Emissions at four Alberta tar sands mines 64% higher than previously reported

Oilsands CO2 emissions may be far higher than companies report, scientists say

Carbon pollution from four major tar sands/oil sands mines in northern Alberta is 64% higher than their owners reported using the United Nations’ standard emissions measurement framework, according to a study released this morning in the journal Nature Communications.

“The researchers, mainly from Environment Canada, calculated emissions rates for four major oilsands surface mining operations using air samples collected in 2013 on 17 airplane flights over the area,” CBC reports. The study found gaps from 13 to 123% between reported and actual emissions at the four facilities, a finding that “could have profound consequences for government climate change strategies”.

As for the fossils that submitted the data, “they’re just doing exactly what they’ve been told to do,” said John Liggio, an aerosol chemist at Environment and Climate Change Canada. “They’re not doing anything on purpose.”

But that doesn’t make the research finding any less significant. Accurate numbers on carbon pollution “inform national and international climate policies,” the study states. “Such anthropogenic GHG emission data ultimately underpin carbon pricing and trading policies.”

“The bottom line is we still have more work to do in terms of really determining how much is being emitted,” Liggio told CBC.

The findings of this one study place Canada’s total greenhouse gas emissions about 2.3 higher than they were previously believed to be, CBC notes. “If research eventually shows that other oilsands sites are subject to similar underreporting issues, Canada’s overall greenhouse gas emissions could be as much as 6% more than thought—throwing a wrench into the calculations that underpin government emissions strategies.”

On CBC, Liggio explained the standard, “bottom-up” method by which fossils are required to report their production emissions is fraught with uncertainty, factoring in everything from the carbon intensity of the fuels they use to whether plant maintenance activities may have driven a temporary spike in emissions.

With their flyovers, Liggio and his colleagues took “a ‘top-down’ approach involving hundreds of air samples taken during more than 80 hours of flights over four major surface mining operations in northern Alberta: Syncrude Canada’s Mildred Lake facility, Suncor’s Millennium and North Steepbank site, Canadian Natural Resources Ltd.’s Horizon mine, and what was then Shell’s Albian Jackpine operation, now majority owned by Canadian Natural,” CBC explains.

“Left out of the study, notably, are emissions from all oilsands operations that use in-situ extraction, pumping steam into the ground to get the petroleum out. About 80% of oilsands reserves, and the majority of current production, require in-situ extraction,” which means “the overall amount of underreported greenhouse gas emissions could be significantly higher.”

Dear [            ]:

There’s no denying it — there are deliberate attempts to overturn regulations and policies that protect our environment, health and safety.  Therefore, regardless of the rejection of Phillips 66’s crude oil trains, we must remain educated about potential threats.  Click on the link below to read the latest MRWG newsletter, which includes …

► How Kern County followed in SLO County’s footsteps … saying “NO!” to crude oil trains.

► How the federal government used flawed data when canceling improved brakes for trains.

► How railroads have yet again missed the deadline for installing new safety technology.

► How Canada is expanding their production of dangerous tar sands and investing in crude oil trains.

► Why Phillips’ former claim of needing oil trains to gain “energy independence” was simply misleading.

► Plus — dozens of recent examples of serious railroad and oil industry safety problems.

Respectfully,
