World Ozone years and healing


Thanks to international cooperation the ozone layer is healing. It’s been 32 years since the global community agreed to the Montreal Protocol, which banned ozone depleting substances.

The Kigali amendment to the protocol, which entered into force in 2019, will continue to protect the ozone while phasing out HFCs. If the international community works together joins forces once again, the amendment has the potential to avoid a rise of up to 0.4 degrees Celsius by the end of the century.
