Right now, I guess zero-emission vehicles would fall under the current greenhouse gas emission regulations, so we would argue that, with more stringent regulations, you end up effectively with a de facto zero-emission vehicle mandate, because the only way the vehicle manufacturers would be able to attain those emission standards under increasingly more stringent regulations would be to put more zero-emission vehicles on the road.
As far as zero-emission vehicle legislation is concerned in Canada, two provinces currently have what are called zero-emission vehicle mandates: British Columbia and Quebec. Each province requires manufacturers to meet a certain percentage of zero-emission vehicle sales as we move forward, and increasingly more stringent levels as we move forward. The federal government, as I mentioned, is currently looking at introducing a national zero-emission vehicle mandate.
