Could I come back to a point that I think is the fundamental question? What do we do to create that transformation in the economy?
I would emphasize that 50% or more of the energy we use is used in Canadian cities and communities, our houses, our buildings, and the underlying infrastructure. The kinds of changes we're talking about by 2050, call it a 50%, 60%, or 80% reduction of greenhouse gases in absolute terms, won't work if we only do it in industry. We have to restructure our Canadian communities over the next 50 years, and that's got to be part of the puzzle.
