When a country completes its necessary internal procedures, it can file its “ratification, acceptance or approval” in which it gives its consent to obtain the agreement. It is a formal document indicating that it has completed all necessary processes and is now in a position to accede to the agreement as a contracting party. How each country is on track to meet its obligations under the Paris Agreement can be constantly monitored online (via the Climate Action Tracker  and the climate clock). In the run-up to COP 21, many observers expected the Paris Agreement to enter into force after 2020, in line with the ADP`s mandate. However, Article 21 of the Paris Agreement does not contain a date when the agreement enters into force. Therefore, the speed with which countries are able to complete their national authorisation procedures depends on how quickly they are able to conclude their national authorisation procedures. It is likely that the Paris agreement will enter into force well before 2020. The Paris Agreement was adopted on 12 December 2015 at COP21 in Paris, France, by the Conference of the Parties (COP) of the United Nations Framework Convention on Climate Change (UNFCCC). The Vienna Convention on Treaty Law provides for the adoption of the formal act, the form and content of an agreement. In adopting the Paris Agreement, each of the contracting parties approved the text of the Paris Agreement. This does not mean that the parties to the UNFCCC will automatically become parties to the Paris Agreement.
The Kyoto Protocol, the international agreement that preceded the Paris agreement, was also “under” the UNFCCC, although its provisions were largely followed by those of the Paris Agreement. 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. Participating countries meet annually at a Conference of the Parties (COP) to assess their progress and continue discussions on how best to combat climate change. The Paris Agreement is the first truly comprehensive commitment to the fight against the climate crisis. In 2015, 195 countries and the European Union signed a single comprehensive agreement to keep global warming well below 2 degrees Celsius – and to do everything in its power to exceed 1.5 degrees Celsius.
