I have to tell you that the only example I have to go by in how quickly technology can develop is based on my history. And this may not be an appropriate comparison, but it's certainly one that shows that when there is a regulatory sort of drop-dead deadline, the technology develops very quickly.
In 1990 some of you may recall that the pulp and paper industry was required by Environment Canada to get rid of dioxins out of its waste stream, dioxins being toxic in parts per trillion. This was one of the most hazardous chemicals known to man and it was a byproduct of the pulp and paper industry.
In 1990 the industry was told it had five years to get that dioxin out of its waste stream. The industry responded by saying, look, it was going to close mills, this was going to cost jobs—but in fact it did it in three years. It got dioxins out of the waste stream in three years' time because it had that looming deadline.
So when you ask me if they can transition, the technology is there. The question now is what is going to drive moving that more quickly, and I think it is a regulatory deadline. Why not five years? Five years could do it.
