Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

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 Finds Current Swedish Biofuels Offer Major Climate Benefits; Biogas from Manure the Best

Green Car Congress

A study by researchers at Lund University in Sweden found that Swedish biofuels produce between 65 and 148% less greenhouse gas emissions than gasoline and diesel, even when direct and indirect land use changes are taken into account. There is room for all, and all are needed to develop alternatives to fossil fuels.
