We work all of the environmental and sustainable development strategies into our day-to-day operations, so we've adopted the BOMA go green plus program at Public Works and Government Services. We're doing the assessment of all of the buildings. Previous to that we had the sustainable development strategy, so many of the greening initiatives are already part of the way we deliver our services.
More recently we've adopted for our large-lease transactions the LEED gold standard for our leases and for our new buildings, so we don't really separate it as a separate funding pot any longer. There are initiatives that are put forward by the government. We try to access those dollars. Contaminated site cleanup, for example: we access that specific pot of money. But for the most part we've included it in our day-to-day planning.
