Calgary, you're Number One!
Toronto has per capita carbon emissions of 9.5 tonnes. Vancouver comes in at 4.9 tonnes. But Calgary, your per capita carbon emissions are a staggering 17.1 tonnes.
Not only is Calgary the worst in Canada, it's the fifth worst city on the planet. Calgarians' emissions are even far worse than the inhabitants of smog-choked Mexico City.
Calgary suffers from urban sprawl, traffic congestion and an utter reliance on coal-fueled power plants.
