LANSING — New research suggests increased ethanol fuel use could be dramatically reducing greenhouse gas emissions in Michigan. A study by scientists at Michigan State University shows ethanol use in the state is reducing carbon dioxide emissions by nearly 1.4 million metric tons each year, the equivalent of emissions from 294,000 cars. Ethanol fuel production, meanwhile, has nearly doubled in the past seven years, from 276 million gallons in 2007 to 452 million in 2012. The findings suggest ethanol could serve as one tool to slow global warming, experts said. “We can reduce some portions of greenhouse gas if we use more ethanol,” said Seungdo Kim, a chemical engineering and materials science professor who coauthored the study.
