The challenge in aviation—except in the case of my colleagues here—is that we cannot use another fuel. The fuel alternative is like jet fuel. We cannot move to a hybrid or hydrogen system. So we are limited to using only liquid petroleum fuel. We are currently working with Transport Canada, and we have a voluntary memorandum of understanding with them to establish targets for fuel performance and reducing our emissions. We aren't the only ones working with Transport Canada. Canada's entire air industry is, including NAV CANADA and the other airlines. The department determined that a policy is needed. However, no department is a leader in this respect.
