Australian and Canadian clinicians' views and application of 'carbon health literacy': a qualitative study

Clinical care contributes to at least 50% of the greenhouse gas (GHG) emissions of healthcare. This includes the 40% of healthcare that is harmful or low value, adding avoidable emissions without improving health or quality of care. Clinicians are well-placed to mitigate emissions associated with the provision of clinical care. This study aimed to explore clinicians' views on a new construct we have termed 'carbon health literacy' to understand how knowledge, skills and capacities related to the emissions of clinical care has application in clinical practice.

Qualitative interviews were conducted between August 2022 and February 2023 with clinicians from Australia (n = 15) and Canada (n = 13). Clinicians with an interest in climate change and healthcare sustainability were sampled from a variety of clinical specialty areas, such as primary care, nursing, anaesthetics, and emergency. Clinicians were recruited through advertising on social media and via professional networks. A pre-piloted interview schedule was used to guide the interviews. Interviews were audio recorded, transcribed verbatim and analysed using framework analysis.

Participants viewed carbon health literacy as an increasingly important skill for clinicians to have or acquire, though they reported that the level of carbon health literacy and knowledge needed varies by job roles, clinical specialty areas, and individual capacity to generate healthcare system change. Many clinicians reported implementing strategies to mitigate their work-related GHG emissions, such as reducing waste or choosing lower carbon commuting options. There was limited awareness of reducing low-value care as a strategy to decrease emissions. All participants had encountered barriers to providing low-carbon care, including managing patient expectations, inadequate training and information, and limited capacity to generate system change in their organisational roles.

To support the delivery of high value low carbon healthcare, work is needed to build the carbon health literacy of clinicians and remove other barriers currently impeding their capacity to practice and promote sustainable clinical care.
