A National Academy of Sciences (NAS) panel is publicly launching a study to refine lifecycle greenhouse gas analysis (LCA) practices, a crucial issue for determining which biofuels or other low-carbon fuels should be encouraged or required under various federal and state low-carbon fuels programs. Among the topics NAS will review are continuing uncertainties in LCA analysis, factoring “co-products” of low-carbon fuels into such accounting, and possibilities for facilitating cooperation across multiple fuels programs. Also, Renewable Fuels Association Chief Economist Scott Richman told the panel that the group favors an LCA approach that is “technology- and feedstock-neutral,” with “consistent analytical boundaries across all fuels and vehicles in terms of direct effects and any indirect effects.”
