In China, people breathe ozone-laden air two to six times more often than people in the United States, Europe, Japan, or South Korea, according to a new international study published in Environmental Science & Technology Letters. 2017 for one ozone metric. The inset shows ozone trends in Beijing (red) and Los Angeles (blue).

Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new study by researchers at NOAA and their colleagues shows. Even more unexpected was that the rate of decline slowed by 50% after 2012.

A study by an international team led by scientists at the University of East Anglia have identified four new man-made gases in the atmosphere, all of which are contributing to the destruction of the ozone layer. They also looked at air collected between 1978 and 2012 in unpolluted Tasmania. Brenninkmeijer, Paul J. Oram, Claire E.

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C °F) by 2050, as well as improving human health and agriculture.

Following this BAU scenario, the researchers projected that air quality for the global average citizen in 2050 would be almost comparable to that for the average citizen in East Asia in the year 2005—an outcome which underscores the need to pursue emission reductions, according to the authors.

NO 2 is just one component of air pollution, which is made up of many pollutants (including particulate matter, ozone, carbon monoxide), which are known to have numerous adverse effects on health. NO 2 is a pollutant formed mainly from fossil fuel combustion, and traffic emissions can contribute up to 80% of ambient NO 2 in cities.

The percent of biodiesel and renewable diesel in the total diesel blend have shown a significant growth in recent years, going from 1% in 2012 to 18% in 2017. Biofuels such as ethanol, biodiesel, and renewable diesel can displace fossil fuels and reduce the amount of fossil-based CO 2 emissions released into the atmosphere.
