How Green Is That Biofuel? Depends on Where It Came From #ceres11

CAMBRIDGE, MA — Airline companies like Virgin and Continental have been testing biofuel alternatives to jet fuel to reduce their dependence on oil and limit greenhouse gas emissions. In some cases, though, it's possible for biofuels to have a larger carbon footprint if the land they came from had been drastically converted. Researchers at the Massachusetts Institute of Technology looked at the life cycle GHG emissions related to 14 conventional fuels and biofuels, taking into account different land use change scenarios, and recently published their findings on Environmental Science and Technology's website. For the most part, biofuels come out on top. But a few bring with them bigger footprints. Palm oil that comes from forests or rainforests that were clear-cut, and soy oil from former rainforests can cause up to 10 times more carbon emissions than jet fuels. The research...
