Life-cycle greenhouse gas emissions of transportation fuels: issues and implications for unconventional fuel sources

July 2011

The effectiveness and efficiency of regulatory and other policy approaches intended to reduce the greenhouse gas emissions from transportation fuels can hinge on the fuel life-cycle analysis (LCA). This report provides a summary of the workshop of the same name, convened in September 2010 by the Climate Change Working Group. It focuses on the LCA for transport fuels from unconventional hydrocarbon sources and associated regulatory issues and implications. Also, it examines these in the context of experience gained in the study of conventional hydrocarbon sources, biofuels, electric vehicles, and other alternatives.
