Climate Impact of Canada’s Oil Sands

A paper by researchers at the University of Alberta, Edmonton found that the impact of Canadian oil sands mining, and subsequent land restoration, on carbon release has been significantly underestimated. This is due to the mining process’s destruction of peatland – bogs, swamps, etc. that host partially decayed organic matter – which, when destroyed, releases high levels of carbon. From the paper’s abstract in the Proceedings of the National Academies of Science: “We quantified the wholesale transformation of the boreal landscape by open-pit oil sands mining in Alberta, Canada to evaluate its effect on carbon storage and sequestration.
