An Vercalsteren is team leader in one of the research teams in the unit Sustainable Materials Management. In this function, she coordinates both research projects and contract research, she expands and sustains networks and is actively involved in different research projects. An mainly is focussing on research related to life cycle thinking, value chain analysis, input-output analysis, sustainable production and consumption and indicators. As a part of this, she regularly cooperates with industry, governmental and research organizations on these topics, communicates frequently in different fora and publishes in scientific journals. An started her career as a researcher on life cycle assessment and eco-design projects, and built up a comprehensive knowledge (20 years experience) in the themes mentioned above.
The paper provides an integrated assessment of environmental and socio-economic effects arising from final consumption of food products by European households. Direct and indirect effects accumulated along the global supply chain are assessed by applying environmentally extended input–output analysis (EE-IOA). EXIOBASE 3.4 database is used as a source of detailed information on environmental pressures and world input–output transactions of intermediate and final goods and services. An original methodology to produce detailed allocation matrices to link IO data with household expenditure data is presented and applied. The results show a relative decoupling between environmental pressures and consumption over time and shows that European food consumption generates relatively less environmental pressures outside Europe (due to imports) than average European consumption. A methodological framework is defined to analyze the main driving forces by means of a structural decomposition analysis (SDA). The results of the SDA highlight that while technological developments and changes in the mix of consumed food products result in reductions in environmental pressures, this is offset by growth in consumption. The results highlight the importance of directing specific research and policy efforts towards food consumption to support the transition to a more sustainable food system in line with the objectives of the EU Farm to Fork Strategy.

There exists little evidence in the literature of the extent to which static environmentally extended multiregion input–output (EE-MRIO) studies actually contribute to political decision-making and policy formulation. This paper provides an overview of the reported applications of EE-MRIO analysis in an environmental context, either initiated by questions from policy makers or demonstrated by researchers. The applications are structured according to their scope and scale, the coverage of the DPSIR environmental policy framework (driving forces/pressures/state/impact/response), and the type of application (problem analysis/agenda setting, ex ante and ex post/monitoring). Results from interviews with policy makers (Belgium) show both their interest in IO-modelling and specific needs they have to make it more useful in their own context. The more experimental EE-IO models serve well for the early policy phase of problem analysis and agenda setting. Also, their use can prove the importance of strengthening international collaboration to develop internationally recognized EE-IO models.

At the request of the Public Waste Agency for the Flemish Region, the Flemish Institute for Technological Research performed a life cycle assessment (LCA), according to the International Organization for Standardization (ISO) 14040 procedures (ISO 1997, 1998, 2000, and ISO 2006), followed by an eco-efficiency analysis of four alternative types of drinking cups for use at public events. The results of the LCA study served as input for the eco-efficiency analysis in which the costs related to the four cup systems were studied and combined with the environmental impacts. The objective of this study was to gain insight into the current environmental impacts and costs related to existing systems for drinking cups at public events in Flanders (Belgium) in order to outline a well-founded policy with regard to this subject. Since the results of this comparative study are publicly available, a critical review was performed according to ISO 14040 (review by interested parties, using a review panel) after each stage (goal and scope, data inventory, impact analysis/interpretation, eco-efficiency analysis) during the study.
