2000 May Report of the Commissioner of the Environment and Sustainable Development
Exhibit 4.7—Ever-Increasing Number of Vehicles on the Road
Transportation in Canada is one of the largest contributors to poor air quality. The transportation sector includes around 17 million cars and light trucks, or roughly one passenger vehicle for every two Canadians. While cars are becoming lighter, more fuel-efficient and less polluting, the increasing number of vehicles on the road erodes the benefits of improved technologies. Vehicles in urban areas are a significant source of smog-causing pollutants, particularly NOx, VOC and CO. Diesel vehicles are also responsible for a significant percentage of particulate matter in urban air.
