Overview of LCA and EIOLCA: Green Design and pollution prevention are proactive strategies to minimize the environmental burdens associated with a product or process without compromising functionality. Life cycle assessment (LCA) is an important tool used in pollution prevention and green design efforts. Selection of product design, materials, processes, reuse or recycling strategies, and final disposal options requires careful examination of energy and resource consumption as well as environmental discharges associated with each prevention or design alternative.
Input-output analysis has been used extensively for planning in the USA and throughout the world. Like the United States, many countries collect and publish input-output tables for their economies. The tables are used to calculate the resources and supply chain requirements required to support an increase in the demand for output of specific sectors like automobiles or food. The resulting estimates show the indirect increase in production, both for automobiles and for all the other sectors that supply products, directly or indirectly, to the automobile industry. In general, each sector contributes directly or indirectly to every other sector..
