Vehicular Air Pollution: Experiences from Seven Latin American Urban Centers.

Air pollution caused by motor vehicles is a major environmental problem in many Latin American urban centers. If appropriate measures are not taken soon, vehicular air pollution in the region is likely to worsen, posing a great threat to human health and welfare. This report analyzes the pollutants emitted by motor vehicles, their effects, and pollutant-control measures targeted at vehicles, fuels, and transport management. Case studies for Mexico City, Mexico, Santiago, Chile, São Paulo, Brazil, Belo Horizonte, Brazil, Buenos Aires, Argentina, Rio de Janeiro, Brazil, and Santafé de Bogotá, Colombia, illustrate how these measures have been used in the region and how they can be strengthened.
