Sustainability is no longer a ‘nice to have’ for the NHS. From net zero commitments to the undeniable link between environmental and human health, greener healthcare is now a statutory duty and an urgent one at that.
But there’s one common misconception still holding many Trusts back:
“We can’t communicate about sustainability internally — it’s a GDPR risk.”
We hear this all the time. Whether it’s ideas for staff engagement, patient-facing campaigns, or wider green behaviour initiatives, GDPR is often cited as the reason for doing less.
The truth? GDPR isn’t the barrier. Misunderstanding it is.

GDPR Doesn’t Block Sustainability. It Sets the Guardrails
The UK GDPR and Data Protection Act are designed to ensure that communication is fair, transparent, and respectful. They don’t prevent NHS organisations from sharing messages that support statutory environmental goals they just shape how it’s done.
In fact, when it comes to sustainability comms, NHS Trusts are on solid legal ground.
Sustainability in Healthcare Is a Statutory Duty
Two key pieces of legislation make this clear:
- The Climate Change Act 2008
Legally binding targets require all sectors, including the NHS, to reduce carbon emissions. - The Health and Care Act 2022
Introduces a formal duty for NHS organisations to contribute to environmental sustainability as part of their care delivery.
This means that sustainability isn’t a side project. It’s a core operational responsibility and one that justifies appropriate internal and external engagement.
Finding The Right Legal Basis For GDPR Allowance
Most sustainability communications in the NHS will fall under one of two lawful bases:
- Public Task (Article 6(1)(e))
Used when the communication relates directly to your official functions, including environmental duties under the Health and Care Act.
- Legitimate Interests (Article 6(1)(f))
Applies when promoting sustainability aligns with broader organisational goals (e.g. energy reduction, Greener NHS strategy), and the communication is balanced with individual rights.
In both cases, consent is not required as long as communications are:
- Clearly linked to your statutory responsibilities.
- Transparent and relevant.
- Easy to opt out of if appropriate (particularly for non-critical messages).
The Real Risk? Missing the Moment
Every day that sustainability comms are delayed by GDPR concerns is a missed opportunity:
- To drive frontline energy and waste reductions.
- To embed climate-conscious behaviours across clinical and operational teams.
- To engage patients and staff in improving the spaces they work and recover in.
The NHS has one of the largest carbon footprints in the public sector. It also has one of the largest opportunities to lead change but this can only happen if everyone has the opportunity to be involved.
