The Paris Agreement is the first legally binding universal global agreement on climate change adopted at the Paris Climate Change Conference (COP21) in December 2015. The contracting parties may, after three years of the agreement`s entry into force, withdraw from the agreement; However, they cannot express reservations about the agreement. In accordance with the Vienna Convention on Treaty Law, “ratification” defines the international act under which a country consents to membership in an international agreement. Ratification is proven by the filing of a ratification instrument with the custodian. This gives the contracting parties the time necessary to obtain approval of the agreement on the national territory and to adopt all the national legislation necessary to give effect to this agreement. The Kyoto Protocol, the international agreement that preceded the Paris agreement, was also “under” the UNFCCC, although its provisions were largely followed by those of the Paris Agreement. Currently, 197 countries – every nation on earth, the last signatory is war-torn Syria – have adopted the Paris Agreement. 179 of them have consolidated their climate proposals with official approval, including, for the time being, the United States. The only major emitters that have yet to formally accede to the agreement are Russia, Turkey and Iran. The agreement commits all countries to reduce their emissions and cooperate to adapt to the effects of climate change and calls on countries to strengthen their commitments over time.
The agreement provides developed countries with a means to assist developing countries in their mitigation and adaptation efforts, while establishing a framework for monitoring and reporting transparently on developing countries` climate goals. The Paris Agreement (the Paris Agreement)  is an agreement within the framework of the United Nations Framework Convention on Climate Change (UNFCCC) that deals with the reduction, adaptation and financing of greenhouse gas emissions and was signed in 2016. The language of the agreement was negotiated by representatives of 196 States Parties at the 21st UNFCCC Conference of parties held at Le Bourget, near Paris, France, and agreed on 12 December 2015.   Since February 2020, all 196 UNFCCC members have signed the agreement and 189 have left.  Of the seven countries that are not parties to the law, Iran and Turkey are the only major emitters. “membership,” the place where a country becomes a party to an international agreement already negotiated and signed by other countries. It has the same legal effect as ratification, acceptance and approval. Membership usually takes place after the agreement comes into force, but it can also take place in advance depending on the terms of the agreement. Specific results of increased attention to adjustment financing in Paris include the announcement by the G7 countries of $420 million for climate risk insurance and the launch of a Climate Risk and Early Warning Systems (CREWS) initiative.  In 2016, the Obama administration awarded a $500 million grant to the “Green Climate Fund” as “the first part of a $3 billion commitment made at the Paris climate talks.”    To date, the Green Climate Fund has received more than $10 billion in commitments.
