I'll admit that this story had flown under my radar. I heard about the legislation previously, but I didn't realize it had actually passed and was being implemented.
I'd almost care if the tax was big enough to do anything. Less than a cent on a litre of fuel isn't going to faze anyone. It's not even substantial enough to be sufficiently distinct from white noise (according to my gut, at least at 'conventional levels of significance') and thus serve as a basis for research.
But it's a good idea, and a small step, even if it should be more directly applied to consumers, and not assessed to companies based on how much fuel they import, which is perhaps one of the most distortionary things I've ever heard of.
