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). Under the Paris Agreement, each country must define, plan and report regularly on its contribution to the fight against global warming.  There is no mechanism for a country to set an emission target for a specified date, but any target should go beyond the previous targets. The United States formally withdrew from the agreement the day after the 2020 presidential election, although President-elect Joe Biden said America would return to the agreement after his inauguration.  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.  A new global agreement on climate change was reached on 12 December. The agreement is a balanced outcome with an action plan to limit global warming to a level “significantly below” 2 degrees Celsius and to limit its efforts to 1.5 degrees Celsius.
As soon as the European Parliament gives the go-ahead, the closing decision will be formally adopted by the Council. The EU will then be able to ratify the agreement. The EU was the first major economy to present its emissions reduction target under the Paris Agreement. The EU`s current target is to reduce its CO2 emissions by 40% by 2030 compared to 1990 levels. However, the pressure to set a more ambitious level is intensifying. While the agreement has been welcomed by many, including French President Francois Hollande and UN Secretary-General Ban Ki-moon, criticism has also emerged. James Hansen, a former NASA scientist and climate change expert, expressed anger that most of the agreement is made up of “promises” or goals, not firm commitments.  He called the Paris talks a fraud with “nothing, only promises” and believed that only a generalized tax on CO2 emissions, which is not part of the Paris agreement, would force CO2 emissions down fast enough to avoid the worst effects of global warming.
 The EU and its member states are among the nearly 190 parties to the Paris Agreement. The EU formally ratified the agreement on 5 October 2016, allowing it to enter into force on 4 November 2016. In order for the agreement to enter into force, at least 55 countries representing at least 55% of global emissions had to file their ratification instruments.
