Today, Assemblyman Chris Holden’s bill, Assembly Bill 2446: The Carbon Intensity of Construction and Building Materials Act, passed the Assembly and heads for the governor’s office. This measure is the first in the country and would require the state to develop a framework to measure and then reduce greenhouse gas emissions in the construction of all public and private buildings.

“With AB 2446, we hope to bring conscious design to reduce materials used and the use of low-carbon building materials to help both people and the planet,” said Chris Holden, member of the Assembly. “The decisions we make today impact generations to come.”

The bill would require the California Air Resources Board to include a comprehensive strategy to achieve a 20% net reduction in GHG emissions from building materials by December 31, 2030 and a 40% net reduction no later than December 31, 2030. December 2035. This bill will require a lifecycle assessment to determine the carbon intensity of residential and nonresidential buildings in the state. AB 2446 would also require the Board to leverage state and federal incentives to reduce the cost of implementing the framework and to increase economic value to the state.

“Creating a framework to measure and then reduce the average carbon intensity of materials used in the construction of new buildings, including those for residential use, is critical to California’s future,” Holden said.
