Technical environmental innovations (TEIs), also called eco-innovations, are key tools within environmental management systems owing to their potential contribution in reducing environmental degradation. Thus, the importance of the use of TEIs in the hospitality industry was discussed in this study. A qualitative-method approach was used. To that end, six hotel managers from Peruvian accommodation establishments were interviewed. It was found that the use of environmental process innovations reduces operating costs and environmental discharges. However, management indicators are required to measure the real impact on the environment. Despite the benefits of TEIs, their use has not yet become widespread in the Peruvian hospitality industry owing to internal barriers, such as the company’s size and investment capacity, and external barriers, such as the absence of a policy framework established by public management entities and the lack of suppliers.
