Practical sustainability support for NHS suppliers

GB Sustainability helps smaller businesses turn sustainability requirements into clear evidence, practical actions and usable submissions. Our work with NHS suppliers connects Evergreen with the evidence behind it, including carbon footprints, Carbon Reduction Plans and wider sustainability requirements.

Direct, experienced support

You work directly with Gareth from the first conversation through to delivery, so the advice stays consistent and grounded in your business.

What is the NHS Evergreen Sustainable Supplier Assessment?

Evergreen is NHS England's sustainability self-assessment for suppliers. It is completed through Atamis and gives suppliers a maturity level against current NHS sustainability priorities.

It gives the NHS a consistent view of supplier progress and reduces repeated requests for the same sustainability information. Suppliers can complete Evergreen if they already supply, or plan to supply, NHS England, an integrated care board or an NHS trust in England.

Evergreen at a glance

  • Suppliers complete the assessment through Atamis.
  • NHS England recommends completing it annually. The resulting maturity score is valid for 12 months.
  • Significant updates can be made during the year.

A supplier self-assessment

GB Sustainability can help you interpret the requirements, review evidence and support completion. We do not award an official level or guarantee how an NHS buyer will use your assessment.

When might your business need Evergreen?

The answer depends on how you supply the NHS. Evergreen is not used in exactly the same way across every procurement route, so start with the tender, framework or buyer requirement in front of you.

NHS Supply Chain tender

From 6 April 2026, NHS Supply Chain requires suppliers submitting tenders to have achieved Evergreen Level 1 at tender close.

NHS England Medicines tender

Suppliers tendering for contracts or frameworks administered by NHS England Medicines Value and Access need a valid Evergreen assessment at the point of submission.

Annual reassessment

Your Evergreen maturity score is valid for 12 months, so an existing assessment may need refreshing before a new opportunity.

Changed evidence or requirements

A new Carbon Reduction Plan, updated emissions footprint, organisational change or revised maturity criteria may alter what your existing evidence supports.

Preparing for April 2027

New NHS Carbon Reduction Plan requirements begin from 1 April 2027 and expand carbon reporting for many higher-value procurements and new frameworks.

What do Evergreen Levels 1–4 require?

Evergreen uses four maturity levels. They build from a current Carbon Reduction Plan and core emissions reporting towards broader global carbon coverage, independently validated targets and stronger modern-slavery evidence.

Level 1

Build the NHS baseline

A current, published Procurement Policy Note-aligned Carbon Reduction Plan; a UK Net Zero commitment by 2050 or earlier; Scope 1, Scope 2 and the required subset of Scope 3 emissions; board-level approval; and Greenhouse Gas Protocol-aligned reporting.

Level 2

Broaden the carbon boundary

Scope 1, Scope 2 and all relevant Scope 3 emissions across the global business boundary, with a 2050 or earlier Net Zero target and the same core publication, approval and reporting controls.

Level 3

Strengthen targets and evidence

A 2045 (or earlier) Net Zero target, independent target validation and GHG emissions verification for the reporting entity, plus a public Modern Slavery Statement and a completed Modern Slavery Assessment Tool.

Level 4

Extend across the global organisation

Independently validated 2045 Net Zero targets and verified GHG emissions for the reporting entity and global parent (where relevant), higher-performer transparency reporting (e.g. B-Corp, CDP or EcoVadis), and active supply-chain mapping or investigation & mitigation of modern-slavery risks.

Use the levels as a maturity map, not a substitute for the assessment

This is a practical summary of the April 2026 criteria, not the full questionnaire. Current NHS guidance and the specific procurement documents should be checked before relying on a level for a live tender.

Build only what is missing

We need help creating or improving evidence

Choose only the modules you need—from carbon footprints and Carbon Reduction Plans to modern-slavery and supply-chain risk work.

Discuss the evidence you need

A clear route from requirement to the next action

1. Clarify the trigger

Confirm the procurement route, deadline, target level and any previous Evergreen result before doing unnecessary work.

2. Check readiness and evidence

Use the free check independently, or choose an Evidence Review when the documents themselves need checking.

3. Diagnose an unsuccessful result

Where needed, diagnose the feedback, answers and evidence mapping before rebuilding documents.

4. Close the agreed gaps

Create or update only the carbon, CRP, modern-slavery, transparency or supply-chain evidence genuinely needed.

5. Complete or resubmit

Map the evidence to the relevant questions and complete or resubmit in Atamis, independently or with support.

6. Maintain or progress

Keep evidence current for reassessment and compare the work required for a higher level or future requirements.

Healthcare sustainability support in practice

Smiling woman with short hair, wearing glasses and a black blazer against a grey background.

GB Sustainability has supported Ferndale Pharmaceuticals with Evergreen work on several occasions alongside wider carbon and sustainability work.

That experience matters because Evergreen draws on evidence such as Carbon Reduction Plans, emissions data, governance and modern-slavery information. Practical support needs to connect the assessment with the underlying documents.

Our approach is to review what already exists first, preserve evidence that is still useful and focus effort on gaps that genuinely affect the requirement.

"As a pharmaceutical provider, we are facing increasing expectations from both clients and legislation. Working with GB us the structure, guidance and confidence to really move things forward.

"This has strengthened our ability to meet the sustainability requirements increasingly expected within the NHS and larger client tender processes, putting us in a much stronger position when bidding for new opportunities."

Support for wider NHS supplier sustainability requirements

GB Sustainability can also help with the Carbon Reduction Plans, carbon footprints and modern-slavery evidence that NHS tenders and frameworks may require. We start with the procurement route and identify only the gaps you need to close.
