US issues warning on emissions targets

Attempts to begin negotiations on a new international climate change deal appeared to have hit difficulties today as the US said it did not want specific targets for global emission cuts in the “roadmap”.

An initial text of the document, which will lay out the route towards reaching an agreement in 2009, said the deal would work on the basis of scientific calls for 25% to 40% cuts on 1990 levels by 2020.
