California’s Global Warming Solutions Act of 2006 established the state’s trajectory toward ambitious emissions-reduction targets and the state has continually built on this law. California considered the country’s leader in climate action for decades, aimed to reach 1990 levels for greenhouse gas emissions by 2020; and is now targeting 40 percent below 1990 levels by 2030 and carbon neutrality by 2045. It established a “Renewables Portfolio Standard” in 2002 and subsequently accelerated this over the years as part of one of the most ambitious clean energy programmes in the country. California will require its electricity sector to reach clean energy targets of 60 percent of sales by 2030 and 100 percent by 2045. In the transportation sector, California aims for 5 million zero-emissions vehicles and 250,000 charging stations by 2030, and the phase-out of sales of vehicles with internal combustion engines by 2035. California’s former Governor Jerry Brown was a co-founder of the US Climate Alliance. The state is a member of 17 regional and national climate agreements and has signed 64 bilateral agreements with other countries.
