The journal Science published two papers:
- Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land Use Change
in their online, early publication ScienceXpress that suggest that the production and use of biofuels may be worse for climate change than gasoline. The study and papers argue that cultivating more land to produce biofuels will create a “carbon debt” that has to be repaid. The conclusion they draw is that it is better to continue to use petroleum for transportation fuel. A careful and balanced analysis suggests that such a sweeping statement is not justified by the evidence. Much has been made of these papers both in the conventional media and in the blog world. We hope that by launching this space for conversation that we can begin to get at the truth. Drop in and let us know what you think.
