Regulatory and Environmental Risks: Evolving environmental regulations, stricter permitting processes, and increased scrutiny on greenhouse gas emissions could lead to project delays, increased compliance costs, or the denial of new permits, impacting Enbridge's growth and operational flexibility.

Pipeline Integrity and Safety Risks: The risk of pipeline ruptures, leaks, or explosions due to aging infrastructure, operational error, or external factors could result in significant environmental damage, safety hazards, regulatory fines, legal liabilities, and reputational harm.

Climate Change and Energy Transition Risks: A global shift towards cleaner energy sources and policies aimed at reducing carbon emissions could decrease long-term demand for fossil fuels, potentially leading to underutilization of existing infrastructure or the stranding of assets.
