Notes
1  Scope 1 and 2 emissions quantification prepared using The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (Revised Edition) and verified  by external third-party in accordance with the ISO 14064 Part 3: Greenhouse Gases: Specification
with Guidance for the Verification and Validation of Greenhouse Gas Statements (ISO, 2019).
2   Direct emissions (combustion, flaring, formation CO2, venting, and fugitive leaks from equipment) under operational control.
3   Total direct plus indirect emissions (from purchased power).
4   Total methane vented emissions excludes fugitive emissions.
5   Direct methane emissions (combustion, flaring, fugitive leaks from equipment, venting).
6   Freshwater withdrawals are within licensed withdrawal limits. We constantly seek recycled, saline, or alternative non-saline freshwater in preference to high quality non-saline water whenever possible.
7  Represents all water volumes shipped away from NVA operated facilties for disposal. This volume assumes 100% of shipped waste water is injected for disposal.
8  Spills outside of secondary containment reported to regulatory agencies as per jurisdictional requirements. Freshwater spills with no environmental impact are excluded.
9  Year-end full time and part-time employees count are included in this metric (Calgary and field employees combined). Contractor and temporary employees are not included in the employee count.
10  In 2022 NuVista updated exposure hours/$ estimates to align with Energy Safety Canada’s most recent published Health and Safety Metric Guideline.
11  2022 total, based on measured data, is less than 100, likely due to rounding error, measurement variability and water in temporary storage.
12 The water performance reporting methodology was revised in 2024 to improve accuracy and consistency in tracking water diversions and consumption. Key changes were the inclusion of previously excluded non-material volumes from small temporary diversion licences (TDLs) related to construction, pipeline testing, and drilling. Additionally, when water from multiple sources is consolidated in storage prior to use, reporting now prioritizes field-level transfer records rather than relying on reconciliations of volumes for AER reporting at licence close-out.

As a result of these changes, the record of total water use decreased by 12.4% and the fresh water use as a percentage of total water use declined from 97% to 96%. This reduction reflects improved data precision rather than a reduction in actual operational water use.
