The stratospheric ozone layer has undergone severe depletion as a result of anthropogenic ... Nitrous oxide behaves in a similar way to chlorofluorocarbons (CFCs): it is very stable in the lower ...

Attention focused initially on chemicals with higher ozone-depletion potentials including CFCs and halons. The phase-out schedule for HCFCs was more relaxed due to their lower ozone-depletion ...

Atmospheric halocarbons, including hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), and chlorofluorocarbons (CFCs), are a group of chemicals that have significant implications for ...

"Recognition of the adverse impact of chlorofluoro-carbons (CFCs) on stratospheric ozone has prompted ... HFC-134a does not contain chlorine and so has no ozone-depletion potential associated with the ...

Most ozone-depleting substances also contribute to global warming. By reining in these substances and protecting carbon sinks ...

The hole in the Antarctic ozone layer has been getting deeper in austral mid-spring over the last two decades, according to New Zealand researchers working with scientists from Otago University ...

Together, these patents strengthen PyroGenesis’ SPARC technology that specifically targets the destruction of end-of-life (EOL) refrigerants such as CFCs ... against ozone depletion and ...

The ozone layer plays a crucial role in protecting the planet. However, its effect and depletion are often a misunderstood ... Protocol to phase out ozone-depleting substances, including ...

Nov. 21, 2023 — Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years; researchers believe chlorofluorocarbons (CFCs ...
