Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. Their study is published in Proceedings of the National Academy of Sciences (PNAS).

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The team studied 89 healthy adults living in Changsha City, China, for one year.

Most studies that have examined the impact of EVs report only changes in the total emissions associated with their adoption, but do not consider their spatial or temporal variation. Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels.

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

AUGUST 21, 2009

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? Research takes a long time.
