The U.N. environment summit on Saturday accepted Japan's proposal urging promotion of the ratification of the 1997 Kyoto Protocol to curb global warming.
"States that have ratified the Kyoto Protocol strongly urge states that have not already done so to ratify the Kyoto Protocol in a timely manner," says the action plan.
Government leaders intend to adopt the Plan of Implementation on the final day of talks for the 10-day U.N. World Summit on Sustainable Development in Johannesburg.
"The text is a result of having worked to gain agreement from the United States, which has withdrawn from the Kyoto Protocol, without embarrassing them," Japanese Environment Minister Hiroshi Oki said.
