How to Compare Unleaded Gas & Diesel Fuel Carbon Emissions

Green-minded consumers may wish to compare the carbon footprint of gas and diesel vehicles before making an informed decision about which one to buy. Generally speaking, diesel engines emit fewer greenhouse gas emissions primarily because they get better fuel economy than their gasoline counterparts. The U.S. Department of Energy and the U.S. Environmental Protection Agency have partnered to offer a useful online search engine that allows consumers to compare the carbon footprints of many of today's most popular vehicles. This tool can be used to compare the carbon footprint of diesel and gasoline engines for many specific makes and models.
