Another important point of the agreement was the decision to limit greenhouse gas emissions from human activity to levels that, of course, can be absorbed by soil, trees and oceans. Climate experts said the agreement meant reaching for net zero emissions between 2050 and 2100. The UN climate science body has decided that net zero emissions must be reached by 2070 to avoid dangerous warming. The Paris Agreement called on developed countries to provide financial resources to help developing countries cope with climate change and adapt. As part of an audit mechanism, developed countries were also asked to disclose every two years the “indicative” amount they could raise over the next two years and information on the share that would come from sources of public funding. A Washington Post/ABC News opinion poll of American adults from June 2 to 4, 2017 found that 59 percent of Trump`s decision to withdraw the United States from the Paris Accord was rejected and only 28 percent supported it. When asked about the impact of the withdrawal on the U.S. economy, 42 percent said it would hurt the economy; 32% thought it would help the economy; And 20% thought it wouldn`t make any difference.   The poll showed a clear division between party lines: 67 percent of Republicans supported Trump`s decision, but only 22 percent of independents and 8 percent of Democrats supported them.  As part of its commitment to the Paris Agreement, the United States promised to reduce its emissions by 26% by 2025 from 2005 levels to 28%. The other impact would be the moral impact, because the withdrawal of the United States will have an impact on other diplomatic efforts. Many environmental experts have condemned this approach by the United States. They said that this expected withdrawal was a “historic mistake, that our grandchildren, with bewildered dismay, will remember how a world leader could be separated from reality and morality.
The United States has announced its intention to withdraw as soon as possible, on November 4, 2019. After a year, on November 4, 2020, the United States officially withdrew from the agreement, randomly the day after the 2020 U.S. presidential elections.  On the other hand, developing countries were “encouraged” to provide this information every two years on a voluntary basis. One of the key features of the Paris Agreement was the way in which the agreement reflected the principle of “common but differentiated responsibilities” (CBDR), which was invoked four times in the CBDR principle. While the EU has pledged to reduce itself by at least 40% from 1990 levels. From 1990 to 2005, U.S. emissions increased by 17%, so that the Paris commitments were only 9 to 11% compared to 1990 levels. The United States is very advantageous compared to former US President Bill Clinton: “The abandonment of the Treaty of Paris is a mistake. Climate change is real. We don`t owe our kids anymore.
