Adaptation issues were at the forefront of the paris agreement. Collective long-term adaptation objectives are included in the agreement and countries must be accountable for their adaptation measures, making adaptation a parallel element of the mitigation agreement.  Adaptation objectives focus on improving adaptive capacity, resilience and vulnerability limitation.  The agreement introduced more than just reducing emissions, but also the clean development mechanism for carbon trading. This meant that countries that did not meet the reduction targets could « buy » the right to additional emissions from households in less polluting countries. They could also be offset by measures to combat climate change in developing countries. President Trump is pulling us out of the Paris climate agreement. In addition, countries are working to reach « the global peak in greenhouse gas emissions » as soon as possible. The agreement has been described as an incentive and engine for the sale of fossil fuels.   The Paris Agreement has a bottom-up structure, unlike most international environmental treaties that are « top down, » characterized by internationally defined standards and objectives and must be implemented by states.
 Unlike its predecessor, the Kyoto Protocol, which sets legal commitment targets, the Paris Agreement, which focuses on consensual training, allows for voluntary and national objectives.  Specific climate targets are therefore politically promoted and not legally binding. Only the processes governing reporting and revision of these objectives are imposed by international law. This structure is particularly noteworthy for the United States – in the absence of legal mitigation or funding objectives, the agreement is seen as an « executive agreement, not a treaty. » Since the 1992 UNFCCC treaty was approved by the Senate, this new agreement does not require further legislation from Congress for it to enter into force.  Taking part in an election campaign promise, Trump – a climate denier who claimed climate change was a « hoax » committed 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.
