An estimate of the industrial metabolism of the Piedmont region (Italy) using the environmental input-output analysis and the ecological footprint TIES 2009 - Bologna Pancrazio Bertaccini , Marco Bagliani IRES (Istituto Ricerche Economico Sociali) Piemonte IRIS (Istituto di Ricerche Interdisclipinari sulla Sostenibilità)

7. The input output analysis (2) X is the total output z ij are the sectorial exchanges Y is the final demand (C+E) Technical coefficients representing the amount of good from sector i needed to produce directly one unit of good from sector j The Leontiev inverse Matrix, represent the total direct and indirect requirements of any industry j supplied by other industries i within the region in order for industry j to be able to deliver €1 worth of output to final demand Pancrazio Bertaccini, IRES Piemonte …… …… …… … … …

Portion of footprint for different household Food Electricity Vehicle fuel Pancrazio Bertaccini, IRES Piemonte  Averaged per capita Ecological footprint for the Italian inhabitant: using the ecological footprint related to a sector product  We can obtain the coefficients related to 1€ of production that makes us able to estimate the amount of the products produced by that sector bought in any subregional area where expenditure data are available

The Piedmont case study (2001) Vehicles fuel Methane Electricity Centrally heated Maintenance Purchase of vehicles Pancrazio Bertaccini, IRES Piemonte Using the coefficients for 1€ of sector production we can obtain a detailed break-down of the Piedmont inhabitant consumption based on the real expenditure Food
