Similarly, on the environmental side, Canadian carriers are very far ahead of their U.S. competition in terms of the need to improve fuel economy, which has the byproduct of improving GHGs. Whether that's because fuel was always more taxed here and more expensive here, I don't know, but the U.S. industry feels it's their God-given right to burn as much fuel as they want, when they want. We shouldn't lower our regulatory expectations to meet theirs.
