Notes:
- 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.
- 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 from electricity imports are not included.
- Under the B.C. Carbon Neutral Government Regulation, BC Hydro is required to account for indirect life-cycle emissions associated with paper consumption. In calendar year 2010, these emissions were estimated to be 0.23 kilotonnes CO2e.
- 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.
