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 >

New Studies Question Cellulosic Biofuels
A new study from MIT’s Joint Program on the Science and Policy of Global Change examines what it calls the Unintended Environmental Consequences of a Global Biofuels Program. Unintended consequences seems to be the watchword of the year. The authors posit that there will be a feedback loop from climate change and policies that promote biofuels to address it. Climate change itself will affect the productivity of land, shifting agricultural production to new areas, and Read More >
