Canada's first black carbon inventory, 2013 / : Premier inventaire de carbone noir du Canada

Emissions of second-largest contributor to black carbon emissions in Canada, black carbon have recently become a focus of attention for policy representing emissions of 12 kt, or slightly more than 26% of total makers, due to the emissions’ effects on the near-term warming emissions.
