Abstract: The United Nations climate change negotiation is one of the most important multilateral processes in the past 20 years, which has been the center of interest of the international society. The latest debate on legal and procedural issues triggered by Russia, Ukraine and Belarus in 2013 shows that the rules and procedures on decision making process have become one of the major challenges for current and the future negotiations. The analysis is based on the ultimate objective of the UN process as well as its core value. Three different issues have been explored including the mandate, the rules and the decision making approaches. The research concludes that transparency, party-driven and consensus will continue to be the primary principles and decision making rule for the UNFCCC in future.

Key words: UN climate change process, rules and procedures for decision making, consensus
