TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. In some parts of Asia, Africa and South America, the researchers identified data gaps which prevented them from characterizing ozone pollution exposure patterns. Source: University of Leicester.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

The data shows a slight increase in overall emissions from the previous year, and a slight decline in emissions from transportation, which is the state’s main source of both GHGs and air pollutants. CARB has approved additional measures to reduce emissions of greenhouse gases from super pollutants that must also be reduced significantly.

Evidence from glacier ice: Until it was banned, leaded gasoline dominated the anthropogenic lead emissions in South America

Green Car Congress

Leaded gasoline was a larger emission source of the toxic heavy metal lead than mining in South America, even though the extraction of metals from the region’s mines historically released huge quantities of lead into the environment, according to a study by researchers from the Paul Scherrer Institute PSI and the University of Bern.

Study finds that replacement programs that reduce vehicle lifetime can result in increased lifecycle CO2 emissions

Green Car Congress

Effects of changes in the average lifespan of ordinary passenger cars newly registered between 1990-2000 on total induced CO 2 emissions in 2000. They also found that extending the lifetime of a vehicle contributed to a moderate increase in emissions of criteria pollutants (NO x , HC, and CO) during the use phase of the vehicle.
