About 150 million people live in counties where
monitored air pollution levels in 2007 reached unhealthy levels.
Highway vehicles are a major contributor to
air pollution in the U.S., producing 26-62% of key chemicals
that cause smog and health problems.
- Carbon monoxide (CO) - 62%
- Nitrogen oxides (NOx) - 36%
- Hydrocarbons - 26%
All new cars must meet federal emissions standards,
but as vehicles get older, the amount of pollution they produce
increases. Therefore, vehicles with better fuel economy may
pollute less than those with lower fuel economy.
