EPA sets new targets for renewable fuel

  • 01-Jun-2009 03:33 EDT

Limits on life-cycle emissions of greenhouse gases (GHG) in the production and use of certain types of renewable fuel are proposed as a new requirement in the EPA's updating of the U.S. Renewable Fuel Standard (RFS1). A workshop on that aspect of the proposed updating, including a look at land-use impacts on GHG, will be held June 10 and 11 in Washington, D.C. The agency will hold a public hearing June 9 in Washington on the overall RFS2 program, which mandates a larger volume of renewable fuel than does RFS1. RFS2 also updates RFS1 by introducing three sometimes overlapping categories of renewable fuel (cellulosic biofuel, biomass-based diesel, and advanced biofuel), each with mandated annual minimum levels of production and maximum levels of GHG emissions. RFS2 would extend to 2022, by which year total production of renewable fuel is targeted at 36 billion gal consisting of the following minimums: 16 billion gal of cellulosic biofuel; a to-be-determined volume of biomass-based diesel of at least 1 billion gal; and 21 billion gal of advanced biofuels. The advanced biofuel category encompasses cellulosic biofuel and biomass-based diesel, plus certain other types of advanced biofuel.
