Environmental Impacts of Shale Gas Extraction in Canada

Expert Panel finds monitoring, management, and oversight critical for responsible shale gas development in Canada

A new expert panel report, Environmental Impacts of Shale Gas Extraction in Canada, concludes that shale gas development must be supported by well-targeted science and management strategies to understand and mitigate potential impacts. The report, released today by the Council of Canadian Academies, addresses environmental and associated health impacts and offers insights regarding public engagement and trust.

"For Canada, regional context matters. A one-size-fits-all approach will not work to address the various potential environmental impacts that may exist across Canada's diverse regions," said Elizabeth Dowdeswell, President of the Council of Canadian Academies. "As such, communities and decision-makers will need to consider potential environmental impacts within their own contexts and decision-making processes."
The Panel's report sheds light on a variety of potential environmental impacts associated with well integrity; groundwater and surface water; greenhouse gas emissions; land impacts and seismic events; and human health. The report also addresses the importance baseline and ongoing monitoring, and the need for research and data-gathering.

Key findings
Although the technologies and techniques used in extracting shale gas are understood, more research and information is needed on the potential environmental impacts that could result from this process. In Canada, shale gas development has moved forward in British Columbia and Alberta while potential development is still being explored in Quebec, New Brunswick, and Nova Scotia. Unlike the United States, Canadian development has moved at a slower pace. This slower pace of development presents a unique opportunity for Canada to take the time to explore and determine the proper management practices to develop its shale gas resources responsibly.
For Canada, regional context matters. Environments, ecosystems, geographies, and geologies are not uniform across the country. Therefore, consideration of different potential regional impacts need to be closely considered when determining the suitability for shale gas development.
Overall, the Panel found that well-targeted science is required to ensure a better understanding of the environmental impacts of shale gas development. Currently, data about environmental impacts are neither sufficient nor conclusive.
The Panel's assessment focused on a number of environmental impacts. They include:
- Well Integrity
- Water (groundwater and surface)
- Greenhouse Gas Emissions
- Land Impacts and Seismic Events
- Human Health
- Monitoring and Research..."

Question
What is the state of knowledge of potential environmental impacts from the exploration, extraction, and development of Canada's shale gas resources, and what is the state of knowledge of associated mitigation options?
