I'll start, and then my colleague Doug Nevison, who's responsible for the climate change branch, may want to come in.
Environment Canada is responsible for supporting actions across the government, including many of our own, that add up to achieving the government's climate change commitments. That's probably the clearest way I can articulate that. We don't tell departments what to do; we support the government overall in putting in place the cumulative programs and policies that they need to achieve the objectives.
Doug may want to come in on that point.
