DF 16 – Input-Output Life Cycle Assessment, from Theory to Applications
Whereas conventional process based LCA relies on the identification and quantification of physical flows of energy and matter, IO-LCA is a method based on the monetary flows induced in the economy and through all the supply chain by a product, process or activity. It allows quantifying energy consumption and pollutant releases that are linked to these monetary transactions according to the sectors (industries) to which these transactions are related. The IO table of coefficients is needed to estimate the monetary flows induced throughout the economy by the “ripple effect” emanating from a given sector output. For each sector, average emissions and the energy consumption per economic unit of output are required to assess the total environmental burdens.
The Process LCA can be considered as a more precise method within the limits of the system, as it relies on specific models of products and processes, unlike the IO-LCA which is based on mean values of emissions and energy consumption per economic unit of output for entire sectors of the economy. Nevertheless, Process LCA suffers from excessive cost, time, and information requirements. In addition to that, to define appropriate system’s boundaries, covering a sufficient percentage of the overall burden, is a difficult task that is not encountered when using IO-LCA. In fact, IO-LCA automatically allows considering the environmental burdens through all the supply chain, within the entire economy.
