As the House Energy and Commerce Committee moves forward on developing climate change legislation, it appears that the legislation will include a low carbon fuel standard (LCFS). An LCFS would require reductions in the life-cycle greenhouse gas emissions of fuels used in vehicles. According to an article in Carbon Control News, sources indicate that an LCFS may be a more effective way to address vehicle emissions than a stand-alone cap-and-trade program. How the LCFS will be handled in the legislation isn’t clear, and one issue to keep an eye on is how any new LCFS requirement will impact EPA's current, on-going, obligation under the renewable fuel standard provisions of the Clean Air Act to develop LCFS methodologies (recent amendments to the Clean Air Act require increased use of low-carbon fuels—measured on a life-cycle basis—and EPA is late in releasing its proposed methodologies for determining the life-cycle emissions of fuels). More should be known by the end of the month, when the draft legislation is expected to be released.
