The Earth’s climate is changing. In the UK and other northerly latitudes, seasonal transitions have become blurred and numerous extreme weather events are occurring here and devastating countries across the globe. In 2021, the World Health Organisation (WHO) stated that climate change is ‘the single biggest health threat facing humanity’.
The global temperature has increased by 1.0°C in the last 100 years and without human intervention it is predicted to rise by a further 2.0-6.0°C before the end of this century. For every decade since 1979, 5-10% of the arctic ice cap has irreversibly melted. Ironically this was the year of the world’s first climate conference and as part of the latest (COP26 - conference of the parties), 50 countries signed a pledge to develop low-carbon healthcare systems.
Healthcare is an extremely important factor, because if it were a single country, it would be the fifth biggest contributor to greenhouse gas emissions globally, behind China (27%), the USA (11%), India (6%) and Russia (4%).
The NHS is the largest single employer in Europe. It comprises 7% of the UK economy, accounts for 3.5% of all road traffic and is responsible for 4% of the nation's carbon emissions (>20 million tonnes/year!). All four nations have committed to a net zero NHS emissions target by 2045.
Procurement is the main contributor to the NHS’s carbon footprint at 62%. This differs from dentistry, where the three main carbon emission sources are:
- Patient and staff travel. 64.5%
- Procurement (e.g. materials, equipment, packaging and transport). 19%
- Energy (electricity and gas). 15.3%
In the hierarchy of sustainability measures, analysing and reducing procurement is a vital component of any carbon reduction strategy, second only to prevention.
