Canada's image lies in tatters. It is now to climate what Japan is to whaling | George Monbiot

Until now I believed that the nation that has done most to sabotage a new climate change agreement was the United States. I was wrong. The real villain is Canada. Unless we can stop it, the harm done by Canada in December 2009 will outweigh a century of good works.

In 2006 the new Canadian government announced it was abandoning its targets to cut greenhouse gases under the Kyoto protocol. No other country that had ratified the treaty has done this. Canada was meant to have cut emissions by 6% between 1990 and 2012. Instead they have already risen by 26%.
