The Paris Agreement, marked by the historic agreement once adopted, owes its success not only to the return of a framework favourable to climate change and sustainable development, but also to efforts to review the management of international climate negotiations. The Paris Agreement is supported by new initiatives that will all be adapted to the difficulties identified at the previous COP. This innovative approach is based on four elements: the adoption of a universal agreement. Define each state`s national contributions to reducing greenhouse gas emissions. Although the text of the agreement does not mention the content of these contributions, it obliges signatory states to establish a contribution plan, implement it and raise amounts every five years. Civil society`s participation in the negotiation process through the action programme adopted in November 2016, which brings together civil society initiatives from 180 countries. In 2015, members of civil society were appointed at a high level to facilitate civil society participation in the intergovernmental process. The financial commitment of developed countries to contribute up to $100 billion a year from 2020. This funding is expected to give priority to the states most affected by the effects of climate change The agreement officially entered into force on 4 November 2016, several days before COP22, and has been ratified by 169 countries (including the European Union 28), which account for 87.75% of emissions.
The agreement stated that it would only enter into force (and therefore fully effective) if 55 countries that produce at least 55% of global greenhouse gas emissions (according to a list drawn up in 2015)  ratify, accept, approve or adhere to the agreement.   On April 1, 2016, the United States and China, which together account for nearly 40% of global emissions, issued a joint statement confirming that the two countries would sign the Paris climate agreement.  175 contracting parties (174 states and the European Union) signed the agreement on the first day of its signing.   On the same day, more than 20 countries announced plans to join the accession as soon as possible in 2016. The ratification by the European Union has achieved a sufficient number of contracting parties to enter into force on 4 November 2016. The 197 “negotiators” committed to developing long-term strategies to develop low-greenhouse gas emissions. This is the first time that a universal agreement has been reached in the fight against climate change. 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. In addition, countries are working to reach “the global peak in greenhouse gas emissions” as soon as possible. The agreement has been described as an incentive and engine for the sale of fossil fuels.   On August 4, 2017, the Trump administration sent an official message to the United Nations that the United States is one of the United States.
