2 Studies Target Sticking Points, Gaps in Life-Cycle Calculations of Biofuels

Conducting in-depth life-cycle assessments of the environmental impacts of biofuels is complicated, and new research suggests some questions in comparing biofuels to alternatives like petroleum-based fuels will never be answered. Furthermore, one study argues, consumer choices driven by price differences between bio-based and petroleum-based fuels will play into how biofuels affect the environment, adding another layer of complication that must considered. The two papers were recently published by the Energy Biosciences Institute, a partnership among oil giant BP PLC; the University of California, Berkeley; the University of Illinois, Urbana-Champaign; and the Lawrence Berkeley National Laboratory.
