The March 15 report [attached] finds that the adjusted composite CO2 emissions from vehicles for model year 2012 have fallen to 374 grams per mile (g/mi), with fuel economy levels rising to 23.8 miles per gallon (mpg). “Based on preliminary estimates, CO2 emission rates have decreased by 13 percent and fuel economy values have increased by 16 percent from MY 2007-2012. The improvements have been even greater since the ‘inflection point’ year in 2004,” the report says…
