California state legislation

MIT Alumni for Climate Solutions
California is one of the leading states in the US to set goals to limit carbon emissions. In 2018, California established the goal of 100 % clean electricity and overall carbon neutral policy for the state by 2045. Below is a short summary of its legislative and executive actions since 2006, with links to documents.

California's Global 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 entire economy.

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.
