3 January 2019: The Kigali Amendment to the Montreal Protocol on
Substances that Deplete the Ozone Layer entered into force on 1
January 2019, following ratification by 65 countries. The UN
Environment Programme (UNEP, or UN Environment) announced
the entry into force, and noted that it will help reduce the production
and consumption of hydrofluorocarbons (HFCs), potent greenhouse
gases (GHGs), and thus to avoid global warming by up to 0.4°C this
century.
The need for the Amendment emerged from the 1987 Montreal
Protocol process, which controls ozone-depleting substances. With
HFCs’ use as an alternative to ozone-depleting substances in cooling
equipment, their role in warming the atmosphere became a greater
concern. In 2016, the Parties to the Montreal Protocol adopted the
agreement on HFCs at the close of the 28th Meeting of the Parties
(MOP 28) in Kigali, Rwanda. Governments agreed that it would enter
into force on 1 January 2019, provided that at least 20 Parties to the
Montreal Protocol had ratified it. On 17 November 2017, Sweden and
Trinidad and Tobago deposited their instruments of ratification,
bringing the number of Parties above the required threshold.
The Kigali Amendment is a resolution
“we cannot afford to break.”
In a guest article published on the SDG Knowledge Hub on 1 January
2019, Ozone Secretariat Executive Secretary Tina Birmpili called the
Kigali Amendment a resolution “we cannot afford to break.” She
reported ratifications from 65 countries recorded by 21 December
2018, with more expected, and said Parties have put in place practical
arrangements for implementing the Amendment.
