You also mentioned carbon pricing. What model do you think we need exactly? The Liberals talked about a carbon tax, and let's say that this isn't necessarily the right way to present the idea in marketing terms. We know that the Conservatives bashed all that.
To prevent this environmental dumping, we clearly have to do something. When you mention pricing, does that mean that we should develop a mechanism and show some imagination, as Mr. Feldman often reminds us? Should we show some imagination in finding an effective way of pricing the carbon of foreign countries, and do it as well by product? Do you have an idea of the form that might take?
