Japan, Britain and the United States will urge other G-8 member countries at the Group of Eight finance ministers meeting beginning Friday in Osaka to contribute to funds supporting developing country measures against global warming, the Finance Ministry said Thursday.

The Climate Investment Funds, to be established in early July, will be administered by the World Bank, and are expected to exceed 500 billion yen.

Japan plans to contribute about 130 billion yen over three years, while Britain plans to offer 800 million pounds (about 170 billion yen), and the United States 2 billion dollars (about 210 billion yen).

The three nations also plan to encourage non-G-8 member countries to contribute to the funds.

Australia has already indicated its intent to become involved, according to the ministry.

The funds, which will provide support to various projects until 2012, have been designed in an effort to incorporate the three nations’ differing approaches to the issue of helping developing countries tackle global warming.

The three nations judged such funds necessary to help developing countries reduce greenhouse gas emissions before the expiration of the Kyoto Protocol in 2012, an official at the ministry said.

The Climate Investment Funds comprise two distinct, dedicated initiatives: the Clean Technology Fund (CTF), which will help developing countries introduce clean energy technologies such as solar or wind power; and the Strategic Climate Fund (STF), which will develop safeguards against drought and flood in the developing world’s poorest nations.
