It’s Carbon Payback Time

A recent study from researchers at the University of Wisconsin takes another look at the “carbon debt” models proposed by Searchinger and Fargione in ScienceXpress earlier this year. Searchinger and Fargione argued that biofuel development in the United States and Europe would lead to the destruction of rainforests and grassland in Brazil and other tropical climates, which would of course release massive amounts of carbon into the atmosphere (See earlier posting). The new study takes Read More >

British Government to Study Indirect Impacts of Biofuels

Last week, Britain’s Renewable Fuels Agency (RFA) launched a series of studies of the indirect land-use impacts of biofuels, following a lecture by Princeton’s Tim Searchinger, lead author of “Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land Use Change” published in Science in February. The RFA intends to publish a draft report in May, prior to negotiation of EU-wide biofuels targets to 2020 in Brussels later this year. Britain is set Read More >

An Interesting Coincidence?

The papers published in Science two weeks ago continue to make headlines, as a quick search of Google News will show. Also this week, oil reached the $100 per barrel mark. Meanwhile, debate over the Science papers continues, and some truths are out there, as we said when we began this public forum. Nathanael Greene of the Natural Resources Defense Council notes the media have made rather simplistic assessments of the Science papers.Greene writes that the Read More >
