Anesthetic gases are potent greenhouse gases, which are currently released into the atmosphere where they remain for many years. Strategies to reduce the carbon footprint in anesthesiology without compromising patient safety are urgently needed. Since 2020 several departments of anesthesiology have installed anesthetic gas capture systems with which anesthetic gases can be collected. This article aims to describe the anesthetic gas capture system CONTRAfluran™ and to give an overview of the first experiences in four departments of anesthesiology working with the new device in the daily clinical routine. The CONTRAfluran™ system presents a new concept in the surgical setting that has the potential to reduce the carbon footprint in anesthesiology; however, in order to accurately estimate CO2 equivalent savings, more information concerning the reprocessing and data on the pharmacokinetics of anesthetic gases are needed. Application of the CONTRAfluran™ system in daily clinical routine is feasible when anesthesiologists are aware of specific issues. In order to minimize the carbon footprint, it remains essential to implement the specific recommendations in the position paper of the German Society of Anaesthesiology and Intensive Care medicine (DGAI) and the Professional Association of German Anaesthesiologists (BDA) on ecological sustainability in anesthesiology and intensive care medicine and to support further research.

To counteract the effects of climate change and biodiversity loss, sustainable transformations of societal systems and processes, as well as spatial planning, are required. Ecosystem services are considered as a concept that could transform the management of natural resources towards more sustainability. On the basis of six application-oriented research projects, this paper analyses the extent to which transformation has played a role in planning-related research on ecosystem services so far and what potential experts see for contributing to transformative change in the context of spatial planning by means of ecosystem services. The current research projects on ecosystem services predominantly do not directly refer to transformative processes and strive for changes within the existing planning framework. However, if research would be designed accordingly, it would be possible to contribute to transformative processes. Among other things, the concept of ecosystemservices can be used to promote systemthinking, cross sectorial boundaries, or involve civic stakeholders to a greater extent. Experiments in research could be the basis for transforming the planning system starting at the niche level. [ABSTRACT FROM AUTHOR]
