Climate-smart healthcare: hospitals as sustainability leaders

Health and climate are one agenda. Health systems worldwide are joining a WHO-convened movement — the Alliance for Transformative Action on Climate and Health (ATACH) — through which countries commit to building climate-resilient and sustainable, low-carbon health systems, carrying forward the COP26 Health Programme.^[1] For hospitals, this is strategy as much as stewardship: resilience protects continuity of care, and efficiency returns resources to the bedside.

Where hospitals act first

• Energy and estates. Efficiency upgrades, smarter buildings and renewable sourcing — often the fastest wins with the clearest payback.
• Clinical hotspots. Thoughtful choices in anaesthetic gases, inhalers and single-use practice reduce footprint without compromising care — clinician-led by nature.
• Supply chain engagement. Procurement that asks sustainability questions moves markets far beyond any one institution’s walls.
• Resilience planning. Heatwaves, storms and supply disruptions are health events; climate-ready hospitals plan for them as core preparedness.
• Waste and water. Segregation, circularity and consumption discipline — visible daily practices that build culture.

Leading the change

Sustainability succeeds as a managed programme: board sponsorship, baseline measurement, prioritised projects and progress reporting. It also engages staff powerfully — few initiatives unite clinical and non-clinical teams like one that connects daily work to a healthier world.

Health care meets its own footprint

The healthcare sector’s environmental awakening followed an uncomfortable audit: analyses across the last decade established that if global healthcare were a country, its greenhouse-gas emissions would rank among the largest national emitters — a striking position for a sector devoted to health, given the WHO’s consistent identification of climate change as a fundamental threat to human health. The response has moved from declaration to engineering. England’s NHS became in 2020 the first national health system to commit to net-zero targets with a costed delivery plan, dozens of countries have since joined WHO-convened commitments on climate-resilient, low-carbon health systems, and sustainability criteria are entering hospital accreditation and procurement worldwide.

Where hospitals find their emissions — and their wins

• Energy and estates. Heating, cooling and power dominate direct footprints; efficiency retrofits and renewable procurement are the classic first wave, often self-funding over asset lifetimes.
• Anaesthetic gases and inhalers. A handful of clinical choices carry outsized climate weight; switching where clinically appropriate has become the emblematic quick win, led by clinicians rather than imposed on them.
• The supply chain, above all. Most healthcare emissions hide in purchased goods and services — pharmaceuticals, devices, food, logistics — making procurement policy the sector’s most powerful environmental instrument.
• Circularity over disposability. Reprocessing, reusables where safe, and waste-stream discipline — reversing a decades-long drift toward single-use defaults, with infection safety as the non-negotiable boundary.
• Care-model design. Prevention, digital consultation and care closer to home reduce emissions and burden together — sustainability and value pointing, conveniently, in the same direction.

Looking ahead

Climate-smart healthcare is professionalising fast: sustainability officers joining executive teams, carbon literacy entering clinical education, and reporting frameworks making footprints comparable across institutions. The strategic reading for hospital leaders is straightforward — environmental performance is becoming a dimension of quality, scrutinised by accreditors, regulators, staff and communities alike, and the institutions treating it as core management discipline are building reputational and financial resilience in the same motion.
