Vehicles and the Emissions They Produce

How Much Does A Vehicle Emit?

What an individual vehicle emits depends on many factors, including the emission control system on the vehicle, the effectiveness of the control system, the way you drive, and the number of miles you drive.

Throughout the years, manufacturers have designed vehicles and engines to reduce the amount of emissions emitted during its lifetime. A new 1965 car produced about a ton of smog-forming hydrocarbons during 100,000 miles of driving. Standards in the 1990's reduced new car emissions to about 50 pounds of hydrocarbons. By 2010, new cars will emit only about 10 pounds of hydrocarbons in 100,000 miles. The following chart demonstrates the improvements made in emission control.
