COPENHAGEN (AP) — A Danish official says 65 world leaders so far will attend the Copenhagen climate summit in December and several more have responded positively to invitations.

The official says those coming include the heads of state or government of Australia, Brazil, France, Germany, Indonesia, Japan, Spain and the United Kingdom. He spoke on condition of anonymity because he is not an official spokesman.

Denmark last week sent out formal invitations to world leaders in 191 countries to attend the Dec. 7-18 U.N. climate summit in Copenhagen.

The conference aims to reach an accord on curbing emissions of greenhouse gases, which are blamed for global warming. The new treaty would replace the 1997 Kyoto Protocol.
