Washington HB2273 aims to reduce embodied carbon emissions in buildings and building materials.

Washington HB2273 establishes standards to reduce embodied carbon emissions in buildings and building materials. The bill requires a 30 percent reduction in annual embodied carbon emissions by 2030. Building projects can comply by maintaining at least 45 percent of an existing structure and envelope, demonstrating a reduction in life-cycle stage emissions, or using a whole building life-cycle assessment. The state building code council will adopt rules to define covered products, determine calculation methods, and establish industry averages.
