PWGSC's inventory totals just over seven million square metres, or probably 72 million square feet. Half is crown-owned and half is leased. Our investments for greenhouse gas reduction targets are crown-owned. That's where we spend our money.
I mentioned earlier that we sometimes invest in leases. That depends on the nature of the leases. Some leases are triple net—the crown pays all costs. If it's a long-term lease, 15 years or so, improving the heating system in the building would pay us a dividend, because we would pay less for heating. But that's the rare occasion.
What we're talking about for the most part in this presentation, far and away, is the crown-owned inventory. For us, for Public Works, that's about three and a half million square metres, or 37 million square feet.
