Assembly Bill 32, or the Global Warming Solutions Act of 2006 is an environmental law passed by the California State Legislature and signed into law by Gov. Arnold Schwarzenegger on September 27, 2006.[1]

AB 32 says that by the year 2020, the level of emissions of greenhouse gases in the state must be reduced to the level that such emissions had in 1990. It is estimated that reducing the state's greenhouse gas emissions to 1990 levels would require an approximate 25% reduction over the level of emissions in 2006, the year the bill was signed.

The California Environmental Protection Agency is charged with implementing the provisions of AB 32.

The California Senate Environmental Quality Committee approved AB on June 26, 2006.[2] AB 32 was written by Fabian Nunez (D-Los Angeles) and Fran Pavley (D-Agoura Hills).

Greenhouse gases

AB 32 defines "greenhouse gases" as:

  • Carbon dioxide (CO2)
  • Methane (CH4)
  • Nitrous oxide (N2O)
  • Hydrofluorocarbons (HFCs)
  • Perfluorocarbons (PFCs)
  • Sulfur hexafluoride (SF6).


Cost of electricity

According to the San Francisco Chronicle, electricity rates are likely to rise by about 15% in the first few years of the implementation of AB 32, because the generation of electricity using renewable resources costs more than the generation of electricity from non-renewable resources.[3]

In 2010, the Proposition 23, the "California Jobs Initiative" was proposed, but failed at the ballot box. It would have frozen the provisions of AB 32 from going into effect until the unemployment rate in California dropped to 5.5% or less for four quarters in a row. When AB 32 was enacted in 2006, the state's unemployment rate was 4.8%. In the early part of 2010, the unemployment rate crept over 12%.[4]



  • In 2008, the California Air Resources Board (ARB) adopted a plan to implement the provisions of AB 32.[5]
  • A variety of environmental groups filed a lawsuit against ARB, arguing that its 2008 plan was adopted before the agency completed a required environmental review, and that it did not adequately consider alternatives to cap and trade as its primary method of implementing AB 32.[5]
  • On February 4, San Francisco Superior Court judge Ernest Goldsmith agreed with the plaintiffs and ordered the ARB not to go forward with its 2008 plan to implement AB 32 until it has come into compliance with the California Environmental Quality Act. Goldsmith's ruling said that ARB "seeks to create a fait accompli by premature establishment of a cap-and-trade program before alternatives can be exposed to public comment and properly evaluated by the ARB itself," that the analysis it did provide includes "no evidence to support its chosen approach" and that ARB's decision to approve the larger plan without a complete review "undermines (the state environmental quality act's) goal of informed decision-making."[5]

Low carbon rules

On December 30, 2011, federal judge Lawrence J. O'Neill of the U.S. District Court for the Eastern District of California issued a preliminary injunction against a provision in AB 32 about fuel imports into the state infringes on Congress's constitutional authority over interstate commerce.[6]

The injunction says that AB 32 unconstitutionally discriminates against crude oil and ethanol imported into the state.[6]

Charles Drevna, president of the National Petrochemical and Refiners Association, applauded the court ruling and said that if that provision of AB 32 was upheld, ."..the standards would have hurt consumers by discriminating against their use of renewable fuels from the Midwest and crude oil from our neighbor and ally Canada. Different states could have followed California's example and created a patchwork quilt of varying fuel standards that would have raised the costs of manufacturing gasoline and diesel fuel across the United States."[6]

Trip Van Noppen, president of Earthjustice, an environmental law firm, responded to the injunction by saying, "It is not surprising that the oil industry is attacking these programs, but like previous attacks in the courts and at the ballot box, we expect this one ultimately to fail."[6]

Carbon offset auctions

Beginning in the fall of 2012, under the terms of AB 32, the state will be able to conduct auctions of "pollution credits" to businesses in the state that product carbon, such as oil refineries and power plants. These companies can bid in an auction to pay money to the state in exchange for the ability to continue to produce atmospheric pollutants at a higher-than-would-otherwise-be-allowed level.

The California Legislative Analyst's Office estimates that these auctions will yield anywhere from $1 billion to $3 billion a year for the state, possibly rising as high as $14 billion a year in 2015. This is significant, considering that in 2012, the state's budget deficit is approximately $9 billion.

Several businesses have filed lawsuits against this part of the AB 32 legislation. In addition, it is likely that the state would only be able to spend any money it does raise in these auctions -- if they are allowed to proceed -- on programs that are narrowly targeted to reduce greenhouse gas emissions.[7]
