In contrast, the Kigali agreement divides states into four groups: The need for the amendment stems from the 1987 Montreal Protocol, which controls ozone-depleting substances. Because CFCs have been used as an alternative to ozone-depleting substances in refrigeration facilities, their role in global warming has become a major problem. In 2016, the parties to the Montreal Protocol adopted the CFC Convention concluding the 28th Meeting of the Parties (MOP 28) in Kigali, Rwanda. Governments have agreed that it will come into force on January 1, 2019, provided that at least 20 parties to the Montreal Protocol have ratified it. On 17 November 2017, Sweden and Trinidad and Tobago tabled their ratification instruments, exceeding the required threshold. Implementation of the agreement is expected to avoid up to 80 billion tonnes of CO2 equivalent emissions by 2050, which will contribute significantly to the Paris agreement`s goal of limiting global temperature rise to well below 2oC. Under the amendment, all countries will gradually reduce HFCs by more than 80% over the next 30 years and replace them with more environmentally friendly alternatives. A certain group of industrialized countries will begin to gradually become debt-ridted in 2019. Several developing countries will freeze consumption of CFCs in 2024, followed by other countries in 2028. The schedule for progressive planning is detailed here. The amendment also contains agreements on CFC destruction technologies, data reporting requirements and capacity-building provisions for developing countries. [UNEP press release] The amendment aims to massively reduce the use of CFCs, which have become substitutes for toxic fluids for ozone-depleting substances that expire under the Montreal Protocol. CFCs are climate-warming gases with high warming potential.
The parties to the amendment have taken practical steps to implement it, including agreements on CFC destruction technologies and new data reporting requirements and instruments. The amendment contains provisions for capacity building in developing countries, institutional strengthening and the development of national strategies to reduce CFCs and replace them with alternatives. The gradual wear and tear of CFCs under the Kigali amendment could also open a window to redevelop more energy-efficient refrigeration facilities, further increasing climate gains. The Kigali amendment to the Montreal Protocol is an international agreement to gradually reduce the consumption and production of hydrofluorocarbons (HFCs). The amendment was accepted at the 28th meeting of the parties to the Montreal Protocol in Kigali on October 15, 2016. In Decision XXVIII/1, they adopted an amendment to the protocol (the Kigali amendment).  Since its inception, the Climate and Clean Air Coalition has worked to reduce CFCs worldwide, a highly effective Cliamten agent and a short-lived climate agent. Coalition countries and partners worked together to reach an agreement for the adoption of the Kigali amendment to the Montreal Protocol and were among the first to ratify it.
This is a legally binding agreement between the signatories. January 3, 2019: The Kigali amendment to the Montreal Protocol on ozone-depleting substances came into force on January 1, 2019, after ratification by 65 countries. The United Nations Environment Programme (UNEP) announced its entry into force and said it would help reduce the production and consumption of hydrofluorocarbons (HFCs), greenhouse gases (GHGs) and thus prevent global warming by up to 0.4oC this century. The Kigali Amendment is a legally binding international agreement that aims to create rights and obligations in international law.
