Unfortunately the emissions are not ranked by who emits the most. So I took it upon myself to do so, with some pretty big technical support from Rob Schmidt. The numbers are as follows:
[Edited to add] Joel Wood asked how these break down by industry. Environment Canada has the following:
Facilities in Alberta accounted for the largest share of reported emissions, with approximately 47% of the total, followed by Ontario with 21%. Next were Saskatchewan and Quebec, which accounted for 9% and 8% of reported emissions respectively...
When completing a report for the GHGRP, a reporter is required to identify the main activities occurring at its facility using the North American Industry Classification System (NAICS).4 In 2010, three NAICS-defined industrial sectors accounted for the majority ofGHG emissions – Utilities, primarily those generating electricity from fossil fuel, representing 40%; Manufacturing, accounting for 30%; and Mining, Quarrying, and Oil and Gas Extraction, accounting for 26% (Figure 1). The Manufacturing sector includes, but is not limited to, facilities engaged in cement and lime manufacturing; pulp and paper mills; petroleum refineries; chemical manufacturing; and iron, steel, aluminium and base metals production facilities. Activities of reporting facilities within Mining, Quarrying, and Oil and Gas Extraction include: production of petroleum and natural gas; oil sands mining, bitumen production and upgrading; and mining of coal, iron ore, other metals, potash and diamonds.
Note that these figures are only for the facilities that reported, not GHG emissions as a whole. The facility reports make up only 35% of all GHG emissions in Canada.
