UNITED NATIONS, Oct. 28 (Xinhua) -- UN Secretary-General Ban Ki-moon said Wednesday that he is optimistic that world leaders will reach an ambitious agreement in December's climate change conference in Copenhagen, Denmark.
"On climate change, I'm still optimistic. This Copenhagen meeting will be an important milestone in our common efforts to address climate change issues," Ban told reporters at his monthly press conference at UN Headquarters.
There could be "a hallmark of success on climate change," if states can agree on four political elements -- ambitious mitigation targets; adaptation measures; the provision of financing and technology for poorer nations; and the creation of an equitable global governance structure, he noted.
"We are not lowering expectations" ahead of the Copenhagen meeting, the secretary-general stressed, noting that he has been working closely with Danish Prime Minister Lars Lokke Rasmussen, who is holding discussions with governments on the substance and form of an agreement that could emerge from the summit.
"There is a long way to go still," he said, with only five weeks to go before that meeting.
Post-Copenhagen, Ban emphasized to reporters that countries must endeavor to ensure that any agreements reached during the technical negotiations in Denmark can be built upon to become legally binding.
Negotiators are set to meet next week in Barcelona, Spain, for the last round of negotiations before the two-week Copenhagen gathering kicks off on December 7.
