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.

Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

In the Tianjin study, they team fueled a four-cylinder light-duty diesel engine fueled with CFT and DF, identifying 13 individual carbonyl compounds in the exhaust. Under the engine operating conditions used, formaldehyde and acetaldehyde were the dominant carbonyl compounds for both test fuels. Jakober, 2008). CFT had 16.5–44.1%

Airborne measurements show ozone-forming VOCs emissions from ethanol plant higher than government estimates

Green Car Congress

New airborne measurements downwind from an Archer Daniels Midland fuel ethanol plant in Decatur, Illinois, show that ethanol emissions are 30 times higher than government baseline estimates. VOCs and nitrogen oxides react with sunlight to form ground-level ozone, the main component of smog. —Joost de Gouw.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate. The burning of coal releases more carbon dioxide than other fossil fuels, as well as comparatively high levels of other pollutants, including sulfur dioxide, nitrogen oxides, and particles such as ash.

Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

Green Car Congress

Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and ventilation air from coal mines. Extraction and transport of fossil fuel. for 2030 and beyond.

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

Green Car Congress

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.
