In the Olympics, judges award gold medals based on achievement, not ambition. We should adopt the same approach in evaluating Canada's newly revised target for reducing greenhouse gas (GHG) emissions — 40 to 45 per cent below 2005 levels by 2030.Some critics were quick to note that the United States and the European Union have announced even more aggressive targets.

How will they impact Canadians' lives?
