To contribute to the goals of the agreement, countries presented comprehensive national climate change plans (national fixed contributions, NDC). These are not yet sufficient to meet the agreed temperature targets, but the agreement points to the way forward for further measures. While the agreement has been welcomed by many, including French President Francois Hollande and UN Secretary-General Ban Ki-moon, criticism has also emerged. James Hansen, a former NASA scientist and climate change expert, expressed anger that most of the agreement is made up of „promises“ or goals, not firm commitments. He called the Paris talks a fraud with „nothing, only promises“ and believed that only a generalized tax on CO2 emissions, which is not part of the Paris agreement, would force CO2 emissions down fast enough to avoid the worst effects of global warming. The agreement entered into force on 4 November 2016, 30 days after ratification on 5 October 2016 by at least 55 countries representing at least 55% of global emissions. NDC contributions or „nationally determined contributions“ are contributions from each country and are an important part of the agreement. They have been developed by each country and decree specific emission reductions and other possible action plans to combat climate change. The United States has an ambitious goal with its NDC: „The United States intends to achieve a macroeconomic target, reduce its greenhouse gas emissions by 26-28% from 2005 levels by 2025 and do its best to reduce its emissions by 28%.

Taking part in an election campaign promise, Trump – a climate denier who has claimed that climate change is a „hoax“ perpetrated by China, announced in June 2017 his intention to withdraw the United States from the Paris Agreement. But despite the rose garden president`s statement that „we`re going out,“ it`s not that simple.

The withdrawal procedure requires that the agreement be in effect for three years before a country can formally announce its intention to withdraw. She`ll have to wait a year before she leaves the pact. This means that the United States could formally withdraw on November 4, 2020, the day after the presidential elections. Even a formal withdrawal would not necessarily be permanent, experts say. a future president could join us in a month. Under President Donald Trump`s administration, the United States has expressed its willingness to withdraw from the Paris agreement. Contrary to what Trump and his administration claim, this has not yet been formalized, and if that happens, it will take up to four years for the decision to be processed. This is an important aspect, but since the agreement is not legally binding, if the government does not want to comply with the Paris directives, they simply will not do so.
