"Countries that fail to help (tackle global warming) should be suspended from membership, just like those that breach human rights," states Clare Short, the former International Development Secretary, according to The Guardian.

"If the Commonwealth is serious about holding its members to account, then threatening the lives of millions of people in developing countries should lead to the suspension of Canada's membership immediately," states Saleemul Huq, a lead author for the Intergovernmental Panel on Climate Change.

Canada signed the Kyoto Protocol in 2000, pledging to reduce greenhouse gas emissions by six per cent from 1990 levels by the commitment period ending in 2012. By 2007, its emissions were 34 per cent above its reduction target.
