I will try to answer your question and my colleagues can then add to it if need be.
My predecessor was here about two years ago with a number of colleagues from the partner departments. And you're right that the office of greening government operations, and Public Works more generally, does not have the ability to compel action on the part of departments. That said, there are a number of instruments that do bind departments. I mentioned one in the context of my statement--a Treasury Board directive relative to the executive fleet.
The policy on green procurement is an excellent example. It is a Treasury Board approved policy, and all departmental heads are responsible for implementing the policy within their departments. In addition to the requirement to implement what's in the policy, they also have the responsibility to report on their activities relative to that, through their departmental performance reports.
Guidance was provided by the Treasury Board Secretariat this year for how that's to be done. That first round of reports containing that information has yet to be completed. But for the current fiscal year there will be departmental reports relative to their obligations under that policy, to give you one example.
