The EPA says that the final 2014 model year “adjusted” real world CO2 emissions (+20% higher than the emissions test used) for all new, personal vehicles is 366 g/mi, unchanged from 2013. The 2014 model year adjusted (-20% lower) fuel economy is 24.3 mpg, which is also unchanged from 2013. New vehicle CO2 emission rates remain at the lowest rate ever recorded in the so-called Historical Trends database, and likely the lowest rate of all-time. New vehicle fuel economy is correspondingly at the highest level ever recorded, and likely the highest of all-time.
