or the "Company") (TSX and NYSE: WFG) announced today that the Science Based Targets initiative (SBTi) has validated its scope 1, 2 and 3 emissions reduction targets. This validation further supports West Fraser's plan to achieve near-term greenhouse gas ("GHG") reductions across all its operations located in the United States, Canada, United Kingdom and Europe.

SBTi helps companies to set and validate emission reduction targets in line with climate science and Paris Agreement goals. It promotes best practice in science-based target setting and independently assesses companies' targets. To accelerate corporate climate action, SBTi is focused on significant reductions in global emissions before 2030 and achieving net-zero emissions before 2050.

"Climate action is a fundamental element of West Fraser's sustainability strategy," said Ray Ferris, President and CEO of West Fraser. "Validation of West Fraser's proposed targets, committing to reduce GHG emissions in line with climate science and aligned with the Paris Agreement goals by 2030, furthers the credibility of our targets and builds on our solid legacy of sustainability performance of our products while enhancing the social, environmental and economic benefit in the communities in which we operate."

West Fraser is on a path to reduce its scope 1 and 2 GHG emissions 46.2% by 2030 and its scope 3 GHG emissions 25% by 2030.
