We take a systems-based approach to environmental protection.

We recognize that protecting our natural resources, enhancing biodiversity and supporting conservation are key to a sustainable environment, and we integrate these concepts into our business decision-making and daily operations.

In executing projects, we use leading construction practices and we are committed to identifying, mitigating and proactively managing any potential negative impacts to the environment. Enbridge has a long history of environmental stewardship, underpinned by adherence to established and evolving regulatory processes, as well as our own corporate policies and procedures. Spectra Energy brought a similar history and approach and our ongoing integration work, initiated in the first quarter of 2017, includes the review and harmonization of the two companies’ respective environmental management frameworks to ensure a consistent approach in planning, constructing and operating our vast network of energy delivery infrastructure.

4 performance objectives:

• Enhancing our approach to environmental stewardship and protecting sensitive ecosystems
• Responsibly managing our impacts on water and managing our water use
• Responsibly managing our hazardous, non-hazardous and electronic waste
• Investing in organizations that help us responsibly manage our impact on land and species
