Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

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).

coal, oil, natural gas, and biomass). 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.
