European Union leaders intend to receive clear position of U.S. government on climate issue at the meeting in Washington this week.
Swedish Prime Minister Fredrik Reinfeldt says the EU is looking for "a clear position" from Obama before the December U.N. climate summit. Sweden holds the rotating EU presidency.
Reinfeldt said Monday he hopes the U.S. will make a commitment to cut greenhouse emissions and help finance poorer countries' efforts to cope with global warming.
EU leaders pledged last week to pay their "fair share" into a global fund for developing nations but failed to agree on a figure.
The last round of U.N. climate change talks before the Copenhagen conference are being held this week in Barcelona, Spain.
