I'll take a stab at it. Canadian oil is ethical in treatment of workers and local environment but it is a very carbon intensive oil to produce. Getting usable oil out of the oil sands is an order of magnitude more carbon intensive than in Saudi Arabia, where they can basically drill a hole and move on. So, yes, Canada does a better job of regulating and capturing carbon but we also produce a lot more to begin with.
Please don't attack me about this. I understand there are other factors besides carbon intensity.
