The Truth is Out There

The journal Science published two papers: Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land Use Change Land Clearing and the Biofuel Carbon Debt 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 Read More >
