With enactment of the California Global Warming Solutions Act of 2006, (AB 32; Stats. 2006, chapter 488) the Air Resources Board (ARB) was tasked with several new responsibilities to help address the threat of global warming.

Two of these new responsibilities, greenhouse gas emissions inventory and mandatory reporting are complementary efforts to assess and monitor California's progress toward GHG emissions quantification and mitigation. The first effort established the California 1990 Greenhouse Gas Emissions Level and 2020 Emissions Limit and the second lead to the adoption by the ARB of a regulation to require the mandatory reporting and verification of greenhouse gas emissions.
