"The big achievement from this G8 so far is that the U.S. has come forward and met us on the 2 degrees goal. This is in the final text," he told Reuters.

The European Union has previously adopted the goal, which it says will require deep cuts in greenhouse gas emissions.

Reinfeldt also said that G8 nations also put off any discussion of ways to finance a new U.N. treaty for fighting climate change until a G20 meeting in Pittsburgh in September.
