CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Sand et al. —Dr Sand The GWP100 of hydrogen. Sand et al.

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).

China study connects ozone pollution to cardiovascular health

Green Car Congress

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.

UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

Widespread implementation is achievable with existing technology but would require significant strategic investment and institutional arrangements, the study found. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change.

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.
