From my perspective, getting the targets entrenched sets the level of ambition. You then have the opportunity to design programs from year to year, on a three-year rolling average, or for 10 years, as long as they are working.
Regarding the whole issue of impacts, part of the reason that a Stern report for Canada is not necessarily the best investment is that Stern did a global analysis. Now, obviously, it is not the micro-analysis of Canada's exact situation, but it does give a perspective for any country on the kinds of risks and the kinds of opportunities we have: the risks of inaction and the opportunity for action. It relates our programs in Canada very clearly to the cost of fossil fuels, which is going nowhere but up. We have opportunities for efficiency. We have the opportunity to save ourselves some pain and actually give ourselves some gain here. Not doing that is actually pushing us further behind, creating a cost of inaction. By not acting you will create costs for the public, for business, for government. These are very simple calculations to do, and they're based on that basic currency of fossil fuel costs. We're paying it, you're paying it, and it would be a real disservice to the Canadian public and to business throughout the economy to not actually get a grip on carbon.
