Climate Action

Plan Bay Area grew out of the California Sustainable Communities and Climate Protection Act of 2008 (California Senate Bill 375, Steinberg), which requires each of the state’s 18 metropolitan areas – including the Bay Area – to reduce greenhouse gas emissions from cars and light trucks. The first Plan Bay Area was adopted in 2013. The update, Plan Bay Area 2040, was adopted in 2017.

Public comments were key in the development of Plan Bay Area 2040, and those comments helped inform the final decisions that shaped the plan.
