Noting that climate talks in Barcelona were not meant to resolve tough political issues on finance and emission reduction targets, UN climate chief Yvo de Boer said the negotiations before the Copenhagen summit should be used to consolidate areas of consensus.
"We have advanced significantly in the negotiations on adaptation, technology transfer, on capacity building, and from reducing emissions from deforestation, and Barcelona can be an important opportunity to cast that in language that can go forward to Copenhagen," said Boer, the Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC).
"This will not be a spectacular session but it will be an important one," he added.
The five-day meet in Barcelona till December 7 is the last in the series of talks on the climate issue among governments meeting this December in Danish capital.
192 countries will meet at the Climate Change Conference in December and are expected to hammer out a climate treaty to succeed the Kyoto Protocol since the first commitment period under this treaty ends in 2012.
"At Copenhagen, governments must give their clear answer on what they will do to avoid dangerous climate change and how they will do it," Boer said.
