Due to their zero impact on ozone depletion, HFCs are currently used to replace hydrochlorofluorocarbons (HFCs) and chlorofluorocarbons (CFCs), but are potent greenhouse gases. With the addition of Kigali, the Montreal Protocol will be an even more powerful tool against global warming. The amendment will enter into force on 1 January 2019, provided that it has been ratified by at least twenty parties. The goal is to reduce HFC consumption by more than 80% by 2047. The effects of the change will prevent an increase in global temperature of up to 0.5°C by the end of the century. The main policy instrument to combat climate change to date, the Paris Agreement, aims to decarbonise the economies of signatory countries in the second half of the century and increase their resilience to the consequences of climate change. Mexico signed the agreement on September 14, 2016 ratified before the Mexican Senate. The commitments in the agreement include elements of mitigation and adaptation. The Kigali Amendment, ratified so far by 65 countries, builds on the historical heritage of the Montreal Protocol, adopted in 1987. The Protocol and its previous amendments, which require a phase-out of the production and consumption of ozone-depleting substances, have been universally ratified by 197 Contracting Parties. .
