For precise numbers, I'll have to get back to you after checking with the experts. I believe about half of our total emissions come from what have been called the large final emitters, many of which are either resource industries, like oil and gas, or industries closely linked to resource industries, like coal-fired power, for example. And then about a quarter come from transportation and about a quarter from households and buildings.
On what the trends have been, I don't know. Again, we'd have to get you precise numbers and get back to you as quickly as we can.
