Under U.S. law, U.S. participation in an international agreement may be denounced by a president acting on the executive branch or by an act of Congress, regardless of how the United States acceded to the agreement. The Paris agreement stipulates that a party cannot withdraw from the agreement within the first three years of its entry into force. The agreement commits all countries to reduce their emissions and cooperate to adapt to the effects of climate change and calls on countries to strengthen their commitments over time. The agreement provides developed countries with a means to assist developing countries in their mitigation and adaptation efforts, while establishing a framework for monitoring and reporting transparently on developing countries` climate goals. Niklas Hohne of the NewClimate Institute, one of the partner organizations behind Climate Action Tracker, said: “Five years later, it is clear that the Paris Agreement is advancing the fight against climate change. We are now seeing a wave of countries registering [to achieve zero emissions]. Can anyone really afford to miss this wave? The Paris Agreement has an “upward” structure unlike most international environmental treaties, which are “top down,” characterized by internationally defined standards and objectives that states must implement.  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.  The implementation of the agreement by all the Member States combined will be evaluated every five years, with the first evaluation in 2023. The result will be used as an input for new national contributions from Member States.  The inventory will not be national contributions/achievements, but a collective analysis of what has been achieved and what remains to be done. Funding is a major issue that remains unresolved before The Cop26. Developing countries, which have suffered from a problem they have caused little, have been included in the Paris agreement. Fabius said the commitment of financial aid The French government must assure the poorest countries that $100 billion a year in financial aid to poor countries will be needed to reduce their emissions and cope with the effects of the climate crisis. “Money, money, money,” Fabius said, was at the centre of the discussions. “If you don`t have that $100 billion [the talks are going to fail].” The government could send a strong signal at the start of the new year by declaring its commitment to carbon neutrality by 2050 and promising to formally submit a new NDC as soon as it is able to do so.
(In the meantime, to meet the technical requirements of the NDC agreement, it could provide a substitute or provisional NDC, such as reintroducing the Obama administration`s 2025 target. Ideally, it would then be able to provide an ambitious and credible NDC in time for COP 26 late for December 2021 in Glasgow. The warning signs of this decisive moment are good, according to Laurent Fabius. Biden`s election to the United States means that it will move closer to the EU and China if it insists that net zero emissions be fully implemented. “We will have the link of the planets that made the Paris agreement possible,” Fabius told the Guardian.
