"Nowhere else on Earth do fewer people steward more resources, yet Canada now stands dead last amongst the G8 Nations in protecting our shared home from the threat of dangerous climate change," said Keith Stewart, Director of WWF-Canada's Climate Change Campaign.

Overall, the Scorecard's message is that countries such as Germany, the UK and France have made commendable efforts, but action remains insufficient to set the world on a low carbon economy course. Further steps are needed to keep global temperatures below the danger threshold, defined as a two-degree rise of average temperatures when compared to pre-industrial times.

WWF says that to prevent climate change from reaching these danger levels, global emissions must peak and decline well before 2020 and be reduced by 80% by 2050.
