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. Denver often has the same problem in winter, when brown clouds hang over the city.

Modelling the Impact of PHEVs on Ozone in Denver

Green Car Congress

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. Ozone concentration increases were modeled for small areas near central Denver.

California Assemblymembers introduce bill phasing out gasoline-fueled small off-road engines

Green Car Congress

Today, operating the best-selling gas-powered commercial leaf blower for one hour emits air pollutants comparable to driving a 2017 Toyota Camry from Los Angeles to Denver. It’s time to phase out these super polluters. Smog-forming emissions from small engines will surpass those from passenger vehicles this year.

NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

New NASA satellite images released this week demonstrate the reduction of air pollution across the US. Nitrogen dioxide is one of the six common pollutants regulated by the US Environmental Protection Agency (EPA) to protect human health. It’s also a good proxy for the presence of air pollution in general.
