A key challenge in preparing a life cycle assessment is the collection and availability of accurate and comprehensive data along the entire supply chain. The integration of data from different suppliers and sub-suppliers as well as the harmonization of different data formats and sources can be complex and time-consuming. Early integration of all parties into a central platform can help here. Defined role and rights concepts make it easy to regulate which data can be viewed by which actor. Other challenges include analyzing and interpreting the results and dealing with uncertainties in the data. A good software solution should address and solve all of these challenges.
