Europe to Study Indirect Land Use

The European Parliament on Dec. 17 adopted amendments to the Renewable Energy Sources Directive, raising targets for production of biofuels but at the same time setting strict sustainability standards to monitor and reduce greenhouse gas emissions from the use of road transport fuels. The Parliament’s adopted text makes clear that it intends to calculate climate change emissions from international land use, but that the science is not currently available to do so: Whereas (11) In 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 >

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 >

How Much Corn Is in a Barrel of Oil?

A segment on the Discovery Channel’s show “How Stuff Works” caught my eye this week and prompted that question. The segment points out that Xanthan gum, fermented from corn syrup, is used in oil drilling. Xanthan is combined with the drilling mud used to cool drilling equipment, and it helps to clear dirt and rock from the mud as well as maintain a pressure cap on the bore hole. The primary markets for Xanthan gum 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 >
