A new generation of biofuels, meant to be a low-carbon alternative, will on average emit more carbon dioxide than burning gasoline over the next few decades, a new study finds. "In the near-term I think, irrespective of how you go about the cellulosic biofuels program, you're going to have greenhouse gas emissions exacerbating the climate change problem," said lead author Jerry Melillo of the U.S. Marine Biological Laboratory.
