This bill would require CARB, by December 31, 2030, to evaluate and report its findings and recommendations to the Legislature on the feasibility and tradeoffs of achieving the policy goal of ensuring that by 2045 statewide anthropogenic greenhouse gas emissions are reduced to at least 85% below the statewide greenhouse gas emissions limit, relative to alternative scenarios that achieve the policy goal of achieving net zero greenhouse gas emissions as soon as possible, but no later than 2045, and achieving and maintaining net negative greenhouse gas emissions thereafter.
