Résumé	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.	Input-output analysis is a quantitative framework for representing the interdependence between the industries of an economy, introduced by Wassily Leontief in 1936. It records the flows of goods and services between sectors in a transactions table, derives fixed technical coefficients describing how much each industry buys from every other industry per unit of output, and inverts the resulting linear system to trace how an exogenous change in final demand ripples through the entire production structure.
