Environmental Groups Pressure EPA to Calculate Indirect Emissions

The latest salvos on the EPA’s rulemaking process for the Renewable Fuel Standard come from six major environmental groups – the Environmental Defense Fund, National Wildlife Federation, Natural Resources Defense Council, Friends of the Earth, Union of Concerned Scientists, and Environmental Working Group – and academics at the University of California Berkeley. In their letter to EPA Administrator Stephen Johnson, the environmental groups argue that delaying conclusions about which biofuels make the grade under the Read More >

EPA Gets Input on Sustainable Biofuels

On Monday Oct. 27, the EPA’s Science Advisory Board held a workshop in Washington on “Looking to the Future.” The stated purpose of the workshop was “to stimulate SAB thinking about priorities for meeting critical environmental problems with an integrated approach to interdisciplinary science and research” and gather data on the net environmental implications of biofuels. A number of experts on biofuels and agriculture gave SAB presentations on land use change and other possible climate Read More >

Clouding Assumptions

Science magazine this week published an exchange between Vinod Khosla, the venture capitalist who has invested a great deal in alternative energy, and Timothy Searchinger and coauthor Richard Houghton critiquing and defending the February 2008 study, “Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land-Use Change” The exchange reveals some of the nuances of indirect land use change arguments that have not been addressed. Khosla’s comments raise two important issues, allocation Read More >

EPA Drafting Rules on International Land Use Change

The U.S. EPA is expected to release a proposed rulemaking for implementing the lifecycle analysis requirements for biofuels under the renewable fuels standard. (Check out the EPA’s official blog, even though it contains no posts on this subject.) Estimating the emissions generated through the production of biofuels has been controversial, particularly with respect to how land-use changes affect emissions. E&E TV’s OnPoint recently interviewed Jack Huttner, vice president of Dupont Danisco Cellulosic Ethanol, about the Read More >

This Week in Science

A group of preeminent academics put forward a policy proposal on regulating the development of cellulosic biofuels in the pages of Science magazine last week. They point out the urgent need to think about the unintended consequences of alternative fuels in order to achieve outcomes that are substantially better than “business as usual.” They conclude: Legislated environmental performance standards for cellulosic ethanol production could, for example, go far towards promoting sustainable outcomes. Such standards could Read More >
