Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

The study used the series production versions launched in 2011, with the assumption of operation for 150,000 km (93,205 miles). Since the BEV version has a shorter range, Renault noted, the way in which the miles are accumulated could differ from that of the ICE vehicles.).

Study finds changes in the Arctic sea ice cover may be driving changes in atmospheric chemistry

Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant. Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface.

Study Finds Asian Monsoon Carries Pollution Into the Stratosphere

Green Car Congress

Those vertical movements provide a pathway for black carbon, sulfur dioxide, nitrogen oxides, and other pollutants to ascend into the stratosphere, about 20-25 miles above the Earth’s surface. This could explain satellite measurements showing high levels of stratospheric ozone, water vapor and other chemicals over Asia during summer.

Research shows clean fuel-use for ships off California coast extremely effective in reducing sulfur dioxide pollution

The researchers also found that every ship in California waters whose emissions were measured was using low-sulfur fuel. The 274-foot research vessel examined the composition of emissions from more than 70 passing ships over 24 days.

The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) There were more than 1,231,000 miles of distribution mains in 2011, an increase of approximately 287,000 miles since 1990. a global warming potential of 21.

Study finds paved surfaces in Houston worsen air quality

Green Car Congress

Houston, with a mix of petrochemical facilities, sprawling suburbs, and traffic jams that stretch for miles, has some of the highest levels of ground-level ozone and other air pollutants in the United States. The article is in press in the Journal of Geophysical Research-Atmospheres , a publication of the American Geophysical Union.

Contributions of regions to total life cycle emissions for three fuels (µg per vehicle-mile traveled per km 2 land area). 60% of ground-level ozone (O 3 ) precursors, 6% of fine particulate matter (PM 2.5 ), and 22% of greenhouse gases (GHGs) emitted.
