With nearly 250 million light duty vehicles on the road, the United States has the largest vehicle fleet in the world, and annual new vehicle sales second only to China.

Despite its historical role in pioneering vehicle regulations, from the mid-1980s until very recently the U.S. lagged behind other developed nations in passenger vehicle fuel economy standards and emissions regulations (see the global PV standards update), with higher levels of CO2 emissions per mile, higher average fuel consumption, and lower average fuel economy. However, since 2009 the United States has adopted aggressive legislation that could make the country a global leader in fuel efficiency and GHG emissions control. And market demand for fuel-efficient gasoline, hybrid, and electric vehicles is growing.

Vehicle and fuel standards can dramatically reduce air pollution in Brazil, São Paulo’s air quality data demonstrate
Implementing P-8 (Euro VI-equivalent) standards for trucks and buses might be the most cost-effective way to improve air quality, not just in São Paulo but nationwide. The benefits associated with P-8 standards outweigh their costs by a ratio of 11 to 1.
