The climate crisis is also a health crisis, with rising temperatures and environmental changes leading to devastating human health impacts including heat-related illness and increased mortality rates. Yet if healthcare were a country, it would be the world’s fifth-largest emitter of CO₂, accounting for over 4% of global emissions – more than the aviation or shipping sectors. To safeguard populations against the impacts of a changing climate, health systems must remain resilient to the increased disease burden and care needs created by climate change whilst improving their own environmental sustainability.

A sustainable health system improves population health by continually delivering the key functions of providing services, generating resources, financing and stewardship, incorporating principles of financial fairness, equity in access, responsiveness and efficiency of care, and does so in an environmentally sustainable manner.

A resilient health system is able to prevent, respond to, manage the health system impact of, and recover and learn from, acute and chronic crises (including, but not limited to, pandemic threats, climate change and economic and technological shocks), minimising their short- and long-term impacts on health, social and economic wellbeing.
