Young said she hoped the United States would re-engage in the Paris agreement to minimize the worst climate risks facing countries like hers. “The fact that the country that has contributed the most to climate change is now formally outside the Paris Agreement and that it can remain so for at least the next four years is a terrible idea,” she said. The agreement is a massive redistribution of wealth from the United States to other countries. With a growth of 1%, renewable energy sources can meet part of our domestic demand, but with 3 or 4% growth that I expect, we need all forms of American energy available, or our country – (Applause) – will be seriously threatened by power cuts and power cuts, our businesses will often stop, and the American family will suffer the consequences in the form of lost jobs and a very low quality of life. “The United States should stay with the other 189 parties to the agreement and not go out alone.” Biden has not made any concrete commitments on the Paris agreement, other than that he would re-engage the United States in its goals and go “much further.” He said he would “lead efforts to increase each major country`s ambitions to achieve its national climate goals” and “prevent countries from cheating.” The pioneering agreement reached in 2015 aims to limit global warming to a level “well below” 2 degrees Celsius above pre-industrial temperatures. But in June 2017, U.S. President Donald Trump announced that the United States – the world`s second-largest emitter of greenhouse gases – would pull out of the agreement. The task becomes more difficult. Although high-emigration countries are increasingly interested in containing warming, experts warn that current climate and energy policies are not enough to keep the world below 2 degrees Celsius of warming. This year, greenhouse gas emissions have fallen significantly – due to lower travel activity and economic activity during the coronavirus pandemic – but this will do little to bring the world closer to its climate goal, experts warn. Since November 2020, 194 states and the European Union have signed the agreement.
188 countries and the EU, which account for about 79% of global greenhouse gas emissions, have ratified the agreement or have joined the agreement, including China and India, the countries with the first and third CO2 emissions among UNFCCC members.    All 197 UNFCCC members have signed or joined. Others say the U.S. withdrawal is due in part to the Obama administration`s inability to have the U.S. Senate ratify the Paris agreement. Other major economies, such as Japan and South Korea, last month promised to become carbon neutral by 2050, but did not explain in detail how they will achieve this. In total, more than 60 countries around the world – including all EU Member States except Poland – have pledged to achieve zero net emissions by the middle of the century. 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.
