We are extremely grateful for the insightful and thought-provoking commentaries on our feature article.1 We have distilled four themes emerging from the commentaries, and we would also like to address one misunderstanding of our argument that has appeared. In our article, we explicitly acknowledge that major decisions relevant for climate protection take place at the mesolevels and macrolevels of healthcare, a point raised again in some of the commentaries.2–4 Climate protection is a societal issue, and we thank these authors for the concrete proposals of potential models to guide action. Yet, to us, it still makes sense to reflect simultaneously on the responsibilities that physicians have themselves. Without wanting to put the main responsibility on them, we argue it is important to start thinking about the scope of action that physicians actually have (or not have). As we have argued the need for climate action comes ever more into focus of society, we wanted to explore whether the professional ethics of the medical professionals needs to be amended.
