Unprecedented Recovery: Ozone Layer Heals Ahead of Schedule

Recent findings indicate significant reductions in hydrochlorofluorocarbons (HCFCs), harmful to both the ozone layer and climate. This success, stemming from the Montreal Protocol, shows that global efforts to phase out these substances are effective, with reductions exceeding earlier predictions.

A new study by an international team of researchers has revealed significant progress in the drive to reduce atmospheric levels of chemicals that destroy the Earth’s protective ozone layer, confirming the success of historic regulations limiting their production and use. Empa scientists contributed to this study with measurements from the high-alpine research station at Jungfraujoch.
