New California Rules Affecting Emissions From Metals Industry Goes Into Effect This Week

Under California’s Buy Clean California Act (BCCA), the state Department of General Services (DGS), in consultation with the California Air Resources Board (CARB), is required to establish and publish the maximum acceptable Global Warming Potential (GWP) limit for four eligible materials.

Specifically, the BCCA targets carbon emissions associated with the production of structural steel (hot-rolled sections, hollow structural sections, and plate), concrete reinforcing steel, flat glass, and mineral wool board insulation. When used in public works projects, these eligible materials must have a GWP that does not exceed the limit set by DGS. The state established maximum acceptable GWP limits on January 1, 2022.

Beginning July 1, 2022, awarding authorities will determine GWP limit compliance of eligible materials using Environmental Products Declarations (EPDs).
