Notes:

  • GHG emissions are reported for all facilities that are under BC Hydro's operational control.
  • Carbon dioxide (CO 2 ) and carbon dioxide equivalent (CO 2 e) emissions are reported in metric kilotonnes. Methane (CH 4 ) and nitrous oxide (N 2 O) emissions are reported in metric tonnes. Sulphur hexafluoride (SF 6 ) emissions are reported in kilograms.
  • GHG emissions are rounded to the nearest integer. Emissions reported as zero reflect this rounding.
  • GHG emissions associated with the corporate operations of wholly-owned subsidiaries Powerex and Powertech are included.
  • Fugitive SF 6 emissions from equipment controlled by the BC Transmission Corporation are not included.
  • Historical GHG emissions have been recalculated since the release of the F2007 GRI Comparative Index due to changes in inventory scope, improvements in data collection and updates to emission factors.
