Study: Cellulosic Ethanol Better For Environment -- And Health

The study finds that cellulosic ethanol has fewer negative effects on human health because it emits smaller amounts of fine particulate matter, an especially harmful component of air pollution. Earlier work showed that cellulosic ethanol and other next-generation biofuels also emit lower levels of greenhouse gas emissions.

The study will be published in the journal Proceedings of the National Academy of Sciences in February and will be posted online next week.
