New study links air pollution in one location to deaths elsewhere

Signal of change / New study links air pollution in one location to deaths elsewhere

Published in the journal Nature, the article "Transboundary health impacts of transported global air pollution and international trade" describes an innovative attempt to make sense of and measure how air pollution in one place may lead to deaths in another. The study looks at both atmospheric transmission of PM2.5 emissions, as well as how consumption in one part of the world generates emissions in another part of the world. The study finds that 12% of PM2.5 related deaths in 2007 were related to emissions generated somewhere else - and that 22% of those deaths were driven by consumption in other parts of the world.

So what?

This new way of illustrating the global dimension of emissions will hopefully lead to more approaches and transform the way policymakers, particularly in developed countries with high environmental standards, consider their frame of reference to air pollution policymaking.

What might the implications of this be? What related signals of change have you seen?
