Notes:
- GHG emissions are reported for facilities that are under BC Hydro's operational control.
- Carbon dioxide (CO2) and carbon dioxide equivalent (CO2e) emissions are reported in metric kilotonnes. Methane (CH4) and nitrous oxide (N2O) emissions are reported in metric tonnes. Sulphur hexafluoride (SF6) emissions are reported in kilograms.
- GHG emissions are rounded to the nearest integer. Emissions reported as zero reflect this rounding. Totals may not add up due to rounding.
- GHG emissions associated with the corporate operations of wholly owned subsidiaries Powerex and Powertech are included.
- Where historical GHG emissions do not match previously reported values, emissions have been recalculated due to changes in inventory scope and/or improvements in data collection. This year, recalculations reflect:
- the integration of the BC Transmission Corporation with BC Hydro; and
- revisions to calculation methods for Stationary combustion (electricity and steam consumed by BC Hydro).
- BC Hydro purchased 30,000 tonnes of carbon offsets from the Pacific Carbon Trust to achieve carbon neutrality in its corporate operations (direct and indirect emissions from buildings, fleet vehicles and paper use) for calendar year 2010 as per the B.C. Carbon Neutral Government Regulation.
