What I would say is that if we're looking at greenhouse gas emissions and climate change as a global issue, there are many things Canada can do to help the world. The export of our products to nations that use coal, for example, has a net benefit to global emissions. The resulting effect may be an increase in Canada's domestic emissions but a decrease in the global emissions.
If we're tackling climate change from a global perspective, then I'd suggest that this is something that we should look at, quite clearly.
