The California Global Warming Solutions Act, or AB 32, was signed into law in 2006. As the nation’s most comprehensive, economy-wide global warming pollution reduction program, AB 32 requires the state’s global warming pollution to be reduced to 1990 levels by 2020 through a suite of programs and policies, including a declining statewide cap on global warming emissions.
As part of that effort, in 2011 California enacted a 33% renewable electricity standard, which requires that all utilities in the state obtain at least 33 percent of their electricity from clean, renewable sources, such as wind or solar power, by 2020. In addition, in 2012 California adopted global warming standards for cars and light trucks, as well as requirements for zero-emission vehicles, which will reduce global warming emissions from the transportation sector.
