Currently, 197 countries – every nation on earth, the last signatory is war-torn Syria – have adopted the Paris Agreement. 179 of them have consolidated their climate proposals with official approval, including, for the time being, the United States. The only major emitters that have yet to formally accede to the agreement are Russia, Turkey and Iran. Negotiators of the agreement stated that the INDCs presented at the time of the Paris conference were insufficient and found that “the estimates of aggregate greenhouse gas emissions in 2025 and 2030 resulting from the planned contributions at the national level are not covered by the least expensive scenarios of 2oC, but lead to a projected level of 55 gigatons in 2030.” and acknowledges that “much greater efforts to reduce emissions will be needed to keep the increase in the global average temperature to less than 2 degrees Celsius, by reducing emissions to 40 gigatonnes or 1.5 degrees Celsius.”  [Clarification needed] The Paris Agreement is an environmental agreement that was 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 global temperature increase to 2 degrees Celsius above pre-industrial levels this century, while continuing to pursue ways to limit the increase to 1.5 degrees. The agreement provides for the commitment of all major emitters to reduce their pollution from climate change and to strengthen these commitments over time. It provides developed countries with a means to assist developing countries in their mitigation and adaptation efforts and establishes a framework for monitoring, reporting and strengthening countries` individual and collective climate goals. The authors of the agreement have set a withdrawal period that President Trump must follow – which prevents him from irreparably harming our climate. On June 1, 2017, U.S. President Donald Trump announced that the United States would withdraw from the agreement.  Under Article 28, the effective withdrawal date of the United States is the fastest possible date, given that the agreement entered into force in the United States on November 4, 2016.
If it had decided to withdraw from the UNFCCC, it could be informed immediately (the UNFCCC came into force in 1994 for the United States) and come into force a year later. On August 4, 2017, the Trump administration officially announced to 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 only be submitted after three years of implementation of the agreement for the United States in 2019.   Unlike the Kyoto Protocol, which set legally binding emission reduction targets (and penalties only for non-compliance) for industrialized countries alone, the Paris Agreement requires all countries – rich, poor, developed and developing – to take their share and reduce their greenhouse gas emissions.
