Abstract
The climate crisis has been identified as the largest threat to human health; paradoxically, the healthcare sector is responsible for 5% of the global greenhouse gas emissions that are driving this crisis. These emissions are largely due to carbon-intensive facilities, energy use, complex global supply chains, transportation and pharmaceuticals. In its role of safeguarding the health of both current and future populations, the healthcare sector must take actions to minimise its environmental impact. Strategies for emission reduction include sustainable infrastructure, clinical practice innovations, and procurement and supply chain reform. This article aims to examine current evidence on the health impacts of climate change and explore strategies through which the healthcare sector can reduce its environmental impact while continuing to deliver high-quality care.
