Tokyo to propose cap-and-trade emissions plan

TOKYO (Reuters) - Tokyo aims to take a major step in meeting its pollution-reducing target by revising an emissions cutting bill.

The Tokyo Metropolitan Government will propose to the city assembly next month revising a bill to limit greenhouse gas emissions from big offices and factories in five years from April 2010, a city official said on Friday.

If passed it will enable the capital to become a pioneer in Japan by applying a mandatory cap-and-trade scheme of emissions on individual firms.

Japan's central government has been struggling to decide how to curb emissions beyond the current voluntary pledges by major industries, and whether to introduce a carbon trading scheme like the one in Europe.

"The new bill will make Tokyo an advanced environmentally-friendly city," said Satoshi Yamashita, director at Tokyo's environmental policy planning section.

"We understand that assembly members in general agree with a plan to cap emissions of major polluters and also with a trading scheme of emissions... We're hoping the bill will be passed in the next regular session starting in June," he said.

Even if it is not passed, the bill will continue to be discussed in the following sessions later this year, he said.

It is a necessary step for Tokyo to achieve its plan to cut greenhouse gas emissions by 25 percent by fiscal 2020/21 from 2000/01, Yamashita added.

The target is much tougher than the central government's commitment under the Kyoto Protocol, the U.N. led global climate pact, to cut emissions by 6 percent on average from 1990 levels by the 2008-2012 period.
