The California Air Resources Board proposed revisions to the California Global Warming Solutions Act of 2006 (AB 32; Statutes of 2006, chapter 488). The changes are proposed to comply with a 2009 executive order that the Air Resources Board adopt a regulation by July 31, 2010, requiring load serving entities to meet a 33% renewable energy target by 2020. http://www.arb.ca.gov/energy/res/meetings/052010/may14draftregulation.pdf.
