Oil Sands ESG: Progress vs. Liability

The oil sands industry in Canada is grappling with environmental, social, and governance (ESG) concerns. On one hand, some producers have made significant progress in reducing their greenhouse gas intensity by 36% since 2000 and recycling up to 98% of the water they use.

However, this progress does not necessarily translate to exclusion from ESG indices or large fund mandates. In fact, tailings ponds remain a major ESG liability for the industry. As of 2024, Alberta held approximately 1.505 billion cubic meters of fluid fine tailings, which require ongoing management.

The accumulation rate is accelerating, with an annual addition of 43.8 million cubic meters in 2024, up from 36.4 million cubic meters in 2023. This means that a decade of technological investment has not yet bent the accumulation curve downward.

The regulatory barrier also hinders progress. Alberta lacks a federal or provincial framework to authorize the release of treated mine water back into the environment, which means even treated water must stay stored on-site.
