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. There was so much particulate matter in Chinese cities that it stunted the ozone production.

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

Green Car Congress

Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor. Sand et al. A global warming potential of 11.6 Skeie, R.B.,

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

Green Car Congress

Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said. Full implementation of these measures would reduce future global warming by 0.5 °C

Japan Researchers Use Liquefied DME to Extract Oil from Algae at Room Temperature at High Yield

Green Car Congress

Researchers at Japan’s Central Research Institute of Electric Power Industry (CRIEPI), in a project funded by the New Energy and Industrial Technology Development Organization (NEDO), have successfully developed a method to extract oil from algae using liquefied dimethyl ether (DME) at room temperature in high yield.

(The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) In 2011, CH4 emissions from coal mining were 63.2 From 1990 to 2011, CH4 emissions from landfills decreased by 44.7 30.3%), with small increases occurring in some interim years. Tg CO 2 Eq.,
