Environmental groups, an Alberta First Nation, and landowners urge the Alberta Energy Regulator for a thorough environmental impact assessment of the oilsands industry's carbon capture project. The coalition, represented by Ecojustice, seeks a public hearing on Pathways Alliance's $16.5-billion plan to capture CO2 emissions from over 20 oilsands facilities and store them underground. Concerns include water use, pollution, and safety, prompting calls for a comprehensive evaluation.
