NHS Trusts across England are making measurable progress towards net-zero targets, five years after NHS England committed to reaching net-zero for direct emissions by 2040.
However, significant gaps remain in planning, measurement, and energy sourcing, according to new research from Schneider Electric.
The study, based on Freedom of Information responses from 66 Trusts, found:
- 21% of Trusts do not have a clear roadmap to meet net-zero targets, down from 31% in 2024.
- 21% are not measuring their carbon footprint, compared with 29% last year.
- 26% of Trusts still source more than 90% of their energy from fossil fuels.
NHS Trusts were required to submit updated, board-approved Green Plans to NHS England by July 2025.
Schneider Electric’s research suggests that some Trusts still lack clear roadmaps and robust measurement to meet net-zero targets.
Technology adoption and digitalisation are increasing across the NHS estate:
- 64% of Trusts are using systems to monitor and optimise energy use, up from 48% in 2024.
- 64% have upgraded building systems, while 33% have digitised electrical infrastructure to improve efficiency.
- 30% of Trusts have introduced circular practices, such as refurbishing or redistributing medical equipment, up from 19% in 2024.
- 9% have introduced training programmes to encourage sustainable behaviours.
Funding for decarbonisation projects has risen, with 89% of Trusts receiving support, compared with 67% in 2024.
Investments include:
- 64% installing renewable energy sources, such as solar panels (up from 16% last year).
- 53% upgrading heating, ventilation, and air conditioning (HVAC) systems.
- 68% installing energy-efficient technologies, including LED lighting.
“Trusts are making progress on net-zero, but energy usage and costs remain challenges. Technology and renewables provide opportunities to improve efficiency and reduce emissions,” said Alice Williams, VP Digital Energy UK&I at Schneider Electric.
The findings highlight both measurable progress and ongoing structural gaps in the NHS’s approach to sustainability, underscoring the need for clear roadmaps, continued investment, and wider adoption of low-carbon solutions to meet the 2040 target.
