Mr. Chair, as was mentioned, the government does have a target. It is to reduce to 17% below 2005 levels by 2020. Environment Canada is, of course, the lead on the specific strategy itself.
A number of things have happened. The principal consideration is to harmonize with the U.S., because we have such a strong trading relationship. In synchronization with the U.S., light-duty and heavy-duty vehicle emissions have been looked at. They are in the process of looking at coal-fired electricity.
In Canada we have a very clean electricity system, with 75% of our electricity coming from non-GHG-emitting sources, principally hydro and nuclear. In the U.S. it is much more largely coal-based, so working with the U.S. to reduce that will have a bigger impact on GHGs than most other things.
The demand side is really where we can have an effect on GHG reduction. We just recently renewed our suite of energy efficiency programs. When we evaluated the old ones, we were looking at the tonnes of GHGs that the various initiatives were reducing; we're looking at the same for the new suite of programs. It's an important consideration, particularly when we look at the programs on the demand side.
