Community Climate Action Plan

The Community Climate Action Plan (CCAP) is a strategic roadmap to guide unincorporated San Mateo County in preparing for climate risks and creating impactful greenhouse gas emission reductions. The Community Climate Action Plan (CCAP) outlines priority actions to achieve a 45% reduction of greenhouse gas emissions over 1990 levels by 2030 and carbon neutrality within unincorporated San Mateo County by 2040. The plan was finalized in October 2022 when it was adopted by the Board of Supervisors.

By reaching goals outlined in the plan, the County of San Mateo will demonstrate leadership in climate action and support the rate of action needed to mitigate the harmful impacts of climate change that the county is already experiencing. The challenge ahead is not just about the fuel that powers our homes and cars, it is about the quality of our communities and our built and natural environments.

San Mateo County Emissions Forecast

The goals in the CCAP are to achieve a 45% reduction below 1990 levels by 2030 and carbon neutrality by 2040. Carbon neutrality is defined by the point at which the removal of carbon pollution from the atmosphere meets or exceeds emissions (i.e. San Mateo County is removing more carbon from the air than we are emitting.)

California has a statewide goal of greenhouse gas emissions to be reduced to 40% below the 1990 emissions level by 2030.
