Comments on EPA’s Proposed 2013 RFS Volume Requirements
The Clean Air Act allows EPA to reduce the RFS volume requirements for “advanced fuels” and total renewable fuels whenever it downsizes the annual cellulosic biofuel requirement. CATF’s comments explain that EPA needs to take this step in order to avoid further increases in the climate-harming production of corn ethanol…

CATF Comments Urging EPA to Waive the Corn Portion of the RFS
In the midst of the worst drought in decades, CATF submitted comments with ActionAid, Friends of the Earth, and Environmental Working Group urging EPA to waive the portion of the RFS mandate that can be met using corn ethanol in 2012-2013. ActionAid’s report on the financial cost that the US…

Working Paper: A Time Horizon for Counting Bioenergy Emissions
In a working paper funded by CATF, Timothy Searchinger, the lead author of several seminal publications on the climate impact of biofuels, analyzes the appropriate timeframe in which to measure bioenergy’s net GHG emissions. Searchinger concludes that even a 20-year timeframe is generous, and considers the broader implications for bioenergy’s…

CATF Comments on RFS Eligibility of Palm-based Biofuels
CATF’s comments describe how a decision to qualify biofuels derived from palm oil as “renewable fuels” under the RFS would violate EPA’s statutory obligations, particularly its duty to ensure that qualifying fuels provide a reduction in lifecycle GHG emissions. CATF also contributed to a broader set of comments on the…

CATF Comments on RFS Eligibility of Giant Reed, Camelina, and Other Feedstocks
Comments submitted by CATF, EWG, FOE, NWF, and NRDC raise concerns about EPA’s land use change analysis for potential biofuel feedstocks and its failure to adequately address the threats they pose as invasive species. The comments also discuss a recent report on the impacts of corn stover removal in the…

Subsidizing Conventional Biofuels: An Idea Whose Time is Over
Finally, policies that prop up biofuels production are in the crosshairs, and not a moment too soon. Because over the last decade, the biofuels industry has grown accustomed to getting whatever it wants, with no questions asked. Those days, at long last, appear to be over. Last week, the U.S….
