President Obama was able to formally bring the United States into the international agreement through executive action, as he did not impose any new legal obligations on the country. The United States already has a number of tools in its books, according to legislation already passed by Congress, to reduce carbon pollution. The country formally acceded to the agreement in September 2016 after submitting its proposal for participation. The Paris Agreement can only enter into force when at least 55 countries representing at least 55% of global emissions have formally acceded to it. This happened on October 5, 2016 and the agreement entered into force 30 days later, on November 4, 2016. 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 Climate Change Conference took place on the 30th. November to December 12, 2015. This was the 21st meeting of the Conference of the Parties (COP 21) to the United Nations Framework Convention on Climate Change (UNFCCC) and the 11th meeting of the Meeting of the Parties to the Kyoto Protocol (CMP 11). Delegations from around 150 countries participated in negotiations on a new global and legally binding climate protection agreement. The authors of the agreement set a withdrawal schedule that President Trump must follow – which prevents him from irreparably harming our climate. In the period following the Paris Climate Change Conference, the EU submitted its Intended Nationally Determined Contribution (INDC) to the Secretariat of the United Nations Framework Convention on Climate Change (UNFCCC). The EU`s INDC expresses the EU`s commitment in the negotiation process for a new legally binding climate agreement with the aim of keeping global warming below 2°C. .
