Environmental Sustainability and Surgery

The NHS currently emits over 1/3 of the UK’s public sector emissions and produces 590,000 tonnes of waste. This makes it the largest public sector contributor to climate change in Europe, contributing equal municipal waste to the whole of Luxembourg. 

Surgery is the most resource intensive aspect of healthcare, responsible for a large portion of these emissions. A study published by the Lancet estimates that theatres are between three and six times more energy intensive than equivalently sized other areas of the hospital due to their heating, ventilation, and air conditioning requirements. Furthermore, one operating theatre suite in a UK teaching hospital had a comparable annual carbon footprint to over 2,000 homes.

Sustainability Champions

In recognition of the clear and present danger that the climate emergency poses, the Royal College of Surgeons of Edinburgh has put together a working group of “Sustainability Champions” to devise practical solutions,  helping the surgical profession to understand and reduce its environmental impact.

The Group comprises:

  • Katie Hurst (Chair) - General Surgery SpR within Thames Valley, currently undertaking a DPhil with the University of Oxford. ​Past member of RCSEd trainees committee
  • Professor Michael Griffin OBE – President of the Royal College of Surgeons of Edinburgh.
  • Nathan Stephens - Consultant Oesophagogastric Surgeon at the Royal Liverpool University Hospital and current Chair of the RCSEd Younger Fellows’ Committee.
  • Jasmine Winter Beatty - Surgical Registrar in the North-West London deanery and Clinical Research Fellow at ICHNT, pursuing a PhD on the application of digital technologies and AI in surgery and the essential role of sustainability in surgical innovation.
  • James Chu - ICAL medical student in urgent and emergency care at Treliske Emergency Department. Affiliate and sustainability champion of RCSEd.
  • Haroon Rehman – Chair of the RCSEd’s Trainees Committee and a Specialty Registrar (ST8) in Trauma & Orthopaedic Surgery based at Wrightington Hospital

Starting the Conversation and Raising Awareness

The destruction of the only life system known to support human life poses significant dangers to our health with consequent added burdens for the NHS. Heat-related mortality in those over 65-years-old has increased by 53.7%, over the past 20 years. 

Air Pollution is now the biggest killer worldwide causing >7m deaths/yr.

The NHS is the largest public sector contributor: its carbon footprint is 5% of whole of UK! Of the whole NHS footprint 5% is caused by volatile anaesthetic gases, 10% energy, 10% instruments & equipment.

Did you know the average carbon footprint of a UK operation is equivalent to driving 435 miles? That’s more than driving from London to the COP26 in Glasgow! Surgery is 3-6 times more energy intense than any other hospital department. Good news: you can enact change in your department to mitigate this! 

Where to start: within surgery anaesthetic gases account for 42% of emissions; of the remaining carbon footprint, energy accounts for 58% and consumables for 32%. Here are some tips for QUICK ACTIONS that you can take in your department and at home!

What can you do? Find out about your trust's Green Plan. Ask if your Trust has declared a Climate emergency? Does your Trust have a Sustainability team, and can you get involved? Get the conversation started and don’t be afraid to implement small changes! Keep an eye on our page for more information and resources!

Steps That Can Improve Your Environmental Impact

Steps to improve your carbon footprint


Upcoming Events: 

  • The Association of Anaesthetists have been collaborating with us at the Centre for Sustainable Healthcare by hosting a monthly webinar titled Sharing hour. This is facilitated by the National Anaesthetic fellow in Sustainability, Dr Jason Gandhi. Each month, the theme varies and although the primary audience is for Anaesthetists, participation from other specialities is very much encouraged. 

    The Sharing Hour is an opportunity for theatre colleagues and beyond to openly share thoughts, ideas and ongoing sustainability projects in a safe space. It is not a didactic teaching hour but more of a platform to network, bounce suggestions off one another and have a general sustainability conversation. 

    Previous themes have included Greener theatres, beyond anaesthetic gases and the upcoming sharing hour will be themed ‘reusable Vs disposable equipment’ on Tuesday 1 March at 7pm

    Only through collaboration will we be able to mount a sustained response in aiming for net zero.  If you would like to attend, then please purchase a free ticket through eventbrite here
