45th LCA Discussion Forum


Discussion forum on Life Cycle Assessment
15. September 2011, Ittigen (near Berne), Verwaltungszentrum des UVEK

Input-Output tables (IOT) are an economic methodology in order to investigate and analyse different production and consumption sectors in a given country or economic region. Such IOT can be extended with information on emissions and resource uses in order to analyse environmental impacts in relation to economic outputs or expenditures of production and consumption sectors. The instrument of environmentally-extended input-output-analysis (EE-IOA) thus allows the analysis of environmental impacts for whole countries better than life cycle assessment (LCA). By some researchers this type of analysis is also used as an alternative or supplement to LCA. Data from such an approach can be combined with LCA in hybrid-analysis in order to estimate the environmental impacts of inputs for which LCI data are missing.

So far environmentally extended input-output-analysis was rarely used in Switzerland mainly because of lack of data. A Swiss study has recently investigated the total environmental impacts of Swiss consumption and production with this approach (http://www.esu-services.ch/projects/ioa/). Within this project a hybrid-methodology was developed for assessing the imports by combining trade statistics and LCA data. This is of specific importance for a Swiss analysis because of the large dependency on trade with foreign countries. The inventory data are freely available in EcoSpold format and can thus be used by LCA practitioners (http://www.lc-inventories.ch). They cover all emissions and resources that are assessed with the ecological scarcity method 2006. The study shows that environmental impacts due to imports are more important than domestic impacts.

The forum will also discuss the economic background, uncertainties and possible improvement options of such an analysis. International speakers are invited and will provide a broader view on this approach. The application of EE-IOA data in different types of software will be explained in workshops.
We invite all LCA practitioners and other people interested in this approach and results from this study.

We look forward to meeting you in Berne!
