Assembly Bill 2446 and AB 43 direct the California Air Resources Board (CARB) to develop a reporting framework to measure and then reduce embodied carbon in building materials.
Surveys
CARB is seeking feedback from the public and industry partners throughout the development of this reporting mechanism. One form of this feedback is through voluntary data sharing, where industry can choose to share embodied carbon-related data with CARB to increase understanding of the current availability of embodied carbon data in the field.
The responses that CARB receives through this survey will be treated as Confidential Business Information pursuant to Code of California Regulations, title 17, sections 91000-91022 and will not be shared with external stakeholders.
