The highly anticipated conference marks an historic turning point on how the world confronts climate change, an issue with profound implications for the health and prosperity of all people.
Danish Prime Minister Lars Løkke Rasmussen announced that 110 heads of state and government will attend the conference at its conclusion.
The Prime Minister pointed to the fact that climate change knows no borders. "It does not discriminate, it affects us all," he said. "And we are here today because we are all committed to take action. That is our common point of departure - the magnitude of the challenge before us is to translate this political will into a strong political approach," he added.
The two-week meeting, the fifteenth Conference of the 193 Parties to the United Nations Framework Convention on Climate Change (UNFCCC) and the fifth meeting of the 189 Parties to the Kyoto Protocol, is the culmination of a process set in motion in Bali, where Parties to the UNFCCC agreed to conclude negotiations on a new global deal in Denmark in 2009.
As the conference kicked off, the UN Environment Programme (UNEP) released a report with Lord Nicholas Stern showing that the gap between countries' strongest proposed cuts and what is needed may be only a few billion tonnes of greenhouse gases.
UNEP Executive Director Achim Steiner arrived in Copenhagen on 5 December with the CO2-free Climate Express , a train from Brussels that brought together more than 400 activists, environmentalists and business leaders to discuss the challenges ahead to tackle climate change.
Other passengers on the train included James Leape, Director General of WWF and Jean-Pierre Loubinoux, Director General of the International Union of Railways. The Climate Express was welcomed upon arrival in Copenhagen by the new Minister for Climate Change and Energy, Lykke Friis, Søren Eriksen, CEO of the Danish Railways (DSB), and Kim Carstensen, Leader of WWF International's Global Climate Initiative.
Upon arrival in Copenhagen, Mr Steiner opened the UNEP Climate Maze, a giant labyrinth in the city centre made up of hundreds of cloth banners stamped and signed by Seal the Deal! campaign supporters. The accompanying photo exhibition, Hard Rain, is a stark exploration of the state of our planet and its people at this critical time.
