With the hard cap, primarily the time involved in putting the legislation in place or the system in place would be a major con.
A pro is that, you know, the oil and gas industry has a history of being treated perhaps differently, more lightly, than the rest of the industry. I know they're complaining now that they're being singled out, but the fact is they've generally been given a lot of “get out of emissions reductions free” passes along the way.
Knowing that we will achieve a certain level of reduction from the industry when it is so important that we actually get this industry under control, which is behind us and missing a lot of Canada's targets to date, would be a significant advantage.
