This tutorial provides step-by-step instructions on how to enter data into the EIO-LCA model and the process behind choosing the data to enter. Then, the tutorial describes how to read and interpret results. The blue boxes on the right provide additional notes about the functions of the EIO-LCA model and links to additional information.

  Step 1: Choose a model

The first step in using the EIO-LCA model is to select the model year and country for industry data from the drop down list. Models exist for the years 1992, 1997, and 2002. The most recent data available is from 2002, and this tutorial will focus on the use of the United States 2002 model. Data is also available for Germany, China, Spain, and Canada and can be selected from the model year drop down list.

It is important to note the distinction between selecting the 2002 model for producer or purchaser prices. Producer prices refer to the "cradle to gate" costs associated with a product that include everything from the extraction of raw materials up to the point at which a good leaves the production floor. Purchaser prices, however, include everything in the producer price as well as the distribution costs required to get the product to the final consumer.
