, unlike variables that are essentially symbolic or index numbers, provide a direct link to technology and to the physical world with which industrial ecology is concerned. Highest importance is placed on this data base; and the subsequent analysis directly exploits its empirical content rather than relying exclusively on its formal manipulation.

Instead, our models are "open," making use of exogenous information such as technological projections that are provided by engineers and other technical experts rather than being derived through the use of mathematical equations that describe idealized economic mechanisms. Through our work, my colleagues and I are trying to provide a systematic and operational description of structural economics as an economist's contribution to such new fields as industrial ecology, ecological economics, or the study of global change.

Common methodology needs to be developed to ensure that such studies meet the technical standards and analytic requirements of both communities. For the UNCED project mentioned above, case studies were carried out at the Institute for Economics Analysis for the following areas, which were chosen for their intensive use of energy: electricity generation, industrial energy conservation, household energy use, motor vehicle transportation, metal fabrication and processing, construction and its major material inputs, paper, and chemicals (Duchin et al., 1994, chapters 6-151.

The industrial ecologist is likely to start from a different ordering of priorities. The collaboration could prove fruitful in identifying areas for action that can satisfy the requirements of a relatively broad constituency, in quantifying the description of the inputs and outputs associated with alternative processes that might be adopted, and in providing a quantitative assessment of the economic and environmental implications of moving in these ~ .

First, by using the input-output case study methodology, it is possible to build a comprehensive data base from the bottom up based on technical assumptions. Only in this way are we able to arrive at an estimate for worldwide emissions of sulfur (in the last column of the table)
