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 >

Midnight Rule
The EPA apparently missed the statutory deadline (Dec. 19) to publish the Notice of Proposed Rulemaking for the Renewable Fuel Standard. The Bush administration last summer announced that it would not promulgate new rules during its final 30 days, in order to stay away from “midnight rulemaking.” That self-imposed deadline (Dec. 20) also passed. The rule is said to be a victim of lobbying on the part of the biofuel industry and environmental groups. Marianne 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 >

Does Oil Cause Indirect Land Use Change?
I’ve been paying a lot of attention recently to new analyses attempting to model carbon emissions from indirect land use change, which is the conversion of land needed to maintain an international balance of supply and demand for agricultural crops, an effect that is heavily determined by crop prices. These new analyses raise a question about the existing assumption that oil has zero effect on land use change. Tim Searchinger, the lead author of one Read More >

More Models to Measure Land Use Change
As the U.S. EPA and California’s Air Resource Board seek to implement their respective Renewable and Low-Carbon Fuel Standards, economists continue to refine models to measure and predict indirect land use change emissions associated with biofuels. Many of the original critiques of the Searchinger paper in Science that initiated this debate commented on the uncertainty in attributing indirect land use change to biofuels. Prof. Roger Sylvester-Bradley of ADAS UK Ltd., for instance, summarizes many of Read More >
