Canada's oil sands pollution significantly underestimated

A recent study reveals that air pollution from Canada’s oil sands is up to 64 times higher than industry reports, matching the total emissions from all human-caused sources in Canada.

Ruth Kamnitzer reports for Mongabay.


In short:

  • The study used aircraft sensors to measure a wider range of pollutants than industry methods.
  • Emissions include volatile organic compounds and particulates harmful to health.
  • Indigenous communities have long expressed concerns about health impacts from oil sands pollution.

Key quote:

"The magnitude of emissions observed from oil sands operations was surprising, compared both to their reported emissions and to the total from all anthropogenic sources across Canada."

— John Luggio and Drew Gentner, study authors

Why this matters:

The underestimation of emissions raises significant health concerns, particularly for nearby Indigenous communities. The oil sands, one of the largest industrial projects in the world, have been under scrutiny for their environmental impact for years. This new data suggests that the true extent of their pollution is much greater, posing increased risks to air quality and health in surrounding communities.
