Medical centers consume large amounts of electricity, water, food and building materials to provide high quality care. Among the medical centers, hospitals consume more energy and water than many industries and produce more waste. Medical centers should look for programs to reduce energy consumption, reduce environmental impact, and manage waste disposal and medical waste. Green innovation makes this possible for these centers. Green Innovation is a set of changes in production products and processes aimed at managing waste, environmentally friendly productivity, reducing greenhouse gas emissions, environmentally friendly design, and reducing environmental impact.In order to create a green innovation culture in the organization, in the first step, it is necessary to identify and prioritize the barriers to innovation in order to eliminate them.In this study, by examining the research literature and consulting experts, 15 sub-obstacles were identified in the form of 4 main management barriers, green suppliers, human and financial resources for medical centers.Then, using BWM method, their livelihood and ranking were considered according to 12 experts, and the results showed that managerial barriers and especially lack of management commitment are the most important obstacles for green innovation in medical centers. Therefore, first of all, this concept and its advantages and disadvantages should be explained to the managers, and then other obstacles should be removed.
