This Type III environmental declaration is developed according to ISO 21930 and 14025 for average cedar siding products manufactured by the members of the Western Red Cedar Lumber Association. This environmental product declaration
(EPD) reports environmental impacts based on established life cycle impact assessment (LCA) methods. The reported
environmental impacts are estimates, and their level of accuracy may differ for a particular product line and reported
impact. LCAs do not generally address site-specific environmental issues related to resource extraction or toxic effects
of products on human health. Unreported environmental impacts include (but are not limited to) factors attributable
to human health, land use change and habitat destruction. Forest certification systems and government regulations
address some of these issues. The products in this EPD conform to: timber harvesting and silvicultural practices regulation
of British Columbia (BC) and forest certification schemes (Canadian Standards Association, Forest Stewardship Council
(FSC), and Sustainable Forestry initiative (SFI)). EPDs do not report product environmental performance against any
benchmark.
