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 >

California Proposes Numbers for Indirect Land Use Change Emissions

California issued a staff report last week for its “Proposed Regulation to Implement the Low Carbon Fuel Standard.” As expected, the rule proposes a measure of indirect land use change emissions for select biofuels – corn and sugarcane ethanol and soy biodiesel. The report defines the assumptions behind the analysis – in a word, that use of existing crops for biofuels reduces supplies, increases prices, and thereby induces agricultural expansion: Land use change effects occur Read More >

I Say Sustainable, You Say…

The Guardian newspaper reported last week that environmental activist and reporter George Monbiot had successfully petitioned Britain’s Advertising Standards Authority (ASA) to ban an ad containing the tagline, “Biofuels — A Lower-Priced, Sustainable Answer to OPEC’s Oil.” The ad was sponsored by the Renewable Fuels Association, the Canadian Renewable Fuels Association, the European Bioethanol Fuel Association, and the Brazilian Sugarcane Industry Association. Though Monbiot’s petition is not publicly available, the ASA’s adjudication response indicates it Read More >

Yes, Virginia

One of the most strikingly circular arguments put forward to support inclusion of current estimates of indirect land use change emissions in both California’s Low Carbon Fuel Standard and the EPA’s Renewable Fuel Standard Life Cycle Assessment is that these estimates are so large. The University of California Berkeley Letter to EPA from Michael O’Hare et al. and the previous letter to California’s Air Resources Board by the same group (Mark Delucchi et al.) are Read More >

Discounting the Future of Biofuels

It appears that global leaders’ faith in energy technologies that can reduce greenhouse gas emissions compared to oil is waning, particularly for biofuels, as reported in GreenInc. Respondents to the survey, which included 1,000 environmental experts, ranked energy conservation and efficiency technologies as having the greatest potential impact, both short- and long-term. Some 44 percent of respondents also said they expect that the current economic crisis will hinder progress toward an effective international climate agreement. Read More >
