Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. This is contrary to what is typically assumed and suggests a new way to mitigate this type of pollution in Salt Lake City, Denver and beyond. Denver often has the same problem in winter, when brown clouds hang over the city.
