Right.
Well, I'm referring to emissions of over 350 toxic substances that are reported by big business in Canada to the national pollutant release inventory. My understanding is that the United States is looking at a cap-and-trade system for carbon emissions which will effectively put a price on it similar to a carbon tax. Everyone in the world is moving toward the pricing of carbon. Canada is taking some steps of leadership. I think it's anomalous for us to say we're going to put a tax on one pollutant and ignore 350 other toxic substances that we're pumping out.
