The idea of a revenue-neutral carbon tax is hardly new. My colleagues Clifford Cobb, Jonathan Rowe, and I wrote about this 20 years ago in an Atlantic cover story. What’s new is that in 2008, the right-of center government in British Columbia introduced such a plan, and sufficient time has now passed to weigh the results. Fossil fuel use in British Columbia has since fallen by 16 percent, as compared to a 3 percent increase in the rest of Canada, and its economy has outperformed the rest of the country. So the benefits of this approach are no longer theoretical.
