WELLINGTON, Nov. 6 (Xinhua) -- New Zealand's climate change ambassador Adrian Macey said on Friday that it is unlikely a new ratifiable climate change treaty will emerge out of talks in Copenhagen in December.

    The last round of negotiations were wrapping up in Barcelona, Spain, ahead of the meeting in the Danish capital of Copenhagen.

    Two years ago in Bali 190 nations pledged to agree to a successor to the Kyoto Protcol by the end of this year.

    New Zealand climate change ambassador Macey said though an agreement is on track - it might not be what everyone is expecting or wanting.

    "There is a sense of realism and lowering of expectation I think now pretty well universally shared, although not necessarily accepted by everybody," Radio New Zealand quoted him as saying.

    "We're not going to get a full ratifiable treaty outcome ... The big global comprehensive deal is not going to be finalized at Copenhagen - that's pretty clear," he added.

    Macey said it is likely there will be a strong political declaration and a set of decisions coming from the meetings in Copenhagen and it is not a question of despair.

    "All is not lost if you don't get that full, comprehensive deal at Copenhagen. The key thing is make sure what you get puts you on track to get there," said.

    The Barcelona meetings are due to finish on Friday evening local time.
