Yes. I think the intention in putting a price on pollution is to incentivize a change in behaviour, but only if we have an option for people to migrate to. I think your comment about incentives being needed to encourage adoption rings very true for members of this committee.
I mean, if you look at zero-emission vehicles, a lot of people really only started buying them because, for example, here in British Columbia you got a combined $8,000 federal and provincial rebate for purchasing one. Of course, in the early days, the vehicles didn't have much range and they weren't as convenient, but now you're starting to get cars on the market that have a 400-kilometre or 500-kilometre range on a single charge. They can do all of the things that a gasoline car does, except maybe a trip right across the province. It takes some time, but eventually it will be like a snowball effect. It will build up enough pressure that it starts going on its own.
In terms of the new technologies that are coming out, what in your view seems to be the most promising? Are there a lot of companies involved in innovation in this field? Is there a lot of competition? Is there a lot of capital investment in trying to find out which one of these new technologies will actually become commercially viable?
