America’s Lowest Carbon Footprint Cars

Tesla is the leading plug-in seller this year. The company does not believe hybrids are a good solution, and eschews gasoline. According to the U.S. Energy Information Administration (EIA), burning one ethanol-free gallon of gasoline produces about 19.64 pounds of CO2. One gallon of diesel yields about 22.38 pound of CO2 but diesel engines usually offset this by yielding increased fuel economy.
