The Newfoundland and Labrador government has approved hikes in greenhouse gas emissions at a nickel mine in northern Labrador and the Cenovus-owned White Rose oilfield off the coast of St. John’s.

Cenovus estimates that its new West White Rose platform will increase emissions at the oilfield by about 21 per cent at peak operation, or an amount equivalent to about 100,000 metric tonnes of carbon dioxide, according to documents obtained through access to information legislation by The Canadian Press.

That’s roughly the same as the emissions from more than 23,300 vehicles driven for one year, according to the United States Environmental Protection Agency.
