Pollution Facts from the Foundation For Clean Air Progress
- It would take 20 of today's new cars to generate the same
amount of air pollution as one mid-1960's model car. In another
10 years, thanks to new automotive and fuel technologies, it will take
33 cars to produce the air pollution emissions of one mid-1960s model.
- One major air pollutant, lead, is nearly gone from our air.
Since the mid-1970's, levels of airborne lead are down 96
percent. Despite these facts, there's still room for
improvement. Everyone can help make a difference in this effort.
- Reducing the use of the air conditioner in your car will continue
to reduce the air pollution you create.
- Added weight makes your car's engine run less efficiently,
increasing air pollution.
- Between 1980 and 1999, a 43 percent reduction in the three-year
average number of air pollution exceedance days was observed.
