Yes, I have a really quick answer.
A World Bank report just came out which said that 60 countries are pursuing carbon pricing globally. Within Canada, some provinces are pursuing carbon pricing. There are elements of compliance flexibility in the current federal regulations that look a lot like some of the core elements of market-based instruments. Again, I refer to my previous comment that you need flexibility for people to make decisions to comply and at low cost. Again, you look globally and a lot is going on in all kinds of instrument areas.
