PRIME Minister Gordon Brown and UN Secretary General Ban Ki-Moon last night raised hopes that a deal could be done to provide long-term finance for developing countries to fight global warming.

After a series of meetings at the UN climate talks in Copenhagen, Mr Brown said he thought there was more willingness to get an agreement on tackling global warming than public statements by countries at the crunch conference suggested.

And he said he thought a deal on long-term finance could be agreed to help developing countries cope with the impact of climate change and develop without massively increasing their pollution. The Prime Minister made the claims after discussions with Mr Ban to present proposals for breaking the deadlock in the talks – a blueprint which has not yet been made public.

Mr Ban had suggested that negotiations over the level of aid – a key sticking point in the talks – might have to wait, and appealed for “common sense, compromise and partnership”.

But last night he said sufficient financial and technological support was “key to bridging the gap between developed and developing countries”.

He added: “I can tell you at this time we would have some prospect of agreeing on long-term financial support.”

Mr Ban also said he hoped developed countries would come out with more ambitious mid-term targets for the cuts in emissions they would make by 2020.

Following the talks, Mr Brown said: “I think the Secretary General accepts now that a long-term finance deal, that he thought impossible, is something that can now be done. It’s important to recognise that every country on every continent has now got to make a contribution to this. We can move forward, but it demands a great deal of determination.”
