OSAKA (Kyodo) Kansai Electric Power Co. said Thursday it will buy 500,000 tons in carbon dioxide emission credits up until the end of 2012 from two hydropower stations in northern Vietnam.

The company will purchase 440,000 tons from the 82,000-kw Thai An station starting operation in August and 60,000 tons from the 11,400-kw Chieng Cong station going onstream later this month, it said.

Kansai Electric did not release the price of the deal.

The two projects have been approved for the Clean Development Mechanism in which industrial countries implement projects for cutting carbon dioxide emissions in developing countries and get credits to offset their emissions under the Kyoto Protocol.
