The UN climate negotiations are heading for failure and need a major redesign if they are to succeed, scientists say.
The pledges that individual countries are offering ahead of the Paris climate summit in December are too entrenched in self interest instead of being focused on a common goal.
The researchers say the science of cooperation is being ignored.
Instead, they say the negotiations should focus on a common commitment on the global price of carbon.
This means countries would agree on a uniform charge for carbon pollution, a scheme that would encourage polluters to reduce their emissions.
The comments from researchers at the University of Cambridge, UK, University of Maryland, US, and University of Cologne, in Germany, are published in the journal Nature.
