"Studies have shown a 16 percent decrease in fossil fuel use since the tax was implemented and British Columbia’s emissions have decreased 3.5 times faster than in Canadian provinces that don’t have a carbon tax."
Now there is an eye opener!  You increase the cost of an item by imposing a tax and the consumption/purchase of it went down.  Never would've thought of that. The problem is the leap from B.C. or Oregon reducing carbon output by a small percentage having any, any, impact at all on the amount of carbon in the atmosphere.  A carbon tax certainly would change how certain commodities are consumed and the quality of life for many people, no doubt about that.  A lot more doubts whether such small "feel good" items will have any environmental impacts.
