The Paris Agreement was launched at the signing on April 22, 2016 (Earth Day) at a ceremony in New York.  After the agreement was ratified by several EU member states in October 2016, there were enough countries that had ratified the agreement to produce enough greenhouse gases in the world for the agreement to enter into force.  The agreement came into force on November 4, 2016.  17 Caparrs and Péreau  explore another path that could still be relevant in a world towards Paris. The authors envisage the gradual formation of a coalition, in which a high-level country, such as the EU, is gradually renewing a binding agreement, following a model similar to that of trade agreements. This alternative could co-exist with a comprehensive agreement on the basis of commitments and is therefore a path worth exploring. These agreements could be signed as a development of Article 6, but could also be part of an evolution of financial transfers to developing countries proposed in Article 9. These agreements must be negotiated between developed and developing countries. Moreover, as Gatti et al.  made clear in the biodiversity negotiations, any agreement that does not recognize the (growing) negotiating power of the South is seen as unfair and therefore doomed to failure. Offers must take into account the fact that both parties have bargaining power and essentially share the additional benefits.
Therefore, if an offer does not do so because it corresponds to a take-it or leave-it offer, if the applicant water the entire additional surplus, it is rejected (Gatti et al. show that the “incremental costs” contract under the Biological Diversity Agreement falls into this category). 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. 19 Analysis of unilateral measures also remains relevant to a post-Paris world, with some countries unilaterally deciding to be more ambitious than others (as the EU has done) or may in future consider unilaterally raising the level of their INDC ambitions (see Article 4 of the agreement).
