The Paris Agreement was inaugurated at signing on 22 April 2016 (Earth Day) at a ceremony in New York.  Following the ratification of the agreement by several European Union states in October 2016, there have been enough countries that have ratified the agreement to produce enough greenhouse gases worldwide for it to enter into force.  The agreement entered into force on November 4, 2016.  The suspension of the first meeting would mean that the first meeting could take more than a year, or even several years if necessary, before the work is completed, in accordance with the timetable already agreed by the parties at COP21. There are already precedents for such procedures under the UNFCCC. COP6, which was suspended in 2000 due to the lack of agreement between the parties on key issues, was the most remarkable; in this case, the COP was suspended in The Hague in November and resumed in Bonn in July 2001 (“COP 6 bis”). There is also a more recent precedent within the EPA, which has held only two meetings, each composed of several parties over five years; the second session finally ended with COP21. “accession” means when a country becomes a party to an international agreement that has already been negotiated and signed by other countries. It has the same legal value as ratification, acceptance and approval. As a general rule, accession takes place after the entry into force of the agreement, but it can also be done in advance depending on the terms of the agreement. 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.  Although the agreement was welcomed by many people, including French President François Hollande and UN Secretary-General Ban Ki-moon, criticism also emerged. For example, James Hansen, a former NASA scientist and climate change expert, expressed anger that most of the deal is made up of “promises” or goals and not firm commitments.  He called the Paris talks a fraud without “no deeds, only promises” and believes that only an interterritorial tax on CO2 emissions, which is not part of the Paris Agreement, would reduce CO2 emissions fast enough to avoid the worst effects of global warming.  The amount of NDCs set by each country sets 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. .
