1 Our target addresses Scope 1 methane emissions associated with our natural gas transmission and gas storage assets, expressed in tonnes of CH4 per Bcf. For planning purposes, target progress is measured under the operational control reporting boundary, relative to the 2019 baseline year intensity of 10.72 tonnes CH4/Bcf, which we recalculated to align with the structural and methodological changes noted for the 2020 through 2023 reporting periods.
2 Comparable EBITDA is a non-GAAP measure. See the forward-looking information and non-GAAP measures section in our Report on Sustainability.
3 Restoration refers to returning disturbed land to equivalent land capability. Restoration activities are multi-year efforts with end-of activity targets rather than annual targets. Restoration proceeds when site conditions allow, with ongoing engagement with landowners until activities are successfully completed.
4 Includes Tier 1 and Tier 2 Canadian Indigenous spend and U.S. Native American spend.
5 TC Energy defines high-energy serious injury and fatality (HSIF) as an incident involving a release of high energy (greater than 1,500 Joules of physical energy) without direct control, resulting in a life-threatening or life-altering injury.
6 Significant process safety incidents are defined by TC Energy as unplanned or uncontrolled releases of hazardous material that result in severe consequences. They are a subset of Tier 1 process safety incidents. In evaluating the significance of the incident, we consider the environmental, reputational, regulatory, and financial impacts to our company. Health and safety impacts are excluded to prevent duplication with the HSIF metric. While significant process safety incidents may have an environmental impact, not all process safety incidents will have an environmental impact. This is merely one factor considered when determining whether an incident is classified as 'significant'.
