The need to clean up the air in Asia is growing more urgent. Urban air pollution is causing more than 530,000 premature deaths in Asia annually, according to a study by the World Health Organization.

To clean up the air, we must clean up our fuels. Smoke from vehicles is a major source of pollution. Vehicles emit pollutants such as carbon dioxide, sulfur dioxide, particulate matter, and nitrogen oxide, among others. These pollutants will increase in levels as vehicle volumes rise in Asian cities.

This publication showcases how the Clean Air Scorecard can help cities in Asia comprehensively assess air pollution levels and air quality management capacity.
