2009 United Nations Climate Change Conference

The 2009 United Nations Climate Change Conference, commonly known as the Copenhagen Summit, was held at the Bella Center in Copenhagen, Denmark, between 7 and 18 December. The conference included the 15th Conference of the Parties (COP 15) to the United Nations Framework Convention on Climate Change (UNFCCC) and the 5th Meeting of the Parties (MOP 5) to the Kyoto Protocol. According to the Bali Road Map, a framework for climate change mitigation beyond 2012 was to be agreed there.

The conference was preceded by the Climate Change: Global Risks, Challenges and Decisions scientific conference, which took place in March 2009 and was also held at the Bella Center. The negotiations began to take a new format when in May 2009 UN Secretary General Ban Ki-moon attended the World Business Summit on Climate Change in Copenhagen, organised by the Copenhagen Climate Council (COC), where he requested that COC councillors attend New York's Climate Week at the Summit on Climate Change on 22 September and engage with heads of government on the topic of the climate problem.

Connie Hedegaard was president of the conference until 16 December 2009, handing over the chair to Danish Prime Minister Lars Løkke Rasmussen in the final stretch of the conference, during negotiations between heads of state and government. On Friday 18 December, the final day of the conference, international media reported that the climate talks were "in disarray". Media also reported that in lieu of a summit collapse, solely a "weak political statement" was anticipated at the conclusion of the conference.

The Copenhagen Accord was drafted by the United States, China, India, Brazil and South Africa on 18 December, and judged a "meaningful agreement" by the United States government. It was "taken note of", but not "adopted", in a debate of all the participating countries the next day, and it was not passed unanimously. The document recognised that climate change is one of the greatest challenges of the present day and that actions should be taken to keep any temperature increases to below 2 °C. The document is not legally binding and does not contain any legally binding commitments for reducing CO₂ emissions. Many countries and non-governmental organisations were opposed to this agreement, but, throughout 2010, 138 countries had either formally signed on to agreement or signaled they would. Tony Tujan of the IBON Foundation suggests the perceived failure of Copenhagen may prove useful, if it allows people to unravel some of the underlying misconceptions and work towards a new, more holistic view of things. This could help gain the support of developing countries. Malta's Ambassador for Climate Change, Michael Zammit Cutajar, extends this to suggest "the shock has made people more open to dialogue"
