Canada’s federal government insists the only way to reduce carbon emissions is by putting a price on them. But it will take a helluva price to coerce Canadians to reduce their driving enough to make a dent in transportation emissions, which are a huge contributor. That’s why the provinces are revolting against Ottawa and the 2019 federal election is shaping up as a referendum on carbon taxation. Gwyn Morgan has a radically better idea that would massively reduce emissions without punishing consumers: incent Canadians to convert their vehicles from gasoline and diesel to far cleaner-burning natural gas by making NGV fuel tax-free. Lower Taxes for Lower Emissions sure sounds like a better campaign slogan than Pay Up or Park Your Car.
