摘要:The eco-efficiency concept makes reference to the process that looks for maximizing the effectiveness and efficiency of the managerial activity and minimizing their impact on the environment. Traditionally it has been thought alone in the negative effects on the costs of being responsible with the environment, forgetting the important advantages of productivity that counteract those costs and that can be obtained thanks to the innovation. The paper deals with the question: in which ways the concept of eco-efficiency can make a valuable contribution to the environmental knowledge for Romanian SMEs?
