Study: traffic density, wind and air stratification influence concentrations of NO2

Green Car Congress

However, weather also has an influence on NO 2 concentrations, according to a study by the Leibniz Institute for Tropospheric Research (TROPOS), which evaluated the influence of weather conditions on nitrogen dioxide concentrations in Saxony 2015 to 2018 on behalf of the Saxon State Office for Environment, Agriculture and Geology (LfULG).

Study: plant roadside hedges rather than trees to combat near-road pollution

Green Car Congress

Urban planners should plant hedges—or a combination of trees with hedges—rather than just relying on roadside trees if they are most effectively to reduce pollution exposure from cars in near-road environments, according to a new study from the University of Surrey.

MIT study finds real-world NOx from diesels cars in Europe greatly exceeds laboratory levels; transboundary emissions cause 70% of health impacts

Green Car Congress

A new study by MIT researchers, published this month in Atmospheric Environment , finds that in Europe, 10 major auto manufacturers produced diesel cars, sold between 2000 and 2015, that generate up to 16 times more NO x emissions on the road than in regulatory tests—a level that exceeds European limits but does not violate any EU laws.
