The UN climate conference should stick to the two tracks set by negotiators in Bali two years ago, the Alliance of Small Island States (AOSIS) said Wednesday.

"Our job here today is to ensure that the two tracks which we embarked upon in Bali -- one under the Kyoto Protocol and the other under the Convention -- are each brought to their separate but complementary conclusions," said Grenada Prime Minister Tillman Thomas on behalf of AOSIS at the high-level segment of the conference.

Thomas said the Annex 1 parties, which comprise developed countries, should reduce carbon emissions by more than 45 percent of 1990 levels by 2020.

This would ensure the world proceeded along a path that would restrict long-term temperature increases to well below 1.5 degrees Celsius above pre-industrial levels, he said.

Thomas also called for adequate technical and financial support for vulnerable countries, including small island countries and the least developed countries, as well as countries in Africa affected by drought and desertification.

The climate meeting was interrupted in the morning by protests from developing countries against documents proposed by host Denmark without consulting other parties. They claim the documents seek to evade responsibilities under the Kyoto Protocol.
