Examining the Revenue Neutrality of British Columbia’s Carbon Tax finds that the tax is no longer revenue neutral, and could actually result in almost $900 million in higher taxes over a six-year period. These findings are especially important given the federal government’s requirement on the provinces to adopt a carbon pricing system by 2018, and the fact that proponents often tout B.C.’s carbon tax as a model to follow, in part because of its alleged revenue neutrality.
