Ca driver had a good article explaining the details about emissions standards from around the world.

Another standard that affects all vehicles and emissions is average fuel economy. Currently in the U.S., Corporate Average Fuel Economy (CAFE) standards are proposed to increase by 40 per cent by the year 2020 to an industry average of 35 mpg (U.S.), which is approximately equal to about 6.7 L/100 km. In the U.S., this is based on the vehicle class or "footprint". By contrast, in Europe this is based by vehicle weight. Japan uses a completely different "Top Runner" approach, where the best vehicle in each class is used as the benchmark, to provide incentive to those not meeting the standards of the best.
