Under the Paris Agreement, each country must define, plan and report regularly on its contribution to the fight against global warming.  There is no mechanism for a country to set an emission target for a specified date, but any target should go beyond the previous targets. The United States formally withdrew from the agreement the day after the 2020 presidential election, although President-elect Joe Biden said America would return to the agreement after his inauguration.  On October 5, 2016, when the agreement reached enough signatures to cross the threshold, U.S. President Barack Obama said, „Even if we achieve all the goals… we will only get to part of where we need to go. He also said that „this agreement will help delay or avoid some of the worst consequences of climate change.“ It will help other nations reduce their emissions over time and set bolder goals as technology progresses, all under a strong transparency system that will allow each nation to assess the progress of all other nations.    At the beginning of the Paris text, there is a language that developed countries must „make available to the contracting parties of developing countries“ to reduce their emissions and manage the effects of climate change with financial means tailored to those needs. The agreement reaffirms the collective commitment made previously by developed countries to provide $100 billion in grants, loans and investments in developing countries each year from public and private sources. 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.  Countries are also working to reach „the global peak in greenhouse gas emissions“ as soon as possible.
