EIA Briefing to the 37th Meeting of the Parties to the Montreal Protocol 3 – 7 November 2025 As the international community marks four decades of the Vienna Convention, the achievements made under the treaty and its Montreal Protocol stand as proof that, by following the science and prioritising the protection of human health and […]
Following revelations of unexpected CFC-11 emissions in 2018 and reports of record atmospheric HFC-23 concentrations and other unexpected emissions, legitimate questions have been raised as to whether the Montreal Protocol’s institutions and controls are fit for purpose, not only to sustain the phase-out of ozone depleting substances (ODS) but also to address the unique challenges of the hydrofluorocarbons (HFC) phase-down.
The legacy of the Montreal Protocol is one of delivering above and beyond its initial remit. UN Secretary-General António Guterres has described the Montreal Protocol as a “powerful symbol of hope”, calling on Parties to now go further. At MoP36, EIA calls on all Parties to embody the spirit of the Montreal Protocol once again and to demonstrate it truly is the world’s most successful environmental treaty.
EIA is urging significant investment in the ozone treaty, which can secure substantial additional greenhouse gas emission reductions in the near future. A new briefing “Meeting the Moment: Securing the Montreal Protocol’s Legacy in this Decisive Decade for Climate Action” analyses and provides recommendations on a variety of issues on the agenda for MOP35.
This briefing reviews phase out scenarios under discussion, accompanying measures, and interactions with the Kyoto Protocol and the Clean Development Mechanism.
