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. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Source: University of Leicester.

EEA report finds most Europeans in cities still exposed to levels of air pollution exceeding WHO guidelines

Green Car Congress

The European Environment Agency’s (EEA’s) “ Air quality in Europe — 2019 report ” shows that almost all Europeans living in cities are still exposed to air pollution levels that exceed the health-based air quality guidelines (AQGs) set by the World Health Organization (WHO). About 8% of the urban population in the EU-28 was exposed to PM 2.5

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

Green Car Congress

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. CARB has approved additional measures to reduce emissions of greenhouse gases from super pollutants that must also be reduced significantly.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.

Researchers suggest that air quality tests need simplifying to help reduce dangerous emissions

Green Car Congress

New methods of testing and simulating air quality should be considered in order to help policy makers have a more accurate understanding of how emissions affect air pollution levels, new research suggests. The researchers compared current techniques used to describe atmospheric chemical reactions against more historical techniques.
