The thing with all the climate regulations that the left would like to implement is that all you do is outsource the pollution overseas. Make it too expensive to produce here and companies will set up shop in China or wherever instead, where there are few or simply no such climate regulations. If it's a matter of potential species extinction as alarmists like to claim then what we really should do is take over the second and third world by force, occupy all such nations under martial law, and put leftist climate standards into place globally. This would be the only way to preserve the atmosphere and hence the species. For some reason I don't see any lefties clamoring for this though.
