A recent UN meeting saw a first step towards finding a successor to the Kyoto Protocol, with calls for the US, Australia and developing nations to take part after 2012 when the emissions reduction Protocol expires.

The meeting in Bonn begins consideration of what to do after 2012, but is already facing problems with nations such as India, China and Brazil pushing more developed nations to achieved promised cuts in their own emissions before trying to widen the accord. They also call for the provision of more aid and technology transfer. Developing nations also need to consider how to take part in future without stifling economic growth.
