Argentina signed agreements with seven countries on reducing green-house gas emissions during a United Nations climate conference in Buenos Aires, Argentine authorities said Saturday.

The Argentine delegation signed the agreements Friday with representatives from Spain, Austria, Canada, France, Netherlands, Italy and Denmark.

The documents were signed under the Mechanism for Clean Development within the framework of the Kyoto Protocol, which will become effective in February 2005 and expire in 2012.

The 10th United Nations Conference on Climate Change, held on December 6-18 in Buenos Aires, drew 2,200 participants from 178 countries.
