                      Our chemical management program works hand in hand with our product stewardship program, where we integrate environmental, health and safety considerations into our products, from product design to end of life.

                      REDUCING RISK

                      We focus company-wide on reducing chemical risk through:

                      • Use of a comprehensive local chemical-approval process where potential new chemicals are thoroughly reviewed and any needed controls are determined prior to local approval and use.
                      • Reducing or eliminating the overall number of chemicals used in our operations, including certain chemicals and products containing PCBs, asbestos, lead-based paints and certain aerosols.
                      • Seeking less-hazardous substitutes for chemicals and implementing their use across our company.
                      • Continuing our chemical-reduction efforts through inventory management of all chemical products and Safety Data Sheet management.
                      • Use of a company-wide database for all safety data sheets and labels for hazardous chemicals, accessible to all employees.  

                      TRANSPARENT REPORTING

                      Annually, we publicly report the release of certain chemicals into the air, water and land under the U.S. Toxic Release Inventory (search for "Facility Name" containing "Weyerhaeuser") and the Canadian National Pollutant Release Inventory (search for "Weyerhaeuser" in "Facility Name"). With rare exceptions, these are lawfully-permitted releases that are made in a controlled fashion after steps have been taken to reduce the emissions and mitigate their effects. Both inventories mandate that we report total emissions without regard to changes in production levels. 

                      We also provide detailed information for our Kenora Timberstrand facility under Ontario's Toxic Substance Accounting program:

                      • Kenora Timberstrand Toxic Substance Accounting for 2017 and 2018.
