That is correct. The environmental benefits are not the only reason we're working on it. The transportation sector produces between 40% and 50% of the emissions, and natural gas can help move that. We don't have the technology today to run an 18-wheeler or large trucks on batteries or do something better than that, and we think it's a great opportunity for natural gas.
As a comment on the competitiveness of it, I think you have to recognize that among all these different pieces--whether royalties, taxes, or whatever--the Canadian Mcf figure of gas that gets produced has to be competitive with the Mcf produced that day in the U.S.
The U.S. advantage is that it's closer to the burner tip, as we say; there's more of a market there. In North America we produce about 75 Bcf--billion cubic feet--per day. About 14 Bcf per day comes out of Canada, so our biggest market is really to sell into the United States. It's been an exporting revenue source for years in Canada, and I think it's important that we stay very competitive and analyze that.
