This statement reflects the weight of expectations for COP21. For many, the Paris Agreement was a success, reflecting a universal and explicit recognition among the nations of the world that climate change is a serious issue that requires urgent action. However, although the agreement has long awaited ambitions, there are no concrete measures. One way to get around this was to form a “high-ambition coalition,” announced three days before Friday`s deadline. Forged by small island states – a key figure was Tony de Brum of the Marshall Islands – and the EU was joined by many of the least developed countries, which amount to more than 100 nations. They could then negotiate together, with an agreed common interest. By the end, the United States, Canada and Australia had joined this coalition. He was hailed by EU Climate and Energy Commissioner Miguel Caéete as a key factor in the final agreement. Article 28 of the agreement allows the parties to terminate the contract following a notification of an appeal to the custodian. This notification can only take place three years after the agreement for the country comes into force. The payment is made one year after the transfer.
Alternatively, the agreement provides that the withdrawal of the UNFCCC, under which the Paris Agreement was adopted, also withdraws the state from the Paris Agreement. The terms of the UNFCCC`s exit are the same as those of the Paris Agreement. There is no provision in the agreement for non-compliance. 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. While the enhanced transparency framework is universal and the global inventory is carried out every five years, the framework must provide “integrated flexibility” to distinguish the capabilities of developed and developing countries. In this context, the Paris Agreement contains provisions to improve the capacity-building framework.  The agreement recognizes the different circumstances of some countries and notes, in particular, that the technical review of experts for each country takes into account the specific capacity of that country to report.  The agreement also develops a capacity-building initiative for transparency to help developing countries put in place the necessary institutions and procedures to comply with the transparency framework.
 Taking part in an election campaign promise, Trump – a climate denier who claimed climate change was a “hoax” committed by China – announced in June 2017 his intention to withdraw the United States from the Paris Agreement. But despite the rose garden president`s statement that “we`re going out,” it`s not that simple.
