I think I understand the question.
Certainly in the environmental assessment reports developed by review panels, they do question whatever international obligations or agreements are pertinent to the project, including issues that deal with air quality. Our review panels certainly do look at the cumulative environmental effect. They don't look at these projects in isolation; they look at the interaction of these potential effects coming from one project with other existing projects or future projects. It is a mandate of our review panels to do that.
