World leaders could put off major decisions on global warming for another six months time amid a warning from Gordon Brown that at the Copenhagen climate conference is threatened with “deadlock”.
Mr Miliband said bureaucratic wrangling was threatening to exhaust the time available to secure a deal at the Danish meeting.
"We have to find ways of unblocking this procedural wrangling because if we exhaust ourselves and run the clock down we will not get an agreement," he said, adding that he was frustrated at "talking about talks rather than talking."
Achim Steiner, the head of the UN Environment Programme, said that without a real deal, it could be better to defer big decisions until the next summit.
Mr Steiner said: “A meaningless deal in Copenhagen cannot be in anyone’s interests because it locks us into another decade of inadequate action and co-operation so if time runs out there is always the option of stopping the clock and reconvening to get it right. “But the risk is that that the momentum that is so characteristic of these 10 days in Copenhagen might be lost and then the world will struggle to take this further in the next six to 12 months.” Read more.
