The enactment of AB32 committed California to reduce GHG emissions to 1990 levels by 2020. The legislation empowered the California Air Resources Board to adopt regulations that would achieve “the maximum technologically feasible and cost-effective GHG emission reductions”. With this legislation, California was the first state to set legally-binding caps on GHG emissions.
California achieved the targets set by AB32 in 2016, four years ahead of the deadline.
