Sweden says it will give $1.2 billion to help developing nations fight climate change.
Government spokeswoman Roberta Alenius says Prime Minister Fredrik Reinfeldt will announce Sweden's donation to a European Union program for a so-called "fast-start" financing fund on Thursday.
The total EU donation is expected to be proposed at the meeting in Brussels.
Sweden currently holds the rotating EU presidency and is heading talks with other members of the bloc about potential contributions.
Alenius said Wednesday that not all the 27 countries would be able to assist because some are experiencing serious financial problems.
