I very much like your comments. I would actually add another idea into the mix.
This will probably not appear in the budget tomorrow, but one of the things we linked into our briefing on green taxes was the idea of an investment tax credit for environmental goods. If we're going to try to move to a lower carbon future, we can do things within the tax system to try to accelerate the adoption of greener technologies. There are a couple of paragraphs in our brief, if you're interested.
You would probably want an arm's-length group deciding which technologies would qualify, but as we head down the road, that's the kind of thing you could do, in addition to accelerated CCA, to try to encourage firms of all sizes to adopt the latest clean, greenest technologies.
