I think that is the essence of the issue as we see it and why we think there are some drawbacks to having a one-size-fits-all, top-down-driven approach: that you're in danger of being insensitive to individual circumstances.
We know that departments have different circumstances. For example, Correctional Services Canada has a very old set of buildings to deal with. To expect them to meet the same energy efficiency standards or GHG emission targets as others would be unrealistic, given their building stock right now. Others may have a different configuration of buildings or fleets. That will all make a difference to what they can achieve in the short term rather than the long term.
So there is a danger in dictating the same for everyone, for sure.
