Vehicle emissions

In Auckland in 2003, scientists monitored pollutants from the exhaust of passing vehicles. Emissions were rated as good, fair or poor, and the ratings were displayed on a sign for drivers to see. A small proportion of cars were responsible for most of the pollution. Cars are a major source of urban air pollution.
