When some people here expected the end of the Kyoto protocol, the United Nations Summit on Climate Change continued on Wednesday the attack against any proposal aimed at ending it.

Such is the stage in which Australian Prime Minister Kevin Rudd performs, heading for a fierce rejection to his initiatives of reducing greenhouse gas emissions up to 25 percent for 2020, and a plan called "clean carbon" aimed at extracting the mineral and store it.

According to Group 77, the proposal "is not good enough," said Lumumba Di-Aping, who is the chief negotiator of that group formed by developing nations, and also China.

India also imputed to Rudd trying to impose a possible new accord to end with the Kyoto protocol, the only document that forces industrialized nations to reduce carbon emissions (CO2).

The truth is that the confrontation is much bigger between rich and poor nations in an unprecedented stage at a world conference attended by 46000 in the Danish capital.

New clashes were seen between local police and demonstrators in Copenhagen on Wednesday, with a total of over one hundred detained.

Drafts are circulating among the 194 delegations taking part at the summit, but none of them have been reconciled.
