And yet, three days before the conference, it seemed that all these efforts could not be completed. On the second Wednesday of the discussions, the French presented a second iteration of the central text, which reduced the number of brackets from more than 300 to less than 40. They hoped that this could be the end – and it needed to be the case for legal scrubbers and language experts to evaluate the text and ensure that it complies with international law and is correct in all languages. The Paris terrorist attacks raised questions about the continuation of the talks, but French President Francois Hollande insisted they do so and more than 150 heads of state landed in the French capital during a unity demonstration for the opening day. Barack Obama hailed the conference as an “act of defiance” in the face of terrorism. 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 required to keep the global average temperature rise to less than 2 degrees Celsius, by reducing emissions to 40 gigatonnes or 1.5 degrees Celsius.”  [Clarification needed] Prior to the Paris meeting, the United Nations instructed countries to submit plans detailing how they intend to reduce greenhouse gas emissions. These plans have been technically referred to as planned national contributions (INDC). As of December 10, 2015, 185 countries had introduced measures to limit or reduce their greenhouse gas emissions by 2025 or 2030. In 2014, the United States announced its intention to reduce its emissions by 26-28% from 2005 levels by 2025. To achieve this goal, the country`s Clean Power Plan should set limits for existing and projected emissions from power plants.
China, the country that emits the most greenhouse gases as a whole, has set a goal of reaching its carbon dioxide emissions “around 2030 and making the best efforts to reach an early peak.” The Chinese authorities have also sought to reduce carbon dioxide emissions per unit of gross domestic product (GDP) by 60-65% compared to 2005. The goal of the agreement is to reduce global warming described in Article 2, to “improve the implementation” of the UNFCCC This future could now be threatened, as President Donald Trump prepares to withdraw the United States from the agreement – a step he can legally take only after the next presidential election – as part of a larger effort to dismantle decades of the United States.
