Sustainable Surgery: The Environmental Responsibility We Cannot Defer
Healthcare is one of the largest contributors to greenhouse gas emissions globally. Surgery is among the most resource-intensive activities within healthcare. Acknowledging this is not an attack on the value of what surgeons do — it is the beginning of a responsible conversation about how we do it better, for patients and for the planet simultaneously.
The global healthcare sector contributes approximately 4–5% of total greenhouse gas emissions — roughly equivalent to the aviation industry, and significantly more than many sectors that receive far greater environmental scrutiny. Within healthcare, elective surgery accounts for a disproportionate share of the footprint: energy-intensive operating theatres, single-use instrument trays, volatile anaesthetic gases with high global warming potential, and complex implant manufacturing and supply chains all contribute to a carbon profile that the surgical community is only beginning to systematically measure and address.
Where the surgical footprint lies
Life-cycle analyses of common orthopaedic procedures reveal that the largest single contributor to the carbon footprint of a joint replacement is not the theatre energy use or the anaesthetic gas — it is the manufactured implant and its packaging. This is a supply chain problem, which means it is also a procurement opportunity: health systems that include environmental performance metrics in implant procurement decisions have the purchasing power to incentivise manufacturers to reduce the embedded carbon of their products in ways that individual surgeons cannot.
Single-use surgical instrumentation — introduced partly for infection control and partly for logistical convenience — generates substantial waste volumes. The trend toward single-use for sterility assurance is clinically defensible, but it has been applied in many areas without systematic evaluation of whether the infection control benefit justifies the environmental cost. Reusable instrumentation with robust sterilisation protocols, where it meets safety standards, deserves reconsideration in the context of sustainability objectives.
The alignment of sustainability and quality
The most powerful sustainability intervention available to any surgical team is the most powerful quality improvement intervention as well: reducing unnecessary procedures. Every operation that does not produce meaningful patient benefit consumes theatre energy, generates instrument waste, uses implant resources, and contributes to the carbon footprint of the health system — without delivering the clinical value that justifies that cost. Rigorous indication setting, evidence-based patient selection, and robust pre-operative optimisation that reduces revision rates serve both clinical quality and environmental sustainability simultaneously.
Sustainable surgery is not about doing less for patients. It is about doing the right things, efficiently, with the minimum necessary resource — which is also the definition of excellent clinical practice.
The NHS commitment to net zero by 2040 provides a structural framework for this work in the UK. But the cultural shift — surgeons thinking of themselves as stewards not just of their patients' health but of the environmental resources their practice consumes — is the change that will outlast any specific regulatory framework. It begins with awareness, continues with measurement, and is realised through the incremental practice changes that collectively transform an institution's environmental performance.
