Japan plans climate change cut

Japan's next leader has promised a big cut in greenhouse gas emissions, saying he will aim for a 25% reduction by 2020 compared with 1990 levels.

Democratic Party leader Yukio Hatoyama is due to take over as prime minister on 16 September, after a resounding election victory in August.

His predecessor, Taro Aso, had pledged cuts of only 8%.

Mr Hatoyama said the plan was dependent on other nations agreeing targets at December's climate talks in Copenhagen.
