Ethanol made from corn grown across millions of acres of American farmland has become the country’s premier renewable fuel, touted as a low-carbon alternative to traditional gasoline and a key component of the country’s efforts to reduce greenhouse gas emissions. But a new study, published this week, finds that corn-based ethanol may actually be worse for the climate than fossil-based gasoline, and has other environmental downsides. “We thought and hoped it would be a climate solution and reduce and replace our reliance on gasoline,” said Tyler Lark, a researcher with the Nelson Institute for Environmental Studies at the University of Wisconsin, Madison, and lead author of the study. “It turns out to be no better for the climate than the gasoline it aims to replace and comes with all kinds of other impacts.” - Inside Climate News
