ABSTRACT
As no binding global commitment has yet been developed to respond to the threat of climate change once the Kyoto Protocol expires, state governments have begun to develop regional, transnational, and subnational climate change mitigation strategies. 1 One such subnational strategy is California’s Global Warming Solutions Act (AB 32), passed in 2006. This was the first enforceable statewide legislation in the United States to cap and reduce GHG emissions from major industries. It requires California to reduce its level of GHG emissions to 1990 levels by 2020, and 80 percent reduction from 1990 levels by 2050. California has since implemented a number of regulations and a cap-and-trade system to achieve this goal.
