Environmental Performance Monitoring and Assessment

Husky conducts analyses throughout a project's life cycle to verify that the impacts of its operations on the environment are minimized. As part of the environmental impact assessment for large projects, baseline studies are conducted prior to development activity to determine appropriate mitigation.

Husky meets or exceeds regulatory compliance requirements for monitoring and reporting, and strives to exceed compliance to effectively address risk. At Husky's major facilities, prescriptive programs are in place for monitoring and reporting of:

• Emissions to air and water
• Groundwater quality
• Soil quality within and in the vicinity of the facility.

Wildlife studies are part of the monitoring program at certain sites.

Regularly scheduled environmental audits are conducted at upstream, midstream and downstream facilities. Issues identified during the audits are recorded and addressed in an efficient and effective manner.

Husky has implemented protocols to improve environmental performance, including:

• An inactive sites management program to assess long-term inactive sites and establish priorities for remediation.
• An active environmental audit program at all Husky facilities.

Environmental Performance Reporting System

Husky's Environmental Performance Reporting System (EPRS) consolidates data from diverse sources, and calculates and reports environmental performance, including greenhouse gas (GHG) emissions, in a timely, accurate, repeatable and auditable way.

EPRS enables the Company to calculate environmental performances with improved timeliness, accuracy and increased frequency. As part of this process, an independent third party audits Husky's historical GHG emissions and calculation methodology so its emissions comply with domestic reporting and emission regulations.
