Environmentally Extended Input-Output Analysis

Environmentally extended input-output (EEIO) analysis appends satellite accounts of physical environmental flows — greenhouse-gas emissions, energy, water, land, and materials — to a monetary input-output table so that environmental burdens can be allocated through supply chains to the final demand that ultimately drives them. By multiplying direct environmental-intensity coefficients by the Leontief inverse, EEIO computes the total burden embodied in each unit of final demand, providing the standard framework for consumption-based carbon footprints and emissions embodied in trade.
