Day Five of the United Nations Climate Change Conference 2009

A first draft text presented to the Copenhagen Climate on Friday sets a minimum goal of halving world emissions by 2050.

Earlier in the week, emerging nations said that such a target implied additional cuts would be required from them. And China insisted that 2050 targets were not enough without strong emissions cuts from industrialized nations for the year 2020.

At the end of Day 5, the negotiators from 192 countries were handed over two sets of draft text for agreement to take the Copenhagen meet into the high-level ministerial round. The proposals they provided left developing country participants angry and wary.

OK, they're a long way short of constituting a final deal... but two draft texts, drawn up by conference chairmen and released to delegates today, demonstrate where compromises may have to be made if this fortnight is to result in the deal that so many governments say they want.
