Embodied Carbon
In September 2022, Governor Newsom signed Assembly Bill 2446 (Holden), which requires CARB to develop a framework for measuring and reducing the embodied carbon of building construction materials, primarily at the materials production stage, with a target of a 40 percent net reduction in GHG emissions no later than the end of 2035, and an interim target of a 20 percent net reduction by the end of 2030.
