Does fuel economy translate into less air pollutants?
• 1 of 8 by Kenneth Brown Fuel economy has many components. Some of them are trade offs and some may actually be real.For example, if your car drove at 30 miles per gallon when it was new and now at 100,000 miles it is only getting 25 miles per gallon read more • 2 of 8 by B. B. James Better fuel economy does reduce air pollutants, but the ratio of benefits is not a straight line. In other words, a 20% increase in fuel economy does not equate to a 20% reduction in pollutants. The gain is somewhat less.
