Gap Analysis for CO Accounting Tool by Integrating Enterprise Resource Planning System Information.

Detailed carbon accounting is the foundation for reducing CO2 emissions in manufacturing companies. However, existing accounting approaches are primarily based on manual data preparation, although manufacturing companies already have a variety of IT systems and resulting data available. The gap analysis carried out based on the GHG Protocol and an reference ERP system shows how much of the required information for CO2 accounting can be integrated from an ERP system. The ERP system can cover 20% of the required information. The information availability can be increased to 49% through additionally identified modifications of the ERP system. Integrating the CO2 accounting tool with other systems of the IT landscape, e.g. Energy Information System, enables an additional increase.
