Disaggregating input-output tables for the calculation of raw material footprints — 2021 edition - Products Statistical working papers

This report provides guidance on the use of the FIGARO multi-regional input-output dataset for estimation and in-depth analysis of material flow indicators in raw material equivalents (RME). The report reviews existing studies focused on aggregation error and disaggregation methods for input-output tables and it presents findings from our calculations based on the current Eurostat RME model. We conclude that monetary models are not able to provide sufficiently accurate results even at high sectoral disaggregation. We propose using a hybrid unit model in which monetary sales structures are replaced by physical sales structures for selected products.
