CAMBRIDGE, Mass. -- In a study appearing this month in the journal Environmental Science and Technology, MIT researchers report that emissions from cars, trucks, planes and powerplants cause 13,000 premature deaths in the United Kingdom each year.
The researchers analyzed data from 2005, the most recent year for which information is available. They found that among the various sources of emissions in the country, car and truck exhaust was the single greatest contributor to premature death, affecting some 3,300 people per year. By comparison, the researchers note, fewer than 3,000 Britons died in road accidents in 2005.
The researchers found that emissions originating elsewhere in Europe cause an additional 6,000 early deaths in the U.K. annually; U.K. emissions that migrate outside the country, in turn, cause 3,100 premature deaths per year in other European Union nations. In some areas on the periphery of the U.K. such as northern Scotland almost all air pollution comes from the rest of Europe, the researchers say.
MIT's Steven Barrett and his co-author Steve Yim began the study in light of recent events in the U.K.: London is currently in violation of air quality standards set by the E.U., and the British government may face significant E.U. fines if it fails to address its air pollution.
"We wanted to know if the responsibility to maintain air quality was matched by an ability to act or do something about it," says Barrett, the Charles Stark Draper Assistant Professor of Aeronautics and Astronautics at MIT. "The results of the study indicate there is an asymmetry there."

Barrett worked with MIT postdoc Steve Yim to analyze emissions data provided by the British government. The team divided the country's emissions into sectors, including road transport; power generation; commercial, residential and agricultural sources; and other transport, such as shipping and aviation
