Carbon rights a 'power game'

The climate change talks in Bangkok, Thailand last week was one of the latest international efforts to combat global warming.

Last month, the environment and energy ministers meeting of members of the G-20 intergovernmental forum concluded in Chiba, Japan.

As part of preparations for this year's G8 summit, the meeting reached consensus on a greenhouse gas reduction framework, but failed to agree on specifics. The result could affect Japan's efforts to become a leader in maintaining world climate order.
