Help Update the County’s Climate Action Plan
Contra Costa County is updating its Climate Action Plan, which outlines the actions the County will take to address our changing climate. In the meantime, we'll be focusing our work in a few key areas. Learn more by reading our Interim Climate Action Work Plan for 2023-2024 (PDF).
Learn more about our current Climate Action Plan (PDF) adopted in 2015, and the Interim Climate Action Work Plan for 2021-2022 (PDF).
We held several meetings in September and October, 2019 to learn about community goals and strategies to reduce pollution emissions in our County and be more resilient. Visit the Envision Contra Costa 2040 webpage to find presentations, information for the Climate Action Plan update, and to submit your ideas.
