Footnotes:

1) Includes manufactured gases, other petroleum products, other fuels and station service.
2) Emissions per unit of electricity generated. This GHG emissions factor is applied to the end-use electricity consumption for the sectoral analysis including electricity-related emissions.
3) Emissions per unit of energy used to produce electricity. The difference between the two emissions factors represents conversion losses (energy used to produce electricity versus the amount of electricity generated).
