Barriers Found in the Integrated Implementation of Energy and Environmental Management Systems Through ISO 50001 and ISO 14001

The relationship between energy and environment has been known for a long. Nevertheless, the synergy among energy and environmental management systems is still few explored in the literature. In this sense, the objective of the present work is to shed light on the barriers found in the literature for the integrated implementation of the ISO 50001 and ISO 14001 international standards. A systematic search of scientific papers was developed in several databases, such as Scopus, ScienceDirect and Web of Sciences among others. After discarding book chapters and articles non-related to ISO 50001 and ISO 14001 integrated management systems, 14 papers were selected, in which a total of 30 barriers were mentioned. Classifying similar barriers, 13 categories were obtained. With 20%, the most referred barrier was the scarcity of resources, including financing, data, and time; followed by deficient leadership strategies and/or commitment, with 13%. The results of this research show that management teams need to become aware that the synergy between energy and environmental management systems can bring competitive advantages in the medium and long term, by optimizing resources, increasing efficiency, and achieving sustainability. The findings presented can also contribute to policymakers and certification bodies for promoting sustainable development.
