I'm going to interject since I only have about a minute left here.
On the question of pain or no pain, you've taken early action. Imagine the scenario if you hadn't acted in 1997 and right now were faced with this committee, saying it would be a Kyoto target timeline.
I want to bring this around to what other sectors might be facing here. What would your options look like right now, knowing what you've just come through over the last number of years? What would your options look like in that short-term timeframe and time window? What would they be? Would you feel some pain if you hadn't acted earlier?
