Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels.

Study Links Springtime Ozone Increases Above Western North America to Emissions in Asia

Green Car Congress

Springtime ozone distributions for 1984, 1995–2008 in the mid-troposphere (3.0–8.0 Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia. The US EPA recently proposed new tougher ground-level ozone standards.

Study first to quantify amount of US pollution resulting from Chinese manufacturing for exports

Green Car Congress

Chinese air pollution blowing across the Pacific Ocean is often caused by the manufacturing of goods there for export to the US and Europe, according to findings of a new study to be published this week in the Proceedings of the National Academy of Sciences (PNAS).

Study finds paved surfaces in Houston worsen air quality

Green Car Congress

The international study could have implications for the air quality of fast-growing coastal cities in the United States and other mid-latitude regions overseas—the proliferation of strip malls, subdivisions, and other paved areas may interfere with breezes needed to clear away smog and other pollution. and lead author.

Why Schools Should Electrify Their Bus Fleets

Blink Charging

While it’s obvious that the internal combustion engine vehicles are polluting the air outside the buses, what you may not know is that numerous studies show that the pollution from the burning diesel regularly makes its way into the buses.

Study Finds Asian Monsoon Carries Pollution Into the Stratosphere

Green Car Congress

Arrows denote winds at this level derived from meteorological analysis, showing that the HCN maximum is linked with the upper tropospheric Asian monsoon anticyclone. This could explain satellite measurements showing high levels of stratospheric ozone, water vapor and other chemicals over Asia during summer. Source: Randel et al.,
