The Japanese government has increased its climate aid package to poor countries from $9.2 billion to $15 billion until 2012, the Kyodo news agency has said.
The aid will be provided on the condition that ''a fair and effective framework with the participation of all major emitters'' is established with an accord on their ambitious targets, the agency said.
The aid will come within the framework of the so-called "Hatoyama Initiative," voiced by Prime Minister Yukio Hatoyama during the September summit in New York.
Under the initiative, Tokyo pledged to cut its greenhouse gas emissions by 25% to the 1990 level and to offer financial support to the developing states, which have been the hardest hit by the consequences of the global climate change.
The package, which includes $11 billion in public money, with the rest coming from the private sector, is the largest climate aid so far. The European Union has earlier pledged to allocate $10.6 billion for the purpose.
Six nations, including the U.S., said they would allocate a total of $3.5 billion to protect rainforests earlier in the day.
