Climate change is a real, urgent, and significant threat, with impacts being felt today in Los Angeles County, across the U.S., and around the world. Climate change has already adversely impacted L.A. County residents—especially the most vulnerable—and can harm the health, safety, and welfare of future generations. On September 4, 2018, the County Board of Supervisors adopted a motion supporting the 2016 Paris Climate Agreement and added the County to the We Are Still In Declaration. By this action, the County is committed to adapting its programs and services to reduce unincorporated Los Angeles County's greenhouse gas (GHG) emissions and help limit global temperature increases.

This 2045 Los Angeles County Climate Action Plan (2045 CAP) is the County’s strategy to meet the goals of the Paris Agreement and achieve carbon neutrality for the unincorporated areas of Los Angeles County. The 2045 CAP builds on previous climate action work from the Unincorporated Los Angeles County Community Climate Action Plan 2020 (2020 CCAP), adopted in October 2015 as a subcomponent of the Air Quality Element of the Los Angeles County General Plan 2035. The 2045 CAP identifies strategies, measures, and actions to mitigate GHG emissions from community activities, which may include some municipal operations.

The public can provide input by reviewing and commenting on the Revised Draft 2045 CAP and Recirculated Draft Environmental Impact Report (DEIR). The public review period began on March 16, 2023 and will end on May 15, 2023. Comments should be sent to: [email protected].
