UB study finds link between ambient ozone exposure, artery wall thickness

Green Car Congress

Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. The study found that chronic exposure to ozone was associated with a progression of thickening of the main artery that supplies blood to the head and neck.

EPA issues emergency fuel waiver for E15 sales

Green Car Congress

The Clean Air Act (CAA) requires the use of low-volatility gasoline during the summer months in order to limit the formation of ozone pollution. The Clean Air Act allows the EPA Administrator, in consultation with the US Department of Energy (DOE), to waive certain fuel requirements temporarily to address shortages.

Study Concludes Warming Climate Will Increase Ozone Levels in Major California Air Basins; Climate Change and Regional Air Quality Are Intertwined Problems

Green Car Congress

Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. We already know that climate change will bring us increased forest fires, shorter winters, hotter summers and impact our water supply.

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

Green Car Congress

Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels. Locations with clean energy sources, however, saw reductions. Schnell et al.

These were shown to be ozone-depleting, however, and were targeted for phasing out under the 1987 Montreal Protocol. However, HFC-134a, while having zero ozone-depletion potential, has a very high global warming potential—more than 1,500 times as much warming as an equivalent amount of CO 2.
