Kevin Carson, the writer of the fine Mutualist Blog, has responded in a brief post to one of my questions about green taxes. The discussion of green taxes is a really worthwhile one, especially as ICBC is considering switching to a system at least partially based on mileage. It could be a real improvement on the current flat-fee system, and help consolidate town cores, boost car pooling and transit ridership and reduce the amount of greenhouse gases in the air.
I'm sure some people will complain that it won't cut down on driving at all, but that's garbage. When cities switch to metered water supplies, there is always a decline in use. The situation is exactly parallel.
If nothing else, it would be fairer than the current system.
