GHG levels from the MY 2016 fleet-wide average of 250 g/mi, using different technology pathways to achieve the reductions. The 2025 targets analyzed thus range from 190 g/mi (equivalent to 47 mpg under test) under the 3% per year reduction scenario to 143 g/mi (equivalent to 62 mpg under test) under the 6% per year scenario.

Using this approach, they found that converting a fleet of cars from gasoline to CNG would result in decades of more rapid climate change because of greater radiative forcing in the early years after the conversion. Hamburg (2012). This would eventually be offset by a modest benefit. Alvarez, Stephen W. Pacala, James J. 1202407109.
