Ecological Balances as an Instrument for Product Evaluation. The predecessor of today's increasingly important ecological balances was the Limits of Growth Report published by the Club of Rome in 1972. Ecological balances cover mass and energy flows and emissions from the raw materials via intermediates all the way to the end products, as well as waste disposal. This also includes the balance of ecological activity at all stages. The components of ecological balances are goal definition, material balance, action balance, balance evaluation, and optimisation analysis. The advantages of ecological balances are their fundamental acceptance by industry and environmental protection groups, clarity and essentially objective assessment, and the possibility of application to systems, comparison of equivalent products, systems, and services and comparison of null variants. Problems encountered with ecological balances arise, for example, because of frequently inaccessible data basis and because of the system definition.
