The OECD conducted a review of available approaches to calculate material footprints, which revealed that the scientific and statistical community has not yet agreed on the reliability of these different approaches. Furthermore, results for certain countries or world regions differ significantly when calculated with different approaches. This project continues on previous work by expanding the knowledge on the causes for differences in results from calculations of material footprints; for this, the methods comparison is amended by a calculation of material footprints using the OECD MRIO model.
The comparison allows to identify the causes for differences in results and to qualify approaches and models with regard to their validity, robustness and reliability. Based on this, the project team develops a set of recommendations for the required steps to arrive at robust measures of material footprints, which then can inform policy debates on sustainable resource use, resource efficiency, and green economy.
