This is for Ms. Leung, but may apply to everyone.
We talked about the importance of the polluter-pay principle. Everyone supports it, but not necessarily how it should be implemented.
As I see it, this principle is really the way to go as far as the federal government's role in municipal waste management is concerned. Otherwise, I can't really see how else it could play an important role.
Ms. Leung, you talked about air and water pollution. You said we should be giving these problems greater consideration and perhaps even be attaching a price to greenhouse gas emissions.
Mr. Woodworth also said it was important to take greenhouse gases into consideration. Last week, witnesses told us that a price should be attached to carbon and that it would contribute to sustainable development.
I'll let you answer that.
