New analysis has found increasing emissions of several ozone-depleting chemicals despite their production being banned for most uses under the Montreal Protocol—and a loophole in the rules is likely responsible. According to the researchers, emissions from these CFCs currently do not significantly threaten ozone recovery.

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5

They found that the increase in ozone burden due to the spatial distribution change slightly exceeds the combined influences of the increased emission magnitude and global methane. Based on their findings, they suggested that emission increases in Southeast, East and South Asia may be most important for the ozone change.

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.

Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.

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. Emission increases of this scale have not been seen for any other CFCs since controls were introduced during the 1990s.
