County of San Diego
Climate Action Plan

The County of San Diego is committed to helping communities thrive while protecting the region’s unique and diverse natural resources. One of the County’s sustainability tools is the Climate Action Plan (CAP), which contains a series of measures to reduce greenhouse gas emissions over the next 30 years. These measures are administered through multiple County departments and focus on activities that occur within the unincorporated area of the region, and within County-owned facilities, regardless of location.

The County is actively engaged in implementing the CAP and its 26 measures to reduce greenhouse gas emissions.

In response to a June 12, 2020 Court of Appeal ruling, the County will be revising its 2018 CAP and Environmental Impact Report (EIR) but will continue implementing sustainability measures to effectively reduce greenhouse gases (GHGs) as part of its ongoing commitment to the environment. The court ruling struck down part of the CAP’s EIR but did not find fault with its 26 GHG reduction measures. To address the court ruling, the CAP and EIR will be revised in partnership with residents, and business and environmental groups.


The County reduced 130,075 metric tons of carbon dioxide equivalent by implementing Climate Action Plan measures in 2019. Find status updates on all 26 measures on the CAP dashboard, and read the full 2019 Annual Monitoring Report to learn more. 


The CAP reduces greenhouse gas emissions through 26 enforceable, quantifiable, and achievable measures within five emissions sectors. Roll over and click on each button to learn more.
