The Paris Climate Conference took place from 30 November to 12 December 2015. This was the 21st meeting of the Conference of the Parties (COP 21) to the United Nations Framework Convention on Climate Change (UNFCCC) and the 11th Meeting of the Parties to the Kyoto Protocol (CMP 11). Delegations from around 150 countries participated in the negotiations for a new global and legally binding agreement on climate change. The Paris Agreement is the world`s first comprehensive climate agreement.  Since Trump`s announcement, US envoys have continued to participate in UN climate negotiations, as planned, in order to consolidate the details of the agreement. Meanwhile, thousands of leaders across the country have stepped in to fill the void created by the lack of federal climate leadership, reflecting the will of the overwhelming majority of Americans who support the Paris Agreement. Among city and state officials, business leaders, universities, and individuals, there has been a wave of participation in initiatives such as America`s Pledge, the U.S. Climate Alliance, We Are Still In, and the American Cities Climate Challenge. Complementary and sometimes intersecting movements aim to deepen and accelerate efforts to combat climate change at local, regional and national levels.
Each of these efforts focuses on achieving the goals of the Paris Agreement, despite Trump`s attempts to steer the country in the opposite direction. Negotiators for the agreement said the INDCs presented at the time of the Paris conference were insufficient and noted «with concern that estimates of aggregate greenhouse gas emissions in 2025 and 2030, resulting from projected national contributions, did not fall under the least expensive 2°C scenarios, but would end at a projected level of 55 gigatonnes in 2030.» and recognizing that «much greater efforts will be needed to reduce emissions in order to keep the global average temperature rise to less than 2°C by reducing emissions to 40 gigatons or 1.5°C».  [Clarification required] President Obama was able to formally enter the United States into the international agreement through executive measures, as he did not impose new legal obligations on the country. The United States already has a number of instruments in its books, in line with laws already passed by Congress, to reduce carbon pollution. The country formally acceded to the agreement in September 2016, after presenting its proposal for participation. The Paris Agreement can only enter into force if at least 55 countries representing at least 55% of global emissions have formally acceded to it. This was done on October 5, 2016 and the agreement entered into force 30 days later on November 4, 2016. Article 28 of the Agreement allows the parties to terminate the contract after having sent a notification of resignation to the depositary.
Denunciation may take place for the country no earlier than three years after the entry into force of the Agreement. . . .
