UCLH's net zero strategy and plan
Climate change is the biggest global health threat of the 21st century. However, there is no doubt that we can all play our part in rising to this challenge.
At UCLH we published an updated version of our Green Plan, Care Without Carbon in July 2025, which builds upon our net zero strategy first launched in 2023. The plan reflects our ambition to create an environment where sustainability is embedded in everything we do, for the wellbeing of our patients, our staff, and our wider community.
Climate change is already affecting health outcomes, and these impacts make it increasingly urgent to reduce our own carbon footprint.
Care Without Carbon was developed through a collaborative, data-led approach involving colleagues from across UCLH and our partners. It sets out clear net zero goals and actions across nine key themes, including workforce, clinical transformation, digital innovation, and supply chain.
The plan recognises that progress must be made against a challenging financial backdrop. But there is a triple win to delivering our plan. We can lower carbon emissions, improve patient outcomes, and save taxpayers money.

UCLH declares a climate and health emergency
Since UCLH declared a climate and health emergency publicly in 2020, we have already made significant progress, including:
- installing low-energy lights
- switching to sustainable electricity and recycled paper
- reducing patient journeys by up to 45 per cent
- reducing the use of the most harmful anaesthetic gas by up to 100 per cent
- encouraging staff to take part in climate action schemes
We are dedicated to treating and supporting our patients and staff within the constraints of our natural resources, increasing our readiness for changing times and climate, and strengthening our links with the local community.
We aim to embed sustainable development principles in every facet of our activities. Read more about our progress on our other climate action web pages.
In line with the NHS' own carbon reduction target of achieving net zero emissions by 2040, UCLH issued its Green Plan in 2020 and Net Zero strategy in 2023. Having declared a Climate and Health Emergency in 2021, we are now aiming to go further and achieve this target by 2031. The UCLH Sustainability Programme Board is responsible to the UCLH Board for meeting these challenges. The group consists of senior managers and clinicians from pharmacy, radiography, procurement, information systems, and estates and facilities management. Its work is constantly evolving, and it remains responsive to new challenges.
Working with the NHS
We are working with colleagues across the NHS to reduce the impact and cost of energy, waste, water and transport. As a member of the Shelford Group of NHS trusts, we are collectively working towards sustainable procurement.
We are working with colleagues across North Central London to collaborate, share ideas, and problem solve. We are the ICB’s lead provider in two key areas: reusable PPE and sustainable medicines.
Working with the community
We are an advisory board member of the Camden Climate Change Alliance. We are working with local businesses, public sector organisations, and local Business Improvement Districts to minimise adverse effects on biodiversity from our necessary operations and to ensure that all members of staff are aware of their responsibilities towards protecting biodiversity. We will continue with this collaboration to achieve common goals.
Our climate action approach is defined by policies for sustainable development, carbon, and waste management that are endorsed by the UCLH Board. These integrate the latest requirements and guidance from the Greener NHS.
In line with the NHS Standard Contract, the UCLH Net zero strategy: “Critical care for our climate”, outlines our strategy towards a 'net zero' UCLH. It takes into consideration the NHS Long Term Plan's commitments, together with the NHS' own ambition to achieve environmental sustainability.
