A study warns that manufacturing processes for alternative compounds to chlorofluorocarbons (CFCs), used in aerosols and refrigeration, are directly harming

A study published today in the journal «Nature Geoscience» warns of a increase in harmful gas emissions for the ozone layer due to the manufacturing processes of alternative compounds to chlorofluorocarbons (CFC), used in aerosols and refrigeration.

Researchers from the University of Bristol (United Kingdom) and the US National Oceanic and Atmospheric Administration (NOAA) indicate in their work that the production of these harmful gases is considered as an exception in the Montreal Protocoldesigned to fight global warming, even though they go «against their ultimate goals.»

«We are now paying attention to these emissions because of the successful use of the Montreal Protocol. The CFC emissions produced by much of their emissions are banned and have fallen to such low levels that emissions from minor sources are now under our radar«Luke Western, lead author of the study, explained in a statement from Bristol University.

The research underlines that the level of emissions detected «does not significantly threaten«the recovery of the ozone layer, but still»change to the weather«of the planet.

«Combined, these are emissions CO2 equivalents emitted in 2020 by a small developed country like Switzerland«, described Western, which quantifies the amount of gases released into the atmosphere around 1% of the greenhouse gas emissions of the United States.

CFCs, chemicals that destroy Earth’s protective ozone layerit was used to make hundreds of products such as aerosols, foams, and packaging materials, but it was banned in 2010.

The Montreal international treaty did not, however, eliminate the possibility of creating CFCs during the development of hydrofluorocarbons (HFC), a second generation of substances created to replace the first.

The study published in «Nature Geoscience» affects the emissions of CFC-13, CFC-11a, CFC-113A, CFC-114a and CFC-115 gases, chemicals with a half-life in the atmosphere between 52 and 640 years.
