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. A key control strategy is to reduce emissions of the limiting reagent.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Automotive emissions of VOCs have decreased steadily from efforts to control tailpipe emissions in the United States and Europe.

Study finds power law scaling relationship between urban population and NO2 pollution

Green Car Congress

A study by NASA scientists and their colleagues at Dalhousie University (Canada) and NOAA based on satellite data has found a significant correlation of surface nitrogen dioxide (NO 2 ) with population in the three countries and one continent examined: United States (r = 0.71), Europe (r = 0.67), China (r = 0.69), and India (r = 0.59).

We are already seeing a transition in America’s roads with over 30% of the trucks and buses in use today meeting these new standards and the trend is growing in Europe as well. Countries like China are already moving toward implementing the ultra-low sulfur diesel fuel that is required for these new cleaner technologies.
