This report reviews new vehicle fuels and technologies that are likely to be commercially available within the next 10 years in the United States and other industrialized countries at a level that could result in significant population exposure.

This report is the first comprehensive literature review to come out of HEI's Public Health and Air Pollution in Asia (PAPA) program. The review builds on an initial assessment conducted in 2004 and describes the current scope of the Asian literature on the health effects of outdoor air pollution, enumerating and classifying more than 400 studies.

Motor vehicles are a significant source of urban air pollution and are increasingly important contributors of anthropogenic carbon dioxide and other greenhouse gases.
