OpenIO-Canada emission factors

Emission factors for the openIO-Canada v2.11 database, for the reference year 2022. They cover 473 commodities across 13 provinces.

These factors are per Canadian dollar (e.g., kgCO2eq/CAD or CTUe/CAD). They are in purchaser price, they can thus directly be used with typically available purchase information, without needing pre-treatment. Finally, they were generated using the capital-endogenized version of openIO-Canada, the factors therefore include impacts from infrastructure.

There are 44 indicators that are covered through the IMPACT World+ v2.1 life cycle impact assessment (LCIA) methodology. The typical carbon footprint indicator is called "Climate change, short term". For users looking to do more than a simple carbon footprint, they are encouraged to read more about the concept of midpoint and area of protection, as applied in IW+ (https://www.impactworldplus.org/).

Factors are also provided as disaggregated between the 3 scopes as define in the GHG protocol. Note however, that since it is based on Input-Output, these are cradle-to-gate emission factors, which thus only cover the upstream of scope 3 and not the downstream.
