Air Board Approves Early Action List for Greenhouse Gas Controls

By Published On: June 25, 2007

On a 6-3 vote, the California Air Resources Board June 21 approved a list of “early action” greenhouse gas reduction measures, including development of alternative low-carbon fuels aimed at mitigating climate change. The low carbon standard would require fuel providers—including producers, importers, refiners, and blenders—to ensure that the mix of fuels they sell in California produces less greenhouse gas emissions when burned in vehicles. The goal is to cut greenhouse gas emissions from vehicles by at least 10 percent by 2020. The second measure would restrict the use of refrigerants with high global-warming potential like hydrofluorocarbons in do-it-yourself recharging of leaky automotive air conditioning systems. Regulators also are considering requiring low-global warming potential refrigerants in new vehicle air conditioning systems and adding an air conditioning leak test to the state’s vehicle smog check program. The third measure CARB approved was to set standards for the installation and performance of gas collection and control systems at municipal landfills, where organic matter decomposes and produces methane. An estimated 94 percent of municipal landfills in California have active gas collection systems, but the Air Board also wants controls at 41 landfills that do not yet have those systems. The state’s climate change law, AB 32, mandated the Air Board to develop and approve the list of early action measures by June 30. It consists of greenhouse gas emission reduction measures the Air Board pledges it can adopt as enforceable rules before Jan. 1, 2010.
