Electricity Emission Intensity Factors for Grid-Connected Entities
The Director under the Greenhouse Gas Industrial Reporting and Control Act (GGIRCA) publishes annually a set of greenhouse gas (GHG) emission intensity factors for electricity use. The published factors must be used by grid-connected entities in quantifying GHG emissions of electricity which is not self-generated, for the following:
- Offset projects as prescribed in relevant GHG emission offset protocols;
- Other customers of BC Hydro and FortisBC who wish to calculate the GHG emissions associated with their electricity use.
The calculation of emissions intensity is based solely on estimates of physical emissions and does not represent any claim or right to the environmental attributes of the electricity delivered to customers on the B.C. integrated grid. The environmental attributes associated with this electricity may have been retained by, sold or transferred to, third parties inside or outside of British Columbia.
Electricity in B.C. is supplied to customers through the Integrated grid (southern and western B.C.), the Fort Nelson grid (northeast B.C.), and through community generating stations for isolated grid communities (throughout B.C.).

B.C.’s Grid Electricity GHG Emission Intensity Factors for 2018, in tonnes CO2-equivalent per Gigawatt-hour (tCO2e/GWh):
· For the Integrated grid: 25.3
· For the Fort Nelson grid: 572
B.C.’s Grid Electricity GHG Emission Intensity Factors for 2017, in tonnes CO2-equivalent per Gigawatt-hour (tCO2e/GWh):
· For the Integrated grid: 31.7
· For the Fort Nelson grid: 559
