The 2018 Climate Action Plan (CAP), adopted on February 14, 2018, outlines 11 strategies and 26 measures to meet the State’s 2020 and 2030 greenhouse gas (GHG) emissions targets while progressing toward the 2050 GHG reduction goal.

On September 30, 2020, the County Board voted to set aside its approval of the County’s 2018 CAP and related actions because the Final Supplemental Environmental Impact Report (2018 CAP SEIR) was found to be out of compliance with the California Environmental Quality Act (CEQA). The court ruling did not find fault with the 2018 CAP’s 26 GHG reduction measures, and the County continued implementing the sustainability measures to reduce emissions while addressing the legal deficiencies in the plan.

The 2024 CAP, adopted on September 11, 2024, replaces the 2018 CAP as the County's comprehensive framework for reducing GHG emissions. This updated plan resolves the issues identified in the 2018 CAP’s SEIR. Developed in partnership with residents, businesses, and environmental groups, the 2024 CAP reaffirms the County’s commitment to sustainability while refining its approach to achieving long-term environmental goals. The County will continue to monitor and report on the implementation progress of the 2018 CAP measures through the end of 2024.
