Cross-Cutting Topic 5: Modelling, Data Management (incl. Life Cycle Assessment)


  • To identify and exploit synergy effects between project partners from the areas of river basin-related modelling and life cycle assessment
  • with regards to modelling: to identify synergies and interfaces of modelling approaches; to discuss data needs and data sharing
  • with regards to Life Cycle Assessment: to develop common assumptions regarding the objective and the scope (system boundaries) of the assessments

Status of work

The cross-cutting topic is divided into two sub-topics: River basin-related modelling and life cycle assessment. A first exchange of experience took place in both areas. The first workshop on river basin-related modelling took place in March 2019, at which the modelling approaches used, as well as the associated data basis, were presented. For further exchange, fact sheets of the models were developed.

In the field of life cycle assessments, telephone conferences and a workshop were held for exchange purposes. Thereby, synergy and harmonisation potentials for various topics have been pointed out:

Functional units, system boundaries for the assessments, common assumptions e.g. regarding the handling of multifunctionality or the definition of end-of-life scenarios, common database (e.g. choice of life cycle assessment databases, plastic sources such as tyre abrasion and textiles) and others. 


Following the first kick-off meetings, intensified cooperation is planned for both subject areas. In this way, possible synergy effects between the projects are to be enhanced. An additional workshop on life cycle assessment is planned for the end of 2019.

In the sub-topic of life cycle assessment, a publication is planned for the jointly developed harmonisation approaches.
