With regard to the rating systems, LEED in Canada has been developed and delivered by us. We're a non-profit organization. In the United States it's the U.S. Green Building Council. It was developed in the U.S. and then we adapted it in Canada to meet Canadian standards, climate, culture and so on, and we are delivering it in both official languages.
The best way to describe LEED is as a consensus standard. It's people from the industry, people like you, Stephen, other designers and engineers, and product manufacturers who come together. They are all members. They're stakeholders in the industry and every so many years LEED is updated and they contribute and say where the industry should go, where the thresholds should be, and what the targets should be.
So before a LEED rating tool comes onto the marketplace, there are sometimes years of discussion on what it should be, and it's piloted in the industry to make sure that it works. Then it is changed and piloted again, and sometimes changed again to make sure that the industry can actually use it, and that it is not so high a standard that nobody can use it, and it's not so low that it's meaningless.
It is that kind of consensus standard. LEED, in that regard, is actually unique because it has the stakeholders in the buy-in on a very large scale. That helps to continuously improve it and to make sure it still works, that it is relevant to the industry and continues to move forward.
