The G-77 group of countries and China on Wednesday blasted a Danish draft proposal for an agreement on climate change, saying it “threatens the success” of the ongoing Copenhagen summit.

The draft text, which was leaked, is a “serious and unfortunate development. It is a major violation that threatens the success of the Copenhagen negotiating process,” said Sudan’s Lumumba Stanislas Dia Ping, who heads the G-77 group.

The G-77 and China called on the Prime Minister of Denmark, Lars Løkke Rasmussen, not to make any such further attempts and also affirmed that the group would not walk out of Copenhagen and work towards an equitable outcome till the last minutes of the conference.

UN climate change chief Yvo de Boer said this draft was on a decision paper put forward by Danish Prime Minister.

“This was an informal paper ahead of the conference given to a number of people for the purposes of consultations. The only formal texts in the UN process are the ones tabled by the Chairs of this Copenhagen conference at the behest of the Parties,” he added.
