That's certainly one part of the puzzle, but not the only part. As I would highlight and maybe others have highlighted before, we need something broader than command and control or directives to say do this. As Professor Elgie has mentioned, this is a flat line, whereas what you want is to provide growing incentives to do things.
It's important that the regulatory framework we use for projects encompasses an approach that truly recognizes both the benefits but also the cost, including the environmental cost of development of specific projects. From my perspective that would not be sufficient. We need something broader than that, that operates at a level where regulatory oversight is not necessarily a big factor in the activities.
