Buy Clean California State Law

The Buy Clean California Act (BCCA) (Public Contract Code Sections 3500-3505), states the 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. The BCCA targets carbon emissions associated with the production of structural steel, concrete reinforcing steel, flat glass, and insulation. When used in public works projects, these eligible materials must have a GWP that does not exceed the limit set by DGS.
