Well, to be a producer of credits, you need to be actively sequestering / somehow helping. So, arguably, the cost of credits will be massive at first (few people helping), and that should drive companies to spring up and plant trees, provide sequestration, ... whatever it is they do.

I don't think they ante up and go about business.

But, it really doesn't work unless everyone has to work with the carbon system, and that carbon trade system has been repeatedly shot down over and over.

But really, I have no idea if it's a good system at all, or if TFA describes that type of system.
