In addition to the Kyoto Protocol (and its amendment) and the Paris Agreement, the parties to the convention agreed to other commitments at the conferences of the parties to the UNFCCC. These include the Bali Action Plan (2007),  the Copenhagen Agreement (2009),  on the Cancun Agreements (2010),  and the Durban Platform for Enhanced Action (2012).  The question of the legal form of the agreement has not been resolved in Cancun and will be debated next year in the run-up to Durban. The ad hoc working group on long-term cooperation has been extended by one year and is expected to continue to discuss “legal options for an agreed outcome.” This means that the parties have yet to decide whether to adopt a legally binding agreement complementing the Kyoto Protocol, a comprehensive legally binding agreement for all countries that would replace the Kyoto Protocol, or another option in which the parties cooperate through COP decisions rather than a new treaty. (Jacob Werksman, director of institutions and governance at WRI, will soon have a position in the legal form.) Delegates from Cancun raised several important issues, such as the status of the Kyoto Protocol and the central issue of equitable burden allocation. These will be problematic in the future. However, the progress of the Cancun meeting on a wide range of issues forms the basis of a future agreement. Although the legal form of such an agreement remains uncertain, the Cancun agreements can assure governments that there is still a use for broad international debate within the framework of the UNFCCC and help focus preparations for the 2011 conference in South Africa. A long-term common vision of the Cancun Agreement aims to limit global warming below 2 degrees Celsius above pre-industrial levels. It also recognises the need to strengthen this target on the basis of scientific progress and to consider a target of 1.5oC at a later date. The common vision of the Cancun agreement is not about an explicit long-term goal of reducing greenhouse gas emissions, atmospheric GHG concentrations or a peak year.
