The first challenge that we found was that we wanted departments to take a whole-of-department view on the most cost-effective and most impactful actions by first getting a good sense of the metrics, a good sense of where the emissions are per department, and then what actions they can take.
Usually, it's like three buckets of goods.
One is what spaces you don't need. As Mr. Radford said, if there's a floor or a building that you don't need, then you can consolidate or operate differently, and you don't need to heat and cool it. There's that component. The second component is how you make the buildings that you have as energy efficient as possible. The third is how you fuel-switch if there are still remaining carbon emissions and costing that out and getting a sense of what actions you can take.
As opposed to taking individual actions, what you can do is take a comprehensive approach to where your best emissions and impacts are. Departments are working on that in that kind of an approach, where they're looking at the whole of their portfolio. Mr. Radford talked about the work at PSPC.
The second thing, then, is that there are things like aging buildings and aging infrastructure. That's where we're looking at it over the next 30 years and saying, “Okay, what's our real property plan?” Then, how do you integrate that analysis into the real property plan so that when you do a retrofit you're thinking of these things, as opposed to having to redo the retrofit a second time? It's really integrating it there, I think, generally.
The other thing is that different departments are at different places. Some of the larger departments have more expertise and some of the smaller departments have less expertise, and then it's about sharing best practices and expertise from expert departments that have a lot of knowledge, buildings and fleets, etc., with departments that are working in a different area or have a smaller footprint. We're also sharing practices with the provinces, for example, and other partners.
