The United Nations Climate Change Conference, Copenhagen 2009, was hosted by the Government of Denmark. It was comprised of the following sessions:

• Fifteenth session of the Conference of the Parties (COP 15)
• Fifth session of the Conference of the Parties serving as the meeting of the Parties to the Kyoto Protocol (CMP 5)
• Thirty-first session of the Subsidiary Body for Implementation (SBI 31)
• Thirty-first session of the Subsidiary Body for Scientific and Technological Advice (SBSTA 31)
• Tenth session of the Ad Hoc Working Group on Further Commitments for Annex I Parties under the Kyoto Protocol (AWG-KP 10)
• Eighth session of the Ad Hoc Working Group on Long-term Cooperative Action under the Convention (AWG-LCA 8)

The Conference was an exceptional event that attracted unprecedented participation and resulted in:

• Attendance by 120 Heads of State and Government, raising climate discussions to a new level. More
• Record numbers of participants including 10,500 delegates, 13,500 observers, and coverage by more than 3,000 media representatives
  
• Intensive negotiations characterized by over 1,000 official, informal and group meetings among Parties. Observers discussed climate change in more than 400 meetings and media attended over 300 press conferences.
• A vibrant programme of over 200 side events.
  
• Over 220 exhibits from Parties, UN, IGOs and civil society
  
• A total of 23 decisions adopted by the COP and the CMP

Governments engaged at the highest political level, and the outcome of that engagement was reflected in the Copenhagen Accord. While much attention has focused on the Accord, the Conference in Copenhagen also made good progress in a number of areas including improvements to the clean development mechanism, amending Annex I to the Convention to add Malta, guidance on REDD+, and draft decisions on adaptation, technology, and capacity-building. However, the Bali Roadmap negotiations could not be concluded and negotiations will continue in 2010.
