Don’t Worry, Be Happy
The EPA has released its long-awaited proposed rules for the Renewable Fuel Standard, including calculations of the lifecycle greenhouse gas emissions for various biofuels. Unlike California, the EPA is proposing to “discount” the greenhouse gas emissions of both biofuels and the baseline petroleum gasoline. The discount rate that EPA uses for most of the calculations it presents is 2 percent over 100 years, although it also proposes using a 0 percent discount rate and a Read More >

EPA Ready to Release Rules for RFS
The White House Office of Management and Budget has completed its review of the EPA’s rules for the Renewable Fuel Standard, which will contain the lifecycle analysis for U.S. fuels. Reuters and the Des Moines Register have reported on the significance of the rule, though EPA has not made clear when the rule will be published in the Federal Register, beginning the comment period. The rule, much like California’s Low Carbon Fuel Standard (CARB), will Read More >

Best Available Science?
Yesterday, the Scientific Committee on Problems of the Environment (SCOPE) released a report, “Biofuels: Environmental Consequences and Interactions with Changing Land Use,” based on the proceedings of its International Biofuels Project Rapid Assessment. The Environmental Working Group immediately praised the report, claiming that it “confirms that corn-based ethanol is a dead end.” (I recommend reading this response to EWG by Biofuels Digest’s Jim Lane.) Far from that confirmation, the report’s recommendations recognize that whether the Read More >

Controversy on Discounting Greenhouse Gas Emissions
On March 13, Sens. Tom Harkin (D-Iowa) and Charles Grassley (R-Iowa) along with 10 others sent a new letter to EPA Administrator Lisa Jackson urging “EPA to refrain from including any calculations of the ILUC components in determining life-cycle GHG emissions for biofuels at this time.” The new letter referenced a letter sent in November to then-Administrator Stephen Johnson, which was signed by four of the current 12 signers as well as then Sen. (now Read More >

New Studies Support Cellulosic Ethanol
A team of researchers led by Jason Hill and David Tilman at the University of Minnesota have published an interesting assessment of the health costs of both greenhouse gas and fine particulate matter from corn ethanol, gasoline and cellulosic ethanol. The study is available in the Proceedings of the National Academy of Sciences early release for Feb. 10. The conclusion is favorable to cellulosic ethanol: The benefits of shifting from gasoline and the current generation Read More >
