CAlifornia Air Resources Board
The California Air Resources Board (CARB) is charged with protecting the public from the harmful effects of air pollution and developing programs and actions to fight climate change. From requirements for clean cars and fuels to adopting innovative solutions to reduce greenhouse gas emissions, California has pioneered a range of effective approaches that have set the standard for effective air and climate programs for the nation, and the world.
CARB's mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. CARB is the lead agency for climate change programs and oversees all air pollution control efforts in California to attain and maintain health-based air quality standards.
CARB is one of several stewards of California Climate Investments and support programs funded by this initiative. Learn more about California Climate Investments below.
California Climate Investments
Proceeds from the Cap-and-Trade Program facilitate comprehensive and coordinated investments throughout California that further the State’s climate goals. These investments support programs and projects that reduce greenhouse gas (GHG) emissions in the State and also deliver major economic, environmental, and public health benefits for Californians, including meaningful benefits to the most disadvantaged communities.
- Transportation & Sustainable Communities
California’s transportation sector represents 41 percent of GHG emissions statewide. SB 862, enacted by the Legislature and Governor Brown in 2014, and SB 200, enacted by the Legislature and Governor Newsom in 2019, established continuous appropriations of 65 percent of the available GGRF proceeds for certain transportation and sustainable communities programs, including High-Speed Rail, local and regional public transit, safe and affordable drinking water, and affordable housing projects. In addition, annual appropriations are supporting the Low Carbon Transportation Program.
- Clean Energy & Energy Efficiency
California’s energy sector—including use of electricity and natural gas—accounts for about a quarter of the State’s near-term GHG emissions. In 2015, Governor Brown signed SB 350, which requires the State to double building energy efficiency and increase renewable energy to 50 percent by 2030. As further directed by SB 100, which was signed by Governor Brown in 2018, California’s long-term goal is to achieve carbon neutrality by 2045.
- Natural Resources & Waste Diversion
California’s natural and working lands comprise three-quarters of the land base statewide. These lands provide food, fiber, and a variety of ecosystem services including important opportunities for climate mitigation that reduce GHG emissions from wildfire and land conversion, and store carbon in biomass and soils. In 2020, Governor Newsom signed an executive order with a state goal to conserve 30% of California’s lands and coastal waters by 2030.
State agencies receiving appropriations, referred to as “administering agencies,” develop and implement a suite of programs within or across three priority areas:
