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.

Yale study finds asphalt a significant source of air pollution, especially on hot, sunny days

Green Car Congress

Asphalt is a near-ubiquitous substance—it’s found in roads, on roofs and in driveways—but its chemical emissions rarely figure into urban air quality management plans. Asphalt’s life cycle and temperature-dependent emissions. (A) At typical temperature and solar conditions simulating different life cycle stages (i.e.,

However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols.

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

For example, states in the western US (WUS) generally produce a larger fraction of their electricity from renewable and/or “emission-free” sources (i.e., solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e.,

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet. cancel the launch. “The
