    Comparing Data Management in LCI Databases
    (EnviroInfo Dessau 2012, Part 2: Open Data and Industrial Ecological Management, 2012) Severith, Marcel; Manthey, Christian
    Life Cycle Assessment (LCA) is a widely accepted method for analysing the environmental aspects of goods and services. Life Cycle Inventory (LCI) datasets document the various involved material and energy flows, forming the basis of every LCA study. Today, a plurality of databases providing LCI data exists. Data delivered by these databases has to be sound as well as suitable for the specific application. Therefore, LCA practitioners request highquality, regularly updated and verified data with maximum information content and maximum transparency of backgrounds and assumptions. These needs have to be satisfied by the database vendors with the help of adequate data management. Therefore, this paper derives aspects of data management in the LCI context, enabling the comparison of specific database systems. The developed framework is verified by applying it to compare the two databases ecoinvent and ProBas.

    Integrating ERP and Environmental Information Systems – the Case of Life Cycle Inventories
    (Innovations in Sharing Environmental Observations and Information, 2011) Severith, Marcel; Hilty, Lorenz M.
    This paper takes the life cycle inventory database ecoinvent as an example of the integration of ERP and environmental information systems. A reference model describes the ERP-integrated creation of life cycle assessments based on ecoinvent data. The main challenges to implement the reference model from the viewpoint of ecoinvent are identified and approaches for a solution presented. First, an outline for an ontology enhancing ecoinvent metadata is given to help bridge the so-called semantic gap. Second, the basic web services needed to attach to a service-oriented architecture are described.
