Characterization Factors

This part of the project documentation focuses on an information-oriented approach. Use it as a reference for the technical implementation of the pact_methodology project code.

CharacterizationFactors

Bases: str, Enum

The IPCC version of the GWP characterization factors used in the calculation of the PCF (see Pathfinder Framework Section 3.2.2). The value MUST be one of the following:

  • AR6: for the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC)
  • AR5: for the Fifth Assessment Report of the IPCC.

The set of characterization factor identifiers will likely change in future revisions. It is recommended to account for this when implementing the validation of this property.

For more information, please refer to the official documentation: https://wbcsd.github.io/tr/2023/data-exchange-protocol-20231207/#element-attrdef-carbonfootprint-characterizationfactors
