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.  It will also allow the parties to gradually strengthen their contributions to the fight against climate change in order to achieve the long-term objectives of the agreement. 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. The funding is expected to give priority to states most affected by the effects of climate change Since Trump`s announcement, U.S. envoys have continued to participate – as expected – in UN climate negotiations to shore up the details of the agreement. Meanwhile, thousands of heads of state and government have intervened across the country to fill the void created by the lack of federal climate leadership, reflecting the will of the vast majority of Americans who support the Paris agreement. City and state officials, business leaders, universities and individuals included a base amount to participate in initiatives such as America`s Pledge, the United States Climate Alliance, We Are Still In and the American Cities Climate Challenge. Complementary and sometimes overlapping movements aim to deepen and accelerate efforts to combat climate change at the local, regional and national levels. Each of these efforts focuses on the willingness of the United States to work toward the goals of the Paris Agreement, despite Trump`s attempts to lead the country in the opposite direction. 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.
