"We are committed to moving forward in that forum and call on all parties to actively and constructively participate in the negotiations on a comprehensive agreement at the UN Climate Conference in Indonesia in December 2007," the draft says.

That paragraph was excised from a previous draft in April.

Many other paragraphs stressing the urgency of the climate crisis remain deleted in the latest draft.

Diplomats says the cuts were made by a group of countries led by the United States but including Canada and Japan.

Negotiations to expand and extend Kyoto beyond 2012 are barely moving and diplomats are hoping that the G8 summit in the German resort of Heiligendamm from June 6-8 will agree on a declaration strong enough to revitalise the talks.

BALI MEETING

They say success at Heiligendamm -- which will include the leaders of major developing nations India, China, Mexico, Brazil and South Africa -- would raise hopes the Bali meeting could agree outline principles for new post-2012 talks.

Failure in Germany could delay the process even further and risk leaving a post-2012 vacuum given the time it is likely to take to negotiate and ratify any Kyoto replacement.

Reinstatement of the call to the Bali meeting is the only bright point in tense negotiations around the summit communique.

G8 president Germany wants the meeting to agree targets and timetables for cuts in global warming emissions and increases in energy efficiency in transport and power generation.

It wants agreement on action to limit the rise in average temperatures this century to two degrees Celsius, to cut global emissions by 50 percent below 1990 levels by 2050 and to raise energy efficiency in power and transport by 20 percent by 2020.

But in the latest draft text all references to these, as well as an entire section describing the importance of carbon trading and calling for its expansion, are in square brackets meaning there is still no agreement on them.

The United States, which rejected Kyoto in 2001 as economic suicide because it was not binding on boom economies China and India, is adamantly against any binding targets or timetables.

Washington, despite the fact that several states are starting up Kyoto-type carbon trading schemes, rejects carbon trading because of its implicit emission caps.

Developing countries argue that as most of the pollution in the atmosphere came from the developed nations, they should bear the brunt of the bill for tackling its causes and effects.
