The international climate debate needs to embrace a "new way of thinking" to tackle the problem, UN Secretary General Ban Ki-moon has urged.

He called for both industrialised and developing nations to focus on limiting future global greenhouse gas emissions.

Mr Ban added that he would convene a climate summit to help reach consensus on a global climate action plan.

The idea of making developing nations enforce emissions caps has also faced opposition.

Recent attempts to reach a global agreement to replace the Kyoto Protocol, which expires in 2012, have ended in failure.

The global climate treaty requires industrialised nations to reduce their greenhouse gas emissions by 5.2% from 1990 levels, but the US and Australia have refused to ratify it.

"To build on the current momentum, I am going to convene a high-level UN General Assembly debate on 24 September."
"Business as usual is no longer an option - we must reach complete agreement," he told the audience in central London.
