Communists and socialists were in Copenhagen marching against global warming after the talks were ended in chaos.
Talks remain deadlocked, with developed and developing nations remain at odds over who should cut emissions, how deep the cuts should be, and how much aid should go to poor countries.
Nine days of talks have produced no major breakthrough with some saying that delegates have spent too much time posturing and repeating positions rather than compromising, the Voice of America said on December 16.
The outcome of the historic climate change negotiations in Copenhagen hinges on the issues of emissions reductions and financing, United Nations Secretary-General Ban Ki-moon said on December 16, according to the UN News Service.
