This paper shows the environmental load evaluation of a co-generation system with the aid of "ESS (Eco-load Standardization Scheme)" proposed by the authors. This scheme is applied to co-generation systems with different types of conditions. Further more, this evaluation includes some environmental issues, they are not only fossil fuels depletion and global warming due to CO2 emission but also rain acidification, natural resource depletion and so on. In thins evaluation, three kinds of fossil fuels are considered as a fuel in the evaluation of a co-generation system, comparing and analyzing about three fuels. We propose here the software "ESS (Eco-Load Standardization Scheme)" with cost analysis. A computer algorithm and software optimizing the environmental load and cost performance are accomplished by using a combined simplex and branch-bound technique. So, we can evaluate the environmental loads rapidly and easily with this software. As the results, an optimum eco-operation way for cogeneration system can be found.
