If I may, I don't believe in silver bullets. I don't even believe in aluminum bullets.
What I do believe is that there's going to be a cost, and some pain, for everybody. That starts with consumers making the right choices and changing the way you design products and the way you do many things. I think it was Gord Lambert who testified before the committee that it may be helpful, it may solve their problems, to add $1 to the cost of a barrel of oil. But I would point out to you what other jurisdictions have done in trying to reform the tax system in a way that you have revenue neutrality, but you shift taxes to look after areas where you can incent a change in behaviour. They call it ecological tax reform. What, for example, the Europeans have done is gotten rid of manpower taxes in some areas and shifted that to other areas, while maintaining a neutrality in terms of their overall tax load.
My big fear, and I'm not a politician, is that if we just think of taxes and taxes, and taxes and levies, at some stage people are not going to change their behaviour, and they're just going to get fed up.
So I believe there are no silver bullets. You're going to have to make a lot of bullets and get a lot of tools in this tool kit and be able to make sure you get the right kinds of behaviour from different sectors and from the consumer.
