The UNFCCC (UN Framework Convention on Climate Change) negotiation process had already revealed its complexity in 1997 at the COP3 when the Kyoto Protocol was finalized. Since then we have witnessed the failure of COP15 (2009 Copenhagen) in reaching a consensus on a global agreement with legally binding reduction goals for a greater number of countries involved in the Kyoto Protocol, which produced the 'Copenhagen Accord,' separate from the formal UNFCCC process. Since 2009, the process has become increasingly complex and reflects the critical issues in the economic system and global energy, making it difficult to reach a new global legally binding agreement by 2015, which is active by 2020 as evidenced by the results of COP17 (2011) in Durban. The speakers participating in the COP 18 in Doha (November 26 to December 7) will update the public on the prospects for effective action on climate change that emerge during the conference.
