Global study links daily exposure to ozone pollution to increased risk of death

Green Car Congress

Daily exposure to ground level ozone in cities worldwide is associated with an increased risk of death, according to the largest study of its kind, published in an open-access paper in The BMJ. Ground level ozone is a highly reactive gas commonly found in urban and suburban environments, formed when pollutants react in sunlight.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Researchers report on potential long-range atmospheric emissions impacts of increased ethanol fuel use in North America

Green Car Congress

Seasonal ethanol emissions from North America. Emissions for present-day are compared to those for the EISA and All-E85 scenarios. However, the significance of this effect will depend on the size of the emission change compared to that of the existing source fluxes, which are poorly known. Labels at left are months (e.g.,
