    Implementation and development of an Internet based information exchange network between EU-member states, the European Commission and small and medium-sized enterprises (SME)
    (Sustainability in the Information Society, 2001) Avci, Nurten; Geldermann, Jutta; Rentz, Otto
    The EU-Solvent Directive (Council Directive 1999/13/EC on the limitation of emissions of VOC due to the use of organic solvents) lays down emission limit values for twenty different categories of installations using solvents. These limit values are determined depending on the applied production processes and the installation capacity. Therefore, companies are obliged to take measures in the near future to reduce emissions. Information about the way of compliance with the Directive is needed. Articles 7 and 8.5 of the EU-Solvent Directive shall ensure that an exchange of information between Member States and the activities concerning the use of organic substances and their potential substitutes takes place. The objective of a new and comprehensive information exchange forum is to provide high quality, focused information for all users affected by the Solvent Directive and to offer the possibility to upand download specific information for each activity and Member State.

    Linking Mass and Energy Flow Analysis with Time Management
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Geldermann, Jutta; Schollenberger, Hannes; Rentz, Otto
    High cost level of labour and stricter environmental legislation require high material efficiency, but also time efficiency in industrial production. In order to comply with new environmental requirements and to reduce material consumption, product substitutions are necessary, which often affect the current industrial processes. The adaptation of the processes influences mostly also the process duration and consequently the work flow. These changes are being investigated by time and motion studies. This paper proposes the combination of mass and energy flow analysis with results of time and motion studies. The data on time and material consumption can be evaluated simultaneously by using hierarchical IMPROVE®, which has been implemented for vehicle refinishing processes. The model facilitates an integrated process optimisation with regard to environmental and organisational aspects. Moreover, the interaction of changes in time (machine or labour time) and material use caused by product substitution or process changes can be considered. This enhanced approach for mass flow analysis allows for more meaningful environmental performance figures. Additionally, labour costs of process modifications or emission reduction measures can be assessed. Different strategies can be analysed by scenario techniques, supporting decision making and bench marking.

    Ökobilanzierung in der IT
    (HMD Praxis der Wirtschaftsinformatik: Vol. 47, No. 4, 2010) Schmidt, Nils-Holger; Thies, Florian; Kolbe, Lutz M.; Schmehl, Meike; Geldermann, Jutta
    Eine bewährte Methode zur Darstellung von Umwelteinflüssen durch Produkte und Dienstleistungen ist das Instrument der Ökobilanzierung. Sie hilft Entscheidungsträgern bei der Entwicklung und Verbesserung von Produkten und Dienstleistungen, bei der Unterstützung von politischen Entscheidungsprozessen und der Argumentationsunterstützung im Marketing. Das hier vorgestellte Beispiel illustriert das Vorgehen der Ökobilanzierung anhand von zwei Distributionsformen der Musikindustrie. Dabei wird gezeigt, dass die Distribution eines Musikalbums über das Internet einen ökologischen Vorteil aufweist, der jedoch aufgrund des hohen Energieverbrauchs von Rechenzentren gering ausfällt.
