"Talks started on Monday to draw up a treaty to cut greenhouse gas emissions after 2012, when the existing Kyoto Protocol to fight climate change runs out. Experts nominated by more than 100 governments met in Bonn, Germany, on the first lap of negotiations likely to last two years or more.
But the first day revealed a fault line between governments. Some want a second phase of the Kyoto Protocol, with a similar recipe of national emissions targets and trading in pollution permits. But others want to tear up the Kyoto blueprint and start again, with a different system of targets - or perhaps no legally binding targets at all.
The two-day experts' meeting is aiming to set the agenda before negotiations begin in earnest when ministers meet in Montreal, Canada, in December 2005. Opening the meeting, the German environment minister Jurgen Trittin said the Kyoto target-and-trade system "has proved successful". He called for its continuation, with tougher emissions cuts of 15% to 30% - up to six times existing targets - to be met by industrialised nations by 2020.
But others said it would be easier to persuade Kyoto opt-outs like the US and Australia, and developing countries like China, India and Brazil, to accept targets if they were based on something other than crude cuts in national emissions."
