“EPA released its annual report that tracks the fuel economy of vehicles sold in the United States, underscoring the major increases made in the efficiency of the vehicles Americans drive, reducing oil consumption and cutting carbon emissions. According to the report, EPA estimates that between 2007 and 2012 fuel economy values increased by 16 percent while carbon dioxide (CO2) emissions have decreased by 13 percent, and in 2012 alone the report indicates a significant one year increase of 1.4 miles per gallon (mpg) for cars and trucks.”
