The climate crisis - actions to prioritize for anaesthesiologists.

Purpose of review: Climate change is the biggest threat to human health and survival in the twenty-first century. Emissions associated with healthcare contribute to climate change and there are many personal and professional actions that can reduce carbon emissions. This review highlights why action is necessary and what anaesthetists and healthcare workers can do.

Recent findings: Encouraging continuing research regarding sustainable anaesthesia and expanding education at all levels to include climate action is key. Professionally, actions include limiting use of single-use equipment, reducing reliance on volatile gas inhalational anaesthesia, and adopting low fresh gas flow techniques. Personal actions such as climate-conscious travelling, spending, and eating are important, especially when shared to create climate positive movements.

Summary: This article shows that, while patient safety and quality of care must remain healthcare's top priority, considering the climate implications of care is part of that duty. Many actions that reduce the carbon impact of care simultaneously improve the quality of care and reduce financial cost. More research into sustainable healthcare is needed. Departments and hospitals and must create environments in which climate conversations are welcomed and can result in positive advancements.
