You are right to raise the issue of leasing. It's an important issue, and green leasing is one of the things we are working very actively on.
For our long-term leases, we do require that buildings be LEED gold. For leases of greater than 10,000 square metres, as those leases are renewed or new leases come up, we require that a BOMA Go Green Plus assessment be done of the building so that we can evaluate our opportunity to lease that space. We ask that the landlord manage the space using a different BOMA program, the BOMA Go Green program, in new and existing buildings as well.
We think this issue is so important that we are actually working with a group of our colleagues in the provinces to develop a model green lease, if you will, some clauses that we could draw from to further green our leasing activities. It is a challenge. You can't make the same demands in every market across the country, and certainly our levers for making environmental improvements are more limited than they are when we are owners. But it is an area of significant attention that we are working on.
