Motor vehicle emissions harm public health and the environment. The ICCT estimates that exposure to vehicle emissions in the year 2005 produced at least 242,000 global early deaths. Emissions of fine particulate matter, ozone-precursors, air toxics and other harmful pollutants also produce environmental damage in the form of crop fertility losses and near-term climate warming.
