Introduction Environmental sustainability (ES) is a current issue related to natural resource scarcity, pollution and climate change. Although operating rooms (ORs) comprise a small proportion of the entire hospital infrastructure, they significantly impact the environment. Anesthesiologists are ideally positioned to assume leadership, mitigating this negative impact regarding OR waste in the environment. We created a Green Team, comprising multidisciplinary professionals from different areas of a tertiary Portuguese medical center, and conducted a survey that was sent to all the institution's anesthesiologists to assess the current state of ES. Results From the sample of 133 participants, 101 responses were obtained. Concerning knowledge and training on ES, a significant portion of the respondents (66.7%) seem to attribute "great importance" to the subject. As to the greatest barrier to waste separation in the OR, several respondents highlighted the issues of "inadequate information/education/training" (62.6%) and "lack of support from hospital/OR in-chief/administration" (26.3%). Finally, among seven methods to raise awareness of ES, "training during residency" was the top choice for these professionals, with 52.5% of the votes. Discussion Most anesthesiologists who responded to the survey recognize the utmost importance of ES and have perceived the environmental impact of their anesthetic practices in the OR. Overall, this tendency is consistent with other international studies. Moreover, most of those surveyed separate waste at home and want to extend this practice -in a more structured approach- to their workplace, with an effective separation of anesthetic and general waste in the OR. Conclusion Professionals perceive barriers to performing green practices, whether the lack of environmental education and awareness, the absence of recycling containers or waste separation bags, or the lack of protocols and guidelines implementing these circuits. With the publication of this work, we aim to encourage other institutions to implement ES projects in their hospitals and ORs.
