As to carbon targets, what I'm aware of, and I could be wrong, is that the carbon target is a global or high-level target. I think you have to take a high-level target down to the individual building. Canada is supposed to reduce so many millions of metric tonnes of carbon, and to a design team that's a difficult concept. So I am supportive of setting a target.
