More Indirect Effects from Oil

In the California Air Resources Board (ARB) hearing on the Low Carbon Fuel Standard, the ARB staff insisted that they looked at the indirect carbon effects of oil but couldn’t find any. In a recent post on this blog, I suggested that they should subscribe to National Geographic Magazine. But that isn’t the only news outlet where they could find evidence of indirect effects. This morning’s EE News had links to several stories detailing indirect Read More >

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 >

A Bad Rule Is Better Than No Rule?

California’s Air Resources Board will vote Thursday on its proposed numbers for the life cycle emissions of various fuels, included under the Low Carbon Fuel Standard. According to a Greenwire story picked up in the New York Times, advocates of the rule believe that it will stimulate investment in advanced biofuels, since according to the staff analysis those biofuels will be preferred for use in California. But start-up advanced biofuel producers are facing considerable economic 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 >
