The resolution of local and regional air pollution problems requires the development of an appropriate scientific and decision-making framework within which effective air quality management may be undertaken.

Drawn from nine countries around the world - Argentina, Australia, Colombia, India, Iran, Italy, Mexico, the United Kingdom and United States - this collection of case studies describes the development and implementation of selected aspects of local or regional management frameworks and/or measures adopted in the pursuit of achieving and sustaining acceptable air quality. Identifying aspects that are particularly successful will help assess the potential for transferability of approaches between nations.
