Wildly Underestimated Oilsands Emissions Latest Blow to Alberta’s Dubious Climate Claims

This blows out of the water any notion any idea that the Trudeau government is a ‘climate leader’ responding to the climate emergency in a robust fashion, protecting Canadians and the planet. Neoliberal governments protect corporations and investors’ profits before consideration of the public’s clear wish for robust action on climate change. Write to parliamentarians and voice your anger.

As disaster looms, petro province lets industry call the shots.

Whether or not the rest of the oil patch has as wretched a record of accuracy remains to be seen, but the missing 17 megatonnes thus far unearthed are enormous — equivalent to the entire carbon output of Toronto or Seattle.’ Photo by jasonwoodhead23, Creative Commons licensed.

Trust us. That has long been the message from the oil sector to the Alberta public, which seems to have little choice in the matter.

In a bizarre arrangement, the Alberta oil patch pays for its own oversight through the Alberta Energy Regulator — a regulatory body 100-per-cent funded by the fossil fuel sector. What could go wrong?

The latest boondoggle was revealed by an Environment Canada study published in the prestigious journal Nature Communications. It showed the methodology that energy companies have used for years to calculate carbon dioxide and methane emissions from oilsands surface mining operations underestimated contributions to global warming by a whopping 64 per cent.

This eye-popping number was the result of airborne sampling over four of the largest bitumen mines in 2013 to test the accuracy of the industry’s self-reporting methods. The company figures are based on “bottom-up” calculations using the measured amount of fuels consumed in their operations. The “top-down” sampling by Environment Canada was based on actual measurements of carbon dioxide levels collected over these projects.

…Similar airborne sampling by Carleton University researchers in 2017 assessed methane leaks from Alberta oil and gas operations and found that overall emissions were “likely at least 25 to 50 per cent greater than current government estimates.”

The oil industry enjoys a special deference from the mainstream media and regulators, so it is not surprising that the Environment Canada findings weren’t extrapolated to the rest of the bitumen industry. MORE
