In the realm of medical ethics, the foundational principle of respecting patient autonomy holds significant importance, often emerging as a central concern in numerous ethically complex cases, as authorizing medical assistance in dying or healthy limb amputation on patient request. Even though advocates for either alternative regularly utilize prima facie principles to resolve ethical dilemmas, the interplay between these principles is often the core of the theoretical frameworks. As the ramifications of the sustainability crisis become increasingly evident, there is a growing need to integrate awareness for sustainability into medical decision-making, thus reintroducing potential conflict with patient autonomy. The contention of this study is that the ethical standards established in the 20th century may not adequately address the challenges that have arisen in the 21st century. The author suggests an advanced perception of patient autonomy that prioritizes fostering patients’ knowledge, self-awareness, and sense of responsibility, going beyond a sole focus on their intrinsic values. Empowering patients could serve as a tool to align patient autonomy, beneficence, and the aim to reduce resource consumption.
