New Oil Sands Pipeline Plan Would Dramatically Increase Carbon Emissions
The Vancouver Sun reports that Kinder Morgan, operator of the Trans Mountain pipeline that transports oil from Alberta to the Port of Vancouver, hopes to increase the capacity of the proposed pipeline “twinning” project. Here, I’ve updated previous estimates of embedded carbon emissions in proposed pipeline to the British Columbia (BC) coast.
The annual flow of carbon through the proposed twinning project and the proposed Enbridge Northern Gateway project (presuming full operation) would dwarf greenhouse gas emissions from British Columbia, an issue presented here in the past. Carbon emissions embedded in the Northern Gateway project alone would be greater than current BC emissions, and close to twice the 2020 goal. With the proposed increase in capacity of the Kinder Morgan twinning project (shaded green), emissions embedded oil exports from the proposed pipelines would be more than twice the current emissions from within the province itself. Total oil exports from the BC coast would be equivalent to over 3.6 times the provincial emissions target for the year 2020.
As we also discussed before, the pipeline expansion would completely undermine not just B.C.’s emissions reduction policy, but the entire country’s emissions reduction policy.
The second graph shows the estimated gap (i.e. necessary reductions) between the most recent national emissions estimate (2010, 692 Mt) and the policy goal for 2020 (17% reduction, ~607 Mt). The emissions embedded in the proposed Northern Gateway pipeline (82.5 Mt) is alone almost as great as the Canadian 2020 emissions gap (85.3 Mt). Add in the original Kinder Morgan proposal, the recent proposed bump in capacity, and the emissions embedded in oil exports of the pipeline would be 1.6 times the national emissions gap.
Ay, here’s the rub. Carbon exports are not included in a country’s emissions budget. The very reasonable international greenhouse gas accounting system allocates emissions to the country where the carbon, not the country where the carbon is extracted from the ground. From a pure accounting standpoint, BC and Canada’s carbon emissions would be affected by the construction and operation of the pipelines, but not the amount of oil or bitumen flowing through pipes to tankers on the coast.
The point here is about the greater challenge. The climate does not care where the carbon is burned. Should Canada bear some responsibility for the climate implications of extracting and transporting the carbon? Are we hypocrites to promote local emissions policies and controls while dramatically increasing exports of carbon to the rest of the world?
