In November 2020, 194 states and the European Union signed the agreement. 187 states and the EU, which are the basis for about 79% of global greenhouse gas emissions, have ratified or acceded to the agreement, including China and India, the 1st and 3rd largest CO2 emissions among UNFCCC members.    As of November 2020, the United States, Iran and Turkey are the only countries that account for more than 1% of global emissions that are not parties. When the agreement garnered enough signatures to cross the threshold on October 5, 2016, US President Barack Obama said: “Even if we achieve every goal. We will only reach part of where we need to go. He also said that “this agreement will help delay or avoid some of the worst consequences of climate change. It will help other nations reduce their emissions over time and set bolder targets as technology advances, all under a strong transparency system that will allow each nation to assess the progress of all other nations. `  The amount of the NSNs set by each country defines the objectives of that country. However, the “contributions” themselves are not binding under international law, for lack of specificity, normative character or mandatory language necessary for the creation of binding norms.  In addition, there will be no mechanism to compel a country to set a target in its NPP by a set date, and no implementation if a target set out in a NSP is not met.
  There will be only one “Name and Shame” system or like János Pásztor, the UN. Under-Secretary-General for Climate Change, CBS News said, a “name and encouragement” plan.  Given that the agreement has no consequences if countries do not comply with their obligations, such a consensus is fragile. A stream of nations withdrawing from the agreement could trigger the withdrawal of other governments and lead to a total collapse of the agreement.  While the United States and Turkey are not part of the agreement, as they have not declared their intention to leave the 1992 UNFCCC, they will continue, as Annex 1 countries, to prepare national communications and an annual greenhouse gas inventory.  Adaptation issues received more attention during the formation of the Paris Agreement. Long-term collective adjustment targets are included in the agreement and countries are accountable for their adaptation measures, making adaptation a parallel element of the agreement with reduction.  Adjustment targets focus on improving adaptive capacity, increasing resilience and limiting vulnerability.  The implementation of the Agreement by all Member States is assessed every five years, with the first evaluation taking place in 2023.
The result will be used as a contribution to member States` new national contributions.  The inventory will not be one of the contributions/performance of each country, but of a collective analysis of what has been achieved and what remains to be done. That was in 1998, not after the agreement was signed. Both the EU and its Member States are individually responsible for ratifying the Paris Agreement. It has been reported that the EU and its 28 Member States are simultaneously depositing their instruments of ratification to ensure that neither the EU nor its Member States commit to obligations belonging exclusively to each other, and some feared a disagreement on each Member State`s share of the EU-wide reduction target. Just like the British vote to leave the EU, the Paris Pact could be delayed.  However, on 4 October 2016, the European Parliament approved the ratification of the Paris Agreement and the European Union deposited its instruments of ratification on 5 October 2016 with several Eu Member States.  Under the Paris Agreement, each country must define, plan and report regularly on its contribution to the fight against global warming.  No mechanism obliges a country to set a specific emissions target by a set date, but each target should go beyond the targets set previously. . . .
