I'm going to disappoint you, Mr. Bigras. I do have favourites, but I'm not going to answer that question here today, because that's not what this bill is about. As I said, this is going to evolve over years and decades in terms of how we do this. We don't know all the answers today. Technologies will evolve. New regulatory mechanisms will evolve. Politics will change. Ministers will come and go. For us to be prescriptive at this stage, I think would be inappropriate.
I would like to restate what I said before, that it seems to me that they come under five categories, and I wouldn't want to take any of the tools out of our tool kit. So we have five took kits, if you will.
The first is that we need to somehow put some kind of significant price on greenhouse gas emissions. The polluter-pays principle is not only a fair principle, but it also drives innovation and technology and investment decisions.
The second one is that we are going to actually have to have a government that regulates and governs, so regulations will play a variety of roles.
Third, we're going to need public investments. I and my party believe in public investments.
Fourth, we're going to need private investment. The investor confidence and the predictability of regular plans will help people to be able to make plans for those significant sectoral investments.
The last one is personal lifestyle changes. I think most of us are starting to do that. We talk about it. It's a topic at cocktail parties. It's a topic over coffee. I'm proud to announce that I bought a new bicycle and parked my car. That's hard to do at my age, but I'm doing it because we all need to make changes.
Those are the five general areas in which I think we'll have to make changes. I have a longer list that I can share with you later. There are dozens of ideas, and many of them have yet to come forward.
