     recent global attention to the challenges of environmental protection is forcing firms and governments to evaluate, rank, and select eco-efficient technologies. technologies may consume inputs to produce both desirable and undesirable outputs. it seems that the data envelopment analysis (dea) is a proper method to evaluate eco-efficient technologies. there are some dea extensions for dealing with undesirable output, and sometimes it is difficult to choose a suitable model to evaluate the technologies. the challenge becomes much more complex when the outcomes of models are not similar. in such a condition, subjective selection of alternative dea models may lead to deviation from an optimal decision. accordingly, the objective of this paper is to develop a combined model to include all characters of the previous dea techniques in a flexible model to select optimum eco-efficient technology in the presence of undesirable outputs. a case study demonstrates the application of proposed procedure.
