The EIO-LCA model as developed at Carnegie Mellon University has become a widely used tool in helping organizations and individuals better understand the life cycle and supply chain impacts of production and consumption. EIO-LCA links economic data on supply chain purchases with information on energy and other environmental factors to estimate implications of production from various industry sectors. Various EIO-LCA models for the US and other regions and countries are available at http://www.eiolca.net/. To date, more than one million uses of the EIO-LCA web models have occurred, making them a widely used resource.

Of particular interest is the 2002 United States EIO-LCA model, the latest benchmark model available with public data. In this model the latest energy and emissions information is combined with the supply chain economic data to give updated assessments of products and services to support environmental life cycle assessments and carbon footprinting studies. The 2002 model with its underlying data represents several person-years of effort in creating underlying estimates of energy use and emissions for all of the industry sectors and in adapting this information for use on the Internet in the 2002 EIO-LCA web model.
