Our Climate Action Progress

In 2023, we reached 29.7% below 2005 levels of emissions. Now let's beat our 2025 Target!

Updated GHG Emissions Scale


Our Climate Action Plan

The Final 2020 Climate Action Plan (CAP) was adopted by the City Council at the October 27, 2020, meeting.

The climate action plan is designed to be a blueprint for our community's response to the challenges posed by climate change. Though climate change is a global problem, local action can contribute to reducing greenhouse gas (GHG) emissions. To learn more, read our Climate Action Plan or view the Executive summary. 


    Initial Climate Action Plan Study

    The Final 2020 CAP Initial Study-Negative Declaration addresses the potential physical environmental effects of the implementation of the 2020 CAP in accordance with the California Environmental Quality Act (CEQA).

    What is Climate Change?

    Climate change is the long-term shift in the Earth's average temperatures and weather conditions. It is primarily driven by human activities, especially the burning of fossil fuels like coal, oil, and gas, which release greenhouse gases (GHGs) into the atmosphere. These gases, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), trap heat from the sun, creating a "greenhouse effect" that leads to global warming. In 2023, the world experienced its warmest year on record. Here in Millbrae, we have felt the effects firsthand, with extreme weather events and rising sea levels impacting our community.
