Environment and sustainability

The College is committed to embedding sustainability in everything we do.

It is widely accepted that current use of global resources is not sustainable without compromising the wellbeing of current and future generations. Therefore, the College and anaesthetists must minimise the environmental impact of our lives and work.

The Lancet Report 2015 suggested that addressing climate change is the greatest opportunity to improve global health. Man-anthropomorphic CO2 and other greenhouse gas emissions are significant drivers of climate change. The NHS contributes significantly to the UK’s CO2 production, with estimates suggesting as much as five per cent of CO2e based on estimates for NHS procurement, staff and patient travel, infrastructure and waste management.

Modern anaesthetic gases are expelled into the atmosphere and contribute to climate change. They also represent five per cent of the carbon footprint for all acute NHS organisations, with the carbon footprint of anaesthetic gases estimated to be 0.47 MtCO2e. Less than one-quarter of this carbon impact is from use of volatile agents (desflurane, sevoflurane and isoflurane) and more than three-quarters from nitrous oxide (N2O). A third of the N2O use comes from theatres, with the remaining two-thirds from use in obstetrics and emergency care. The global warming effect of volatile agents differs by a factor of 20. At one litre FGF a MAC-hour of the more potent sevoflurane has a CO2e of 1.1kg CO2e compared with 73kg for desflurane, the equivalent car travel being eight vs 487km.

Through the work of our President's Environmental Advisor, Dr Tom Pierce, the College aligns itself with relevant national and international initiatives related to anaesthesia and the wider NHS aimed at mitigating further global temperature rise and climate change, including being a founder member of the UK Health Alliance on Climate Change. Tom works closely with the College Council lead for sustainability, Dr Lucy Williams.

The College is already committed to promotion of sustainability through our Strategic Plan 2018–2021, our Sustainability Strategy 2019–2022, and the Joint Environmental Policy Statement with the Association of Anaesthetists. We support implementation of initiatives which align with our College strategy of perioperative care, and promote efficient and cost-effective use of healthcare resources whilst reducing variability of care and improving patient outcomes.

The College will align itself with relevant national and international initiatives aimed at mitigating further global temperature rise and climate change. We will aim to minimise the environmental impact of our work as an organisation and move towards achieving the ISO 14001 standard.
