World Ozone Day returns on 16 September and this year’s theme is fixing the ozone layer and reducing climate change.
The latest update from the scientific assessment panel to the Montreal Protocol confirmed that ozone layer recovery is on track and ozone levels are expected to return to 1980 levels by 2066 over the Antarctic.
By banning ozone-depleting substances and allowing the ozone layer to slowly recover, the Montreal Protocol is making a difference.
The Kigali Amendment to the Montreal Protocol aims to phase down the production and consumption of hydrofluorocarbons (HFCs).
By phasing down HFCs, the Kigali Amendment may result in avoidance of up to 0.5°C of warming by 2100. Implementing energy efficiency measures could potentially double this figure.
