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.  Paragraphs 6.4 to 6.7 define a mechanism “that contributes to the reduction of greenhouse gases and supports sustainable development.”  Although there is not yet a concrete name for the mechanism, many parties and observers have informally partnered around the name of the “sustainable development mechanism” or “SDM”.   The MDS is seen as the successor to the Clean Development Mechanism, a flexible mechanism under the Kyoto Protocol that would allow the parties to jointly monitor emissions reductions for their planned national contributions. The Sustainable Development Mechanism sets the framework for the future of the post-Kyoto sustainable development mechanism (2020). [must update] 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.
 The negotiators of the agreement stated that the INDCs presented at the time of the Paris conference were insufficient and found that “the estimates of aggregate greenhouse gas emissions in 2025 and 2030, resulting from planned contributions at the national level, do not fall into scenarios at 2oC at the lowest cost, but lead to a projected level of 55 gigatonnes in 2030.” and acknowledges that “much greater efforts to reduce emissions will be needed to keep the global average temperature increase to less than 2 degrees Celsius, by reducing emissions to 40 gigatonnes or 1.5 degrees Celsius.”  [Clarification needed] The Paris Agreement has an “upward” structure as opposed to most international environmental treaties that are “top down” , characterized by internationally defined standards and objectives that 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.
