The Canadian Press: Gore blames U.S. for failure at climate summit after blowing deal with China

MONTREAL — Former U.S. vice-president Al Gore says his country's lack of leadership on environmental change is partly to blame for the failure of last year's climate summit in Copenhagen.

Gore told a conference in Montreal Thursday the U.S. Senate's unwillingness to pass pre-summit legislation to reduce emissions botched a secret deal with China.

He says China had promised to push for a meaningful treaty in Copenhagen if Congress had passed a law curtailing emissions.
