The level of the NDC set by each country will determine the objectives of that country. However, the «contributions» themselves are not binding under international law because of the lack of specificity, normative nature or language necessary to establish binding standards.  In addition, there will be no mechanism to compel a country to set a target in its NDC on a specified date and not for an application if a defined target is not achieved in an NDC.   There will be only a «Name and Shame» system  or as UN Deputy Secretary General for Climate Change, J. Pésztor, CBS News (US), a «Name and Encouragement» plan.  Since the agreement has no consequences if countries do not live up to their commitments, such a consensus is fragile. A cattle of nations withdrawing from the agreement could trigger the withdrawal of other governments and lead to the total collapse of the agreement.  Former President Barack Obama planned to achieve this goal by reducing pollution from the supply sector, by far the largest emitter in the country. To do so, it adopted a comprehensive regulation called the Clean Power Plan, which promoted emissions from power plants and the diffusion of emission-free energy sources such as solar and wind power.
Trump has already dismantled that policy. After ratification, the agreement requires governments to submit their emission reduction plans. Ultimately, they must play their part in keeping global temperatures well below 2 degrees Celsius above the pre-industrial period and making «efforts» to keep them at 1.5 degrees Celsius. At the 2011 UN Climate Change Conference, the Durban Platform (and the ad hoc working group on the Durban Platform for Enhanced Action) were created to negotiate a legal instrument to mitigate climate change from 2020. The resulting agreement is expected to be adopted in 2015.  Since then, Turkey has argued that it is a developing country and that it has gained special circumstances allowing it to opt out of the provision of financial resources. But it still cannot access climate money, a condition that President Recep Tayyip Erdogan has said must change if Turkey wants to ratify the deal. Climate scientist and founder of Germany`s New Climate Institute, Niklas Huhne, said Turkey was «reseming» the list of countries that do not yet need to ratify the agreement. Despite Trump`s campaign promises, the White House is under intense pressure to stay in the Paris accord. Foreign Secretary Rex Tillerson, Energy Secretary Rick Perry, counselor and first daughter Ivanka Trump and her husband, adviser Jared Kushner, support staying in the agreement, but with some adjustments to the emissions target.
