Modelling the Impact of PHEVs on Ozone in Denver

Green Car Congress

Denver represents an interesting case study for exploring potential PHEV impacts because it violates the federal air quality standard for ozone and because several large EGUs [electricity generating units] are located in or near the urbanized area. million vehicles and would have increased by 3 tpd from power plants.

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Two maps compare total annual sulfur dioxide amounts for India and China during 2005 (left) and 2016 based on Ozone Monitoring Instrument measurements. Most of the two countries’ sulfur dioxide emissions come from coal-fired power plants and coal-burning factories. Note the decrease in size of the purple region over northeastern China.

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. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.
