investment, public expenditures and exports decisions, allows us to isolate the role of the families in the environmental sustainability of the planet and the effects over the inequality. The impact will depend on the different propensities to consume of the families () and on different consumption patterns. The literature has evaluated the possibility of reducing those footprints through the identification and strengthen of more sustainable patterns. Some examples are the papers of about food miles, and or about water footprint. The voluntary reduction of families consumption levels or the increasing collaborative consumption, regulated by the European Union (), could be examples of voluntary changes in the consumption patterns towards a more responsible consumption. However, our paper is referred to forced changes in the consumption due to family´s income reduction and to changes in the income distribution generated by the economic crisis. 2. Methodology. The matrix of factor content, direct and indirect, in an MRIO context is obtained from the expression 1 (): [1] Where refers to the diagonalized direct emissions coefficient or factor content (CO2 emissions, materials, added value, employment, per unit of sector output, is the …) matrix of total (domestic and imported) technical coefficients, is the Leontief inverse and the amount of direct and indirect inputs per unit of output produced that satisfies final demand, is the diagonal matrix of final demand, is the diagonal matrix of domestic final goods (consumption, investment and public expenditure) and is the diagonal matrix of exported final goods. By columns, the matrix [1] for the region r quantifies the factor content footprint of the region (, ). In this paper, we considered as factor content, CO2 emissions and materials, and we talk about carbon footprint and materials footprint of a region. The parceling of the Leontief inverse and final demand is useful to isolate the domestic and imported factor content demand (). For this purpose, the domestic multiplier is
