Warming Solutions Act, AB 32, passed in 2006, set a statewide limit on greenhouse
gas emissions and committed to transition to a sustainable, clean energy
economy. Greenhouse gases were targeted to reach 1990 levels by 2020.
In 2015, California passed SB 350, the Clean Energy & Pollution Reduction Act, which required the state to increase its renewable energy mix to 50 % and double the energy efficiency of existing buildings by 2030, and targeted greenhouse gases to reach 80 % below 1990 levels by 2050..
In 2016, SB 32 extended and strengthened the limit on greenhouse gas emissions in California, raising its goal for greenhouse gas emissions to 40 % below 1990 levels by 2030 and extending cap-and-trade until 2030.
SB32 also established policies, incentives, and market rules toward a low-carbon, clean energy economy by promotion of renewables and modernizing and automating energy options in the state.
In 2018, a number of additional bills and rules were approved:
SB 100 commits the state to get 60% of its electricity from clean sources by 2030, and 100% by 2045.
SB 700 extends incentives for wind, biogas, and fuel cells.
AB 2145 and AB 2127 expands electric vehicle charging infrastructure.
AB 2061 encourages fleet-wide adoption of commercial electric vehicles.
SB 237 and SB 1131 provides access to energy-efficiency programs for agriculture and industry and allows purchase directly from independent sources rather than utilities.
SB 1339 facilitates connection to microgrids.
AB 1796 encourages installation of electric-vehicle-charging access on rent-controlled properties.
SB 957 gives low-income drivers with low-emission vehicles
preferential access to carpool lanes.
The Governor's executive order, B-55-18, sets the goal of achieving carbon neutrality by 2045, zeroing greenhouse gases across the
California's Energy Commission approved a new rule mandating all new homes constructed in the state be equipped with solar panels by Jan. 1, 2020.
