Green bioethics is an area of research and scholarship that examines the impact of healthcare practices and policies on the environment and emphasises environmental values, such as ecological sustainability and stewardship. Some green bioethicists have argued that healthcare providers should inform patients about the environmental impacts of treatments and advocate for options that minimise adverse impacts. While disclosure of information pertaining to the environmental impacts of treatments could facilitate autonomous decision-making and strengthen the patient-provider relationship in situations where patients have clearly expressed environmental concerns, it may have the opposite effect in other situations if makes patients feel like they are being judged or manipulated. We argue, therefore, that there is not a generalisable duty to disclose environmental impact information to all patients during the consent process. Providers who practice green bioethics should focus on advocating for system-level changes in healthcare financing, organisation and delivery and use discretion when bringing up environmental concerns in their encounters with patients.
