Norwegian Prime Minister Jens Stoltenberg welcomes the Group of Eight (G8) summit's agreement to cut greenhouse gas emissions, but says it does not go far enough, reports said Friday.

Considering cutting emissions by 50 percent by 2050, without stating concrete goals, is disappointing, the prime minister was quoted by Norwegian Broadcasting as saying.

The G8 leaders reached an agreement Thursday on climate change during the group's annual summit, pledging to cut carbon emissions by 50 percent below the 1990 levels by 2050.

"They ought to have copied Norway's goals, and agreed to over-fulfill the Kyoto Protocol, and cut more than (what) they are committed to, by 2012," Stoltenberg told the broadcaster.

It is decisive that the United States makes concrete commitments, added the prime minister.
