Embodied Carbon
Assembly Bill(s) 2446 and 43 (Holden), signed by Governor Newsom, require the California Air Resources Board to develop a framework for measuring and then reducing the average carbon intensity of the materials used in the construction of new buildings, including those for residential uses. This includes developing a comprehensive strategy for the state’s building sector to achieve a 40% net GHG reduction, no later than 2035.
