Texas study finds PHEV use could increase ozone at night, decrease ozone during the day

Green Car Congress

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours.

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.

Study finds global emissions of ethane and propane underestimated by more than 50%

Green Car Congress

When ethane and propane—the most abundant non-methane hydrocarbons (NMHC) in the atmosphere—mix with nitrogen oxides from vehicles and power plants they form tropospheric ozone—a key component of smog and directly linked to increases in mortality. —Professor Ally Lewis, a co-author of the study.

Study: 25% EV adoption would save US $17B annually from avoided climate change & pollution damages

Green Car Congress

Although the impact of carbon emissions on the climate is well documented, combustion engines also produce other harmful pollutants, such as particulate matter and the precursors to ground-level ozone. After leaving tailpipes and smokestacks, pollutants interact with their environment, influencing atmospheric chemistry and meteorology.

Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

This research points to the importance of two fundamental and parallel trends in energy and the environment. Considering the electric power sector and transportation sectors together, net emissions of pollutants leading to atmospheric ozone and fine particulate matter (PM 2.5 ) decrease in the electrification scenario.

UN Review of Recent Climate Research Concludes That Impacts Of Climate Change Coming Faster Than Anticipated

Green Car Congress

The report released by the United Nations Environment Programme (UNEP), entitled Climate Change Science Compendium 2009 , highlights new research that identifies some events thought likely to occur in longer-term time horizons as already happening or set to happen far sooner than had previously been thought.
