California’s Pathway to a
low carbon Future

Cutting greenhouse gas emissions, growing the economy, improving public health



California is actively reducing its contribution to global climate change—and we have undertaken some of the world’s most ambitious and comprehensive programs to address the challenge.

We believe climate action and economic prosperity go hand in hand, and that addressing climate change means more opportunities for California’s economy, including our thriving low-carbon and clean-tech industries.  

Recognizing that sources of greenhouse gas emissions and air pollution are the same, the state has taken a cross-cutting approach to reduce the impacts of both these challenges to minimize cost, streamline regulatory processes and maximize economic, public health, and environmental benefits. 

Building a Foundation

AB 32: the Global Warming Solutions Act was signed into law in 2006 requiring California to reduce greenhouse gas (GHG) emissions to 1990 levels by 2020 representing a 15% reduction.

California is on track to meet the target while gross domestic product (GDP) continues to rise, a clear demonstration that the state can grow its economy while aggressively fighting climate change.


Aggressive Goals for the Future

Building on California’s success to date, in 2015 Governor Edmund G. Brown Jr. established a greenhouse gas reduction target of 40% below 1990 levels by 2030. The state’s strategy focuses on 6 pillars – keys to cutting emissions across the California economy in order to meet the target and help California be more resilient in the face of effects of climate change, many of which are already impacting the state’s natural systems and economy.

California's Climate Timeline


Progress to date

Data shows that California’s programs are working as designed.

  • Carbon intensity of the state’s economy has dropped 23% from the peak in 2001, and declined an average of 1.9% per year over the past four years as GDP grew 6.6% overall during the same period.

  • California has cut ambient black carbon emissions (soot) more than 90% since 1960.

  • California companies attract billions in clean tech investments, driving an industry with job growth triple that of the overall economy.

  • Energy efficiency rules have saved consumers $74 billion since 1977 and provide Californians with some of the lowest monthly utility bills in the United States.
