Thank you, Mr. Bigras.
It's a complex question, as you know.
Obviously, there are sectors of our economy that, for a variety of reasons, are actually below their levels of emissions in 1990, quite contrary to what Mr. McGuinty suggested earlier when saying businesses have been waiting. In fact, those businesses have taken action for a variety of reasons, and there are real emission reductions to point to since 1990. That was done in the absence of policy on the part of Canada and the provinces, and in the absence of a firm price for carbon. Those firms did things that made sense, because they were investing in new technology, they were upgrading, and they were improving their efficiency.
Now, there are other sectors in the economy that are part of this large final emitter system that have seen significant growth in their emissions, for reasons of expansion—all of which produce economic benefits for this country. So we have a wide range of factors to look at in terms of how to make a plan.
Going back to a base of 1990 may work for some industries and not for others. That's a decision the government will have to make. But we've said that we want to make sure it's a fair and equitable plan and that it actually provides incentives for companies to continue to make the investments in the new technologies, which, at the end of the day, are the only things that are going to produce real and sustainable reductions in emissions.
