Hospitals are major actors in the health care sector, and their duty is the safe treatment of patients. Thus, hospitals make an important contribution to the achievement of sustainability goals. However, they also have negative environmental impacts. Hospitals have difficulties responding to increasing environmental demands. The aim of this paper is to systematically delineate measures for hospitals' environmental management.We research EMAS-registered hospitals as pioneers in environmental management that have credibility through external validation. Based on 31 publicly available environmental statements, we analyze measures from the environmental programs. These measures are classified into general management approaches and measures that are related to input (energy, materials, and water) and output (waste, wastewater, and emissions).
