Mr. Chairman, if it would be helpful to the committee, I would add that the nature of the measures will vary across the operation. For example, on the renewal of the government fleet, I think there is relatively little we could do, even if we wanted to, to fudge the numbers. We would be reporting to the Treasury Board, as the commissioner has indicated, through internal audit and then through whatever external audits occur to provide the data about what the expenditures have been in fleet renewal and what the compliance has been with the standard across government for fuel efficiency, for example.
In other areas, I suspect we're going to have to provide considerable guidance from environment from other places about what are appropriate measures. In some cases, environmental measurement is a work in progress, and it would be more difficult. So I think there will in fact be a range of integrity of what the measures are, or objectivity in the measures, depending on what area we're talking about.
