Paris Climate Agreement Signed By How Many Countries
From 30 November to 11 December 2015, France hosted representatives from 196 countries at the end of the Un Climate Change Conference (UN), one of the largest and most ambitious global meetings ever held. The goal was nothing less than a binding and universal agreement to limit greenhouse gas emissions to levels that would prevent global temperatures from rising more than 2oC above the lower temperature levels set before the start of the industrial revolution. Indeed, research shows that the cost of climate activity far outweighs the cost of reducing carbon pollution. A recent study suggests that if the United States does not meet its climate targets in Paris, it could cost the economy up to $6 trillion in the coming decades. A lack of compliance with the NPNs currently foreseen in the agreement could reduce global GDP by more than 25% by the end of the century. Meanwhile, another study estimates that achieving – or even exceeding – the Paris targets by investing in infrastructure in clean energy and energy efficiency could have great benefits globally – about $19 trillion. At the 2011 UN Climate Change Conference, the Durban Platform (and the ad hoc working group on the Durban Platform for Enhanced Action) were created to negotiate a legal instrument to mitigate climate change from 2020. The resulting agreement is expected to be adopted in 2015.  The United States played an important role in organizing and negotiating the Paris Agreement and signed it in 2015.
As one of its signatories, the United States has committed to reducing emissions by 26-28% by 2025 from 1990 levels. However, in 2017, the federal government announced its intention to withdraw from the agreement after a new government took office, and on November 4, 2020, the United States became the only nation to withdraw. Developed countries, while not legally required to contribute to the mitigation and adaptation efforts of developing countries, are encouraged to provide financial assistance and are held accountable for the funding they provide or are mobilized. “A safer, safer, more prosperous and freer world.” In December 2015, President Barack Obama envisioned leaving today`s children when he announced that the United States, along with nearly 200 other countries, had committed to the Paris Climate Agreement, an ambitious global action plan to combat climate change. International climate negotiations are organized by the Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC). Adopted in 1992 at the Earth Summit on stabilizing greenhouse gas concentrations in the atmosphere, the UNFCCC came into force in 1994, while the 1992 Rio Declaration set out the basic principles of intergovernmental environmental negotiations (preventive approach, polluter-pay principle, common but differentiated responsibilities).
