Well, my understanding, and perhaps the commissioner knows better, or the department can confirm this, is that what it's turned out to mean in practice is about how they are they meeting the greening-of-government stuff within their own departments, not how the actions of their departments are actually improving the sustainable development strategy.
You could read this a couple of ways, but I think if you read it in the more stringent way, and there is no reason not to, and perhaps somebody from the Department of the Environment can comment on this, there is already a bit of a carrot and a stick for civil servants to make sure they're being active on this file. It would seem, but I would defer to others, that maybe that hasn't been the case. But under the clear meaning of the act, it could be the case.
