Pollution from Canada’s Oil Sands May Be Underreported

Canadian scientists have found that the standard way of tallying air and climate pollution from Alberta’s oil sands vastly understates pollution levels there — by as much as 4.5 times, according to a Canadian government study published Monday.

The study shows that air samples collected using aircraft may be a more accurate way to tally air and climate pollution from oil and gas production than using industry estimates.

Accurate accounting of the oil and gas industry’s pollution is critical for scientists to understand how fossil fuel production affects the climate and to find ways to cut the pollution to address air quality and climate change, said Allen Robinson, director of the EPA-funded Center for Air, Climate and Energy Solutions at Carnegie Mellon University, who is unaffiliated with the study.

Both the U.S. and Canadian governments rely on energy companies’ self-reported emissions estimates in order to count all the pollution from oil and gas operations.  Few actual pollution measurements are taken.

If official tallies underestimate the actual emissions, climate models will likewise underestimate the extent to which fossil fuel pollution is contributing to climate change, Robinson said.  The Canadian research shows that the energy industry has been underreporting its emissions and it highlights the challenges the industry faces in accurately estimating emissions from very complex equipment.
