Buy Clean California Act: eligible materials: product-specific global warming potential emissions.

Existing law, the Buy Clean California Act, requires the Department of General Services, by January 1, 2022, to establish and publish in the State Contracting Manual, in a department management memorandum, or on the department's internet website, a maximum acceptable global warming potential for each category of eligible materials, set at the industry average of facility-specific global warming potential emissions for that material, expressed as specified. Existing law defines "eligible materials" for those purposes to mean carbon steel rebar, flat glass, mineral wool board insulation, or structural steel. This bill would revise the definition of "eligible materials" to delete mineral wool board insulation and additionally include gypsum board, insulation, carpet and carpet tiles, and ceiling tiles. The bill would also require the department, by January 1, 2024, to establish and publish a maximum acceptable global warming potential for each category of eligible materials, set at the industry average of product-specific global warming potential emissions for those materials, expressed as specified. Existing law requires the department, by January 1, 2025, and every 3 years thereafter, to review the maximum acceptable global warming potential for each category of eligible materials and authorizes the department to adjust that number downward for any eligible material to reflect industry improvements under specified circumstances. This bill, instead, would require the department, by January 1, 2027, and every 3 years thereafter, to review the maximum acceptable global warming potential for each category of eligible materials, expressed as specified, and would authorize the department to adjust that number downward for any eligible material to reflect industry improvements under specified circumstances. This bill would authorize the department to establish and publish a maximum acceptable global warming potential for any major structural, high-impact architectural, civil, or high-impact materials for which there is either a product category rule or an environmental product declaration.
