The Question
How could new and existing technologies be used to reduce the environmental footprint of oil sands development on air, water, and land?
Key Findings
Technological Prospects for Reducing the Environmental Footprint of Canadian Oil Sands reviews the environmental footprint of the three main bitumen processing activities (surface mining extraction, in situ extraction, and upgrading), and assessed a range of technologies with the most potential to reduce the environmental impacts on air, water, and land. The Panel then considered the impediments to the adoption of these technologies and estimated their potential to reduce the environmental footprint through to 2030.
Addressing the environmental impact of the oil sands is a long-term endeavour. Technologies implemented over the short- to medium-terms can reduce the footprint on a per barrel basis, however, none can bring absolute reductions. The greatest potential lies with emerging technologies that are longer term research and development prospects.
- A number of technologies (identified in the report) can help reduce the environmental footprint in all its dimensions in the short term if widely adopted; these are important but insufficient to achieve absolute reductions.
- An opportunity exists to accelerate the pace of technology development, creating a path to long-term and absolute reductions in the overall environmental footprint of the oil sands. This requires strong leadership, continued investment, and risk-taking by all.
- Opportunities to reduce GHG emissions lie primarily with in situ operations, a major source for emissions, which could rise by 300% by 2030 under 2014 production forecasts.
- There is no single “silver bullet” technology that can significantly reduce the volume of tailings and increase their consolidation for reclamation. However, a range of technologies used together may provide options for timely reclamation.
- Impediments to the accelerated adoption of the most promising technologies relate to the resources used, business decisions, and government policies.
