YOKOHAMA — Japan's reasons for not committing to a medium-term target for cutting carbon emissions are "unfounded," the chairman of the Intergovernmental Panel on Climate Change told The Japan Times on Saturday.

Rajendra Pachauri, who heads a group of scientists who are researching the effects of global warming, said Japan should not fear the cost of restricting carbon gas emissions or the consequences that might it have on corporate Japan.

"Whenever there is challenge, the Japanese industry has been able to rise to the occasion," he said.
