Overview of Regulation Specifications
* Assumes manufacturers fully use A/C credit** Proposed CAFE standard by NHTSA. It is equivalent to 163g/mi plus CO2 credits for using low-GWP A/C refrigerants.“** In April 2010, Canada announced a target of 153 g/km for MY2016. Value in brackets is estimated target for MY2016, assuming that during
2008 and 2016 the fuel efficiency of the LDV fleet in Canada will achieve a 5.5% annual improvement rate (the same as the U.S.). This estimate is used in the accompanying charts.
Total and annual percentage CO2 reduction with enacted and proposed targets
Regions are ordered according to their overall improvement/reduction rate.
** Baseline year for each regulatory period is the first year of that period. For example, the US overall reduction rate is 17% for the MY 2012-2016, and 35% for MY 2017-2025 . One cannot combine 17% and 35% to get the overall reduction rate from 2012 to 2025.
Total and annual percentage fuel economy improvement with enacted and proposed targets
Regions are ordered according to their overall improvement/reduction rate.
** Baseline year for each regulatory period is the first year of that period. For example, the US overall reduction rate is 15% for the MY 2012-2016, and 46% for MY 2017-2025 . One cannot combine the two values to get the overall reduction rate from 2012 to 2025.
