LONDON (Reuters) - United Nations officials have agreed some proposals for guidelines to measure compliance with action against global warming under the Kyoto protocol on climate change, the U.N. in Bonn said on Monday. Mechanisms on emissions trading, clean development and joint implementation were at the centre of two weeks of talks in Bonn on the U.N. Climate Change Convention adopted under then Kyoto protocol in December 1997, the U.N. said. "Technical work on many of the methodologies and procedures needed for implementing the Convention and the Protocol is advancing well," said Michael Zammit Cutajar, the Convention‘s Executive Secretary. The issues were being debated by 1,500 participants from 300 government and intergovernmental organisations ahead of a fifth session in November of the parties to the Convention (COP-5) on how to implement measures against global warming. The talks, in Bonn, will take place from October 25 to November 2 and in the latter stages will be attended by ministers from around the world. Outstanding issues for the implementation of Kyoto must be finalised at COP-6 which will take place in the Hague in late 2000 or early 2001, the U.N. said.
