The Paris Agreement is a pioneering environmental agreement adopted by almost all nations in 2015 to combat climate change and its negative effects. The agreement aims to significantly reduce global greenhouse gas emissions in order to limit the increase in global temperature to 2 degrees Celsius above pre-industrial levels this century, while pursuing ways to limit the increase to 1.5 degrees. The agreement includes a commitment by all major emitting countries to reduce their climate pollution and strengthen these commitments over time. The compact provides a way for developed countries to assist developing countries in their efforts to combat climate change and adapt and provides a framework for transparency in monitoring, reporting and strengthening countries` individual and collective climate objectives. The contributions that each country should make to achieve the global goal are defined by that country and are called national contributions (NDCs).  Article 3 requires that they be “ambitious”, that they “represent progress over time” and that they be defined “with a view to achieving the objective of this Agreement”. Contributions are reported every five years and recorded by the UNFCCC secretariat.  Any other goal should be more ambitious than the previous one, called the “principle of progression”.  Countries can cooperate and pool their national contributions. The planned national contributions, promised at the 2015 Climate Change Conference, serve, unless otherwise specified, as the initial national contribution. intends to participate in joint EU efforts to reduce emissions across the region by 40% by 2030 compared to 1990 levels. The precise commitment it will make under this burden-sharing approach has yet to be decided; In the absence of an agreement, Iceland will submit a new INDC.
It is the INDC. 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.  At the conclusion of COP 21 (the 21st session of the Conference of the Parties to the Conference) on 12 December 2015, the final text of the Paris Agreement was adopted by consensus by the 195 States participating in the UNFCCC and by the European Union, in order to reduce emissions as part of the greenhouse gas reduction approach. In the 12-page agreement, members promised to reduce their carbon emissions “as quickly as possible” and to do their best to keep global warming “well below 2°C” [3.6°F].  Rarely is there a consensus among almost all nations on a single subject. . . .
