Policy Developments

California has long been a leader in innovative energy and climate policies—from the creation of the Los Angeles Air Pollution Control District in 1947 to the passage of the state’s landmark Global Warming Solutions Act (AB 32) in 2006 and the 2018 commitment to transition to 100 percent clean energy sources by 2045 (SB100). The state has led the way as an early adopter of a clean energy future, implementing policies to reduce pollution, improve energy efficiency, and incentivize clean energy and clean technology innovation that have been replicated in both other states and nations. To meet its climate goals moving forward, California will need to build upon this foundation with policies that tackle harder-to-reach emissions reductions, including those from the transportation sector and buildings.

While the events of the last two years—including the COVID-19 pandemic and extreme heat waves that threaten the reliability of the grid—have taken center stage in terms of policy priorities here in California, there have also been positive developments. The federal government passed the Inflation Reduction Act in August 2022, directing a historic investment of $369 billion toward electrifying transportation and buildings while expanding renewable energy generation over the next 10 years. Recent international climate negotiations at the UN conference in Sharm el-Sheikh, Egypt demonstrated global concern for the climate, and included new international commitments, including new restrictions on emissions of methane. In California, there is still room for policy innovation in the clean energy and climate spaces, but some recent developments hold promise, such as increased offshore wind generation, clean vehicle infrastructure expansion and investment, and climate resiliency.

As California and the nation look ahead to prospects of policies that help strengthen our economy while protecting our environment, it is worth highlighting how far the state and nation has come. The policies in the subsequent timeline reflect decades of collaboration and innovation to address climate and pollution concerns while simultaneously developing one of the world’s largest economies.
