Standards Development
This standard specifies a data model for the exchange of Carbon Footprint of Products (CFP). It details how the data model is represented in the IEC Common Data Dictionary (CDD) with Asset Administration Shell (AAS) submodel.
The following are included in this standard:
- Specifications of the CFP exchange data model.
- The data model in IEC CDD as a database standard.
Note1: The specifications of CFP exchange data model will be aligned with CFP data exchange requirements from IEC 63372; also considering IEC 63366, ISO 22057, ISO 23387 and other existing CPF data models in industries such as Catena -X, World Business Council for Sustainable Development (WBCSD) PACT (Partnership for Carbon Transparency) Pathfinder Framework data model.
Note2: Consider developing the data format for the CFP exchange data model in IEC CDD in accordance with IEC 62474 developers table. This part with a guidance is separated into Part2.
Note3: The data format for communicating the CFP exchange data model such as XSD or JSON needs to be discussed. (Currently IEC SC3D supports the JSON, REST -API at the standard level. Functions are not implemented in current IEC CDD system.)
The necessity of a data exchange model for the Carbon Footprint of Products (CFP) is increasingly recognized across various industrial sectors due to its critical role in addressing environmental challenges. A standardized CFP exchange data model ensures t hat CFP result data from different sources is comparable and reliable. This standard is crucial for supporting transparent and regulatory-compliant carbon footprint data across product lifecycles and supply chains.
To address industrial demands, data spaces for CFP data exchange have been specified and developed. These data spaces, such as Gaia-X (Catena-X, Manufacturing-X,etc) and Ouranos Ecosystem, establish requirements for CFP calculation and data exchange. Simultaneously, Global consortiums are actively following trends to support CFP data exchange from both business and technical perspectives. A prominent example is the PACT (Partnership for Carbon Transparency) Pathfinder Framework, developed by the World Busin ess Council for Sustainable Development (WBCSD). Launched at COP26, the Pathfinder Framework version 2.0 provides comprehensive guidance for the accounting and exchange of product life cycle emissions across value chains.
The purpose of this standard is to specify a CFP exchange data model to support CFP data exchange throughout the lifecycle. According to discussions and reports from IEC TC111/SC3D JahG22 (CFP digitalization), requirements from both industrial demands and existing standards such as IEC 63372 will be considered. Additionally, the presentation of the CFP exchange data model in the IEC Common Data Dictionary (CDD) and its Asset Administration Shell (AAS) submodels will be defined accordingly.
While the description of this CFP exchange data model using the IEC 62474 developers table is out of the scope, it is noted that the IEC 62474 developers table, structured in harmony with IEC 61360 for IEC CDD, can represent the specified CFP exchange data model. However, the details will be discussed in another project.
As a horizontal standard, this standard relates to Guide 109 (Environmental Aspects) regarding "lifecycle thinking," "pollution prevention," "sustainable design," "compliance with environmental regulations," and "stakeholder engagement."
