EPA Sets Dates for Workshop on Biofuel Greenhouse Gas Modeling

EPA has announced a two-day virtual public meeting/workshop on biofuel greenhouse gas (GHG) modeling to “solicit information on the current scientific understanding of greenhouse gas modeling of land-based biofuels in the transportation sector (link). The sessions are set for Feb. 28 and March 1, with EPA aiming to gather information that “will be used to inform a range of current and future actions, including EPA’s methodology for quantifying the greenhouse gas emissions under the Renewable Fuels Standard.” EPA’s Office of Transportation and Air Quality is holding the sessions in consultation with USDA and the Department of Energy. EPA said they want to use the sessions to start a public process for input on “how to incorporate the best available science into an update of our lifecycle analysis (LCA) of biofuels,” and to assess what “steps EPA should take next in this work area.” This figures to be a potentially important session as biofuel supporters have maintained that the current GHG modeling and LCA being used for corn-based ethanol is outdated.
