This dataset published by Environment and Climate Change Canada provides electricity emission factors based on Canada’s official greenhouse gas inventory, including both newly reported data and retrospective updates to historical years.

Carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) emission factors are sourced from Tables A7-1 to A7-14. These tables report electricity generation emissions by province and territory and represent production-based electricity emission intensities, reflecting the electricity production mix at the provincial and territorial level.

Transmission and distribution (T&D) losses are not explicitly provided in this dataset and are instead derived using a separate calculation based on Canada’s official electricity intensity data. Specifically, T&D emission factors are calculated as the difference between electricity generation emission intensity (production-based) and electricity consumption emission intensity, using total emissions and electricity generation/consumption values from the National Inventory Report. This approach ensures that losses occurring during electricity transmission and distribution, are accounted for while avoiding underestimation due to rounding or aggregated reporting.

The data is aligned with the Intergovernmental Panel on Climate Change Guidelines for National Greenhouse Gas Inventories.

The emission factors are production-based and therefore do not account for electricity imports and exports.

Transmission and distribution (T&D) losses are not directly reported and are instead derived using a separate calculation, which may introduce additional uncertainty and reduce transparency compared to directly reported values.
