Sustainability at PDSE
Sustainability is one of PDSE’s seven core organisational values. We are alert to our own environmental impacts and as an organisation and are engaging with our moral obligation, as all healthcare organisations have, to rapidly improve the Environmental Sustainability of services – both in respect to the patients, staff and society of today, but of future generations as well.
Our Greenhouse Gas Emissions
PDSE has been building understanding of its greenhouse gas emissions over the last three financial years. In October 2024 we reported on our Scope 1 to 3 emissions, in alignment with all 17 categories of the GHG Protocol for the first time, less for ‘investments’. You can read more about how PDSE is engaging with its GHG emissions, and other
environmental impacts, in our annual ‘Environmental Report’

Our Focus and Aspirations
PDSE is currently developing an environmental management system in accordance with the requirements of BSI’s ISO14001 standard – the world’s most recognised standard for environmental management systems.
As part of this work we have identified our most significant environmental aspects and impacts, established an Environmental Policy and nine overarching Environmental Objectives, which map back to our aspects and impacts as well as developing and setting in play an Environmental Action Plan (EAP) – our comprehensive plan for delivering on our objectives.
Progress on our environmental objectives is reported each year in our annual Environmental Report.
What We've Been Up To Over The Last Few Months
Decontamination
Having transitioned our centralised decontamination facilities at our Devonport site from gas to electric we have been analysing the energy consumption of our autoclaves to help refine their operating approach – the refined operating approach adopted in 2024 will save around 20,000 kWh electricity per year.
LED retrofit
Since summer 2023 the Facilities Team have changed over 400 light fittings from fluorescent to LED at our Devonport and Derriford sites – the more efficient lights will realise an annual energy saving of around 38,000 kWh per year.
Electric Pool Vehicle
To help engage with the emissions associated with travel we have procured a battery electric pool van. The vehicle is set to arrive in September and the vehicle is anticipated to save around 1.8 tonnes CO2e per year.
EV Charging
In reflection of the high proportion of site users who access our sites by car in August we installed EV charging at our two directly operated car parks (Exeter and Derriford). The affordable to use chargers will help facilitate the transition to electric mobility for patients, staff and other site users and reduce emissions associated to travelling to our facilities.
Plant Optimisation
We are fortunate to have two 50kWp ground source heat pumps (GSHPs) at our Derriford site which deliver a share of the building’s heating demands and the majority of its cooling demands. To further the value of the GSHPs (and reduce the role of the accompanying gas boilers at the site) we are investing in improved sub-metering and BMS controls to be able to maximise the value of the existing GSHP system (and in time, help optimise the removal of the gas boilers from the site entirely).
Sustainable Procurement
Having previously worked to consolidate our clinical consumables orders (and thus reduce vehicle movements to our sites) this summer we have been working with our core suppliers to improve the data provided to us and, in turn, empower more Sustainable procurement. One area we are focusing on at present is our clinical wipes – we use over half a million clinical wipes per year and are currently trialling two plant-derived products as an alternative to our current plastic-based product.
Waste Services
We went out to tender for a new waste services provider in the summer of 2024 with the aspiration to deliver a more efficient, demand driven service and see waste sent to more local facilities for processing. The new contract is set to go live at the start of November and will also see offensive waste and food collections being introduced.
Community
In alignment with our interest in the communities we serve we held three community litter pick events for staff, friends and family near each of our sites in June 2024. In all 20 sacks of rubbish were collected – we are saving the sacks for a repeat event next year.
Biodiversity
In respect of the very worrying collapse in flying insect populations and building on PDSE’s previous engagement with the ‘No Mow May’ movement, we decided to set aside areas for ‘No Mow May’, ‘Let it Bloom June’ and ‘Knee High July’ this year, in areas where we are able to.
PV Generation
We are working to install PV generation at each of our directly operated sites in the next two years. The first site to be installed is Devonport – for which our planning permission to install a 92 kWp rooftop array was granted at the end of July. Once the system is up and running it will generate around 80,000 kWh per year of renewable electricity (at present, this will represent a saving of approximately 20 tonnes CO2e per year).
