1 Quo vadis MFA? , Wuppertal Material flows on a local level Material flow Analysis of the city of Hamburg Mark Hammer Stefan Giljum Friedrich Hinterberger mark.hammer@seri.at Quo vadis MFA? , Wuppertal Page 1 SERI

2 The NEDS Project Funded by SÖF social-ecologic research programme (Germany) Analysing natural, economic, discursive, and spatial aspects of sustainable development Models of the economic construction of ecological reality of European regions Discourse Analysis and MFA for three European regions (Hamburg, Vienna, Leipzig) Quo vadis MFA? , Wuppertal Page 2 SERI

3 Introduction i MFA following Eurostat (2001) i Years: i Indicators: DMI, DMC, PTB i Data sources: Regional statistics, statistics at province level; production and transport statistics Quo vadis MFA? , Wuppertal Page 3 SERI

4 Economy-wide MFA Domestic extraction: -fossil fuels -minerals -biomass Unused domestic extraction Material accumulation (net addition to stock) Economy Emissions Waste Unused domestic extraction Imports Exports Indirect flows associated to imports Recycling Indirect flows associated to exports Source: EUROSTAT (2001) Quo vadis MFA? , Wuppertal Page 4 SERI

5 Indicators DMI (Direct Material Input): i Domestic extraction + Imports DMC (Direct Material Consumption): i DMI exports Domestic extraction: -fossil fuels -minerals -biomass Economy PTB (Physical Trade Balance): i Imports exports Imports Exports Source: EUROSTAT (2001) Quo vadis MFA? , Wuppertal Page 5 SERI

13 Methodological problems i Data sources changed in the observed time period i Estimation methods had to be used i Some data was not directly available in tons (agricultural area, average yields) i Aggregation of data (mainly transport data) i No calculation of UDE and indirect flows Quo vadis MFA? , Wuppertal Page 13 SERI

14 Conclusions i Metropolitan MFA is dominated by imports and exports i Data availability and quality depends on administrative unit i Secrecy is a problem i Estimation methods have big influence Quo vadis MFA? , Wuppertal Page 14 SERI
