The Paris Agreement was launched at the signing on April 22, 2016 (Earth Day) at a ceremony in New York.  After the agreement was ratified by several EU member states in October 2016, there were enough countries that had ratified the agreement to produce enough greenhouse gases in the world for the agreement to enter into force.  The agreement came into force on November 4, 2016.  According to the United Nations Environment Programme (UNEP), temperatures are expected to rise by 3.2oC by the end of the 21st century, based solely on the current climate commitments of the Paris Agreement. To limit the increase in global temperature to 1.5 degrees Celsius, annual emissions must be below 25 Gigaton (Gt) by 2030. With the current commitments of November 2019, emissions by 2030 will be 56 Gt CO2e, twice the environmental target. To limit the increase in global temperature to 1.5 degrees Celsius, an annual reduction in emissions of 7.6% is needed between 2020 and 2030. The four main emitters (China, the United States, the EU-27 and India) have contributed more than 55% of total emissions over the past decade, excluding emissions due to land use changes such as deforestation. China`s emissions increased by 1.6% in 2018 to a peak of 13.7 Gt CO2 equivalent. U.S. emissions account for 13% of global emissions and emissions have increased by 2.5% in 2018.
EU emissions, which account for 8.5% of global emissions, have fallen by 1% per year over the past decade. Emissions fell by 1.3% in 2018. In 2018, 7% of India`s global emissions increased by 5.5%, but its per capita emissions are one of the lowest in the G20.  In the end, all parties recognized the need to “prevent, minimize and address losses and damages,” but in particular any mention of compensation or liability is excluded.  The Convention also takes up the Warsaw International Loss and Damage Mechanism, an institution that will attempt to answer questions about how to classify, address and co-responsible losses.  Nature studies indicate that from 2017 on none of the major industrialized countries implemented the strategies they had planned and did not meet the emission reduction targets they had promised, and even if this were the case, the sum of all accession commitments (from 2016) would not keep the global temperature increase “well below 2oC”.   The Paris Agreement  is an agreement under the United Nations Framework Convention on Climate Change (UNFCCC), which deals with the reduction, adaptation and financing of greenhouse gas emissions and was signed in 2016. The language of the agreement was negotiated by representatives of 196 States Parties at the 21st UNFCCC Conference of parties held at Le Bourget, near Paris, France, and agreed on 12 December 2015.
  Since February 2020, all 196 UNFCCC members have signed the agreement and 189 have left.  Of the seven countries that are not parties to the law, Iran and Turkey are the only major emitters. 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). Implementation of the agreement by all Member States will be evaluated every five years, with the first evaluation in 2023. The result will be used as an input for new national contributions from Member States.  The inventory will not be national contributions/achievements, but a collective analysis of what has been achieved and what remains to be done. The goal of the agreement is to reduce the global warming described in Article 2 and to improve the implementation of the UNFCCC by” on August 4, 2017, the Trump administration formally informed 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 not be submitted until after the agreement for the United States came into force on November 4, 2019 for a three-year date.   November 4 2
