The level of NDCs set by each country sets the objectives of that country. However, the “contributions” themselves are not binding under international law because they do not have the specificity, normative character or mandatory language necessary for the creation of binding norms.  In addition, there will be no mechanism  to force a country to set a target in its NDC by a certain date and no application if a target set in an NDC is not met.   There will only be a “Name and Shame” system or, as János Pásztor, UN Under-Secretary-General for Climate Change, told cbs News (USA), a “Name and Encourage” plan.  Given that the agreement has no consequences if countries do not comply with their obligations, such a consensus is fragile. A net of nations withdrawing from the deal could trigger the withdrawal of more governments and lead to a total collapse of the deal.  The Paris Agreement is the world`s first comprehensive climate agreement.  It is rare that there is consensus among almost all nations on a single issue. But with the Paris Agreement, world leaders agreed that climate change is driven by human behavior, that it poses a threat to the environment and all of humanity, and that global action is needed to stop it. A clear framework has also been put in place for all countries to make emission reduction commitments and strengthen these measures over time. Here are some important reasons why the agreement is so important: The Paris Agreement is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC) that deals with the mitigation, adaptation and financing of greenhouse gas emissions and was signed in 2016.
The wording of the agreement was negotiated by representatives of 196 States Parties at the 21st Conference of the Parties to the UNFCCC at Le Bourget, near Paris, France, and adopted by consensus on 12 December 2015.   By February 2020, the 196 members of the UNFCCC had signed the agreement and 189 had become parties to the agreement.  Of the seven countries that are not parties to the law, the only major emitters are Iran and Turkey. In response to the climate challenge, the agreement recognises that states have common but different responsibilities, i.e. according to their respective capacities and different national circumstances. This agreement is a clear call from governments to be ready to implement the 2030 Agenda for Sustainable Development. Paragraph 1 of Article 21 of the Paris Agreement will enter into force 30 days after the date on which at least 55 countries, which account for 55 per cent of total global greenhouse gas emissions, have deposited their instruments of ratification, acceptance or approval with the Secretary-General of the United Nations. .
