Paris Agreement Signatories List
On June 1, 2017, U.S. President Donald Trump announced that the United States would withdraw from the agreement.  Under Article 28, the effective withdrawal date of the United States is the fastest possible date, given that the agreement entered into force in the United States on November 4, 2016. If it had decided to withdraw from the UNFCCC, it could be informed immediately (the UNFCCC came into force in 1994 for the United States) and come into force a year later. On August 4, 2017, the Trump administration officially announced to the United Nations that the United States intends to withdraw from the Paris Agreement as soon as it has a legal right to do so.  The formal declaration of resignation could only be submitted after three years of implementation of the agreement for the United States in 2019.   These rules of transparency and accountability are similar to those set out in other international agreements. Although the system does not include financial sanctions, the requirements are intended to easily monitor the progress of individual nations and promote a sense of overall group pressure, discouraging any towing of feet among countries that might consider it. International agreements are initially signed to indicate their intention to do so, but they only become binding through ratification.
It may be an act of Parliament or some other formal adoption. Processes vary from country to country. Former U.S. President Barack Obama used controversial executive powers to ratify the 2016 Paris Agreement. The United States, which has always ratified the UN`s 187 list, began withdrawing from the agreement in 2019 and will withdraw on November 4 of that year. President Donald Trump doubts that greenhouse gas emissions are causing dangerous levels of global warming. The language of the agreement was negotiated by representatives of 197 parties at the 21st UNFCCC Conference of the Parties in Paris and agreed on 12 December 2015.   The agreement was signed at UN Headquarters in New York from 22 April 2016 to 21 April 2017 by states and regional economic integration organisations parties to the UNFCCC (convention).  The agreement stated that it would only enter into force 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. The ratification by the European Union has achieved a sufficient number of contracting parties to enter into force on 4 November 2016. In 1992, President George H.W. Bush joined 107 other heads of state at the Rio Earth Summit in Brazil to adopt a series of environmental agreements, including the UNFCCC framework, which is still in force today. The international treaty aims to prevent dangerous human intervention in the planet`s climate systems in the long term. The pact does not set limits on greenhouse gas emissions from individual countries and does not contain enforcement mechanisms, but establishes a framework for international negotiations on future agreements or protocols to set binding emissions targets.
