MOSCOW: Russia supports Canada's decision to pull out of the Kyoto Protocol, says its foreign ministry, reaffirming on Friday that Moscow will not take on new commitments.

Ministry spokesman Alexander Lukashevich told in Friday's briefing that the treaty does not cover all major polluters, and thus cannot help solve the climate crisis.

Canada on Monday pulled out of the agreement initially adopted in 1997 in Kyoto, Japan, to cut carbon emissions contributing to global warming.

Its move dealt a blow to the treaty, which has not been formally renounced by any other country.

''This is yet another example that the 1997 Kyoto Protocol has lost its effectiveness in the context of the social and economic situation of the 21st century,'' Lukashevich said, adding that the document does not ensure the participation of all key emitters.

The protocol requires some industrialized countries to slash emissions, but doesn't cover the world's largest polluters, China and the United States.

Canada, Japan and Russia said last year they will not accept new Kyoto commitments.
