NHS Net-Zero Supplier Roadmap: carbon reporting rules

Summary

The NHS England Net-Zero Supplier Roadmap is a phased procurement framework requiring suppliers to align with the NHS net-zero ambition. It introduces progressively stronger supplier requirements on carbon reduction plans, emissions reporting, net zero commitments, sustainability assessment, and, from 2028, product-level carbon footprinting. The roadmap applies through NHS procurement processes and is designed to reduce emissions from the NHS supply chain, which is one of the largest sources of healthcare-related carbon impact.

Details

Jurisdictions

The United Kingdom

Mandatory for

The roadmap becomes mandatory when a supplier is participating in relevant NHS procurement processes. Requirements can apply through tender conditions, framework rules, procurement policy and contract eligibility.

Mandatory elements can include:

Net-zero and social value evaluation.

Carbon Reduction Plan publication.

Net-zero commitment.

Evergreen Sustainable Supplier Assessment where required.

Scope 1 and Scope 2 emissions reporting.

Required Scope 3 categories.

Global Scope 1, 2 and 3 reporting from April 2027.

Product-level carbon footprinting from April 2028 when implemented.

Progress reporting from 2030.

For NHS procurement, this is a market access issue. Suppliers may be unable to bid, qualify or remain competitive if they cannot meet the relevant roadmap stage.

Exemptions

NHS England states that it will account for specific barriers faced by some suppliers and that support will be available for SMEs and voluntary, community and social enterprises at each stage of the roadmap.

Practical variation may depend on:

Contract value.

Supplier size.

Procurement route.

Whether the buyer is NHS England, NHS Supply Chain or another NHS body.

Whether the tender is for medicines, goods, services or works.

SME or VCSE status.

Difficulty gathering emissions data.

Whether requirements are applied proportionately.

Whether a framework has additional conditions.

However, proportionality should not be read as exemption from the direction of travel. The roadmap clearly moves toward broader emissions reporting and stronger supplier requirements over time.

Practical updates. Once per week.

What’s Required

From April 2022, all NHS procurements include a minimum 10% net zero and social value weighting. This means climate and social value considerations are not optional add-ons, but part of how bids are evaluated.

For suppliers, this can include evidence on:

Carbon reduction.
Environmental management.
Social value delivery.
Health inequalities.
Local employment.
Supply-chain resilience.
Waste reduction.
Sustainable transport.
Low-carbon service delivery.

This milestone builds on UK public procurement policy and adapts it to healthcare-specific outcomes.

2. Carbon Reduction Plan for major contracts

From April 2023, suppliers bidding for all new NHS contracts above £5 million per annum were required to publish a Carbon Reduction Plan, or CRP, covering UK Scope 1 and Scope 2 emissions and a subset of Scope 3 emissions as a minimum. This aligned with UK government procurement policy requirements.

A CRP should usually include:

Baseline emissions.
Current emissions.
Scope 1 emissions.
Scope 2 emissions.
Required Scope 3 categories.
Emissions reduction targets.
Net zero commitment.
Carbon reduction measures.
Publication date.
Board or senior approval.
Public availability.

This requirement is a procurement gate: a weak or missing CRP can affect eligibility for NHS contracts.

3. Extension of Carbon Reduction Plan requirements to all new procurements

From April 2024, NHS England proportionately extended Carbon Reduction Plan requirements to cover all new procurements. NHS England’s supplier guidance states that the April 2024 milestone expands CRP and net zero commitment requirements beyond the earlier £5 million threshold.

This means smaller contracts and a wider range of suppliers are brought into the net zero procurement process, although requirements may be applied proportionately.

4. Evergreen Sustainable Supplier Assessment

The Evergreen Sustainable Supplier Assessment is NHS England’s online tool for suppliers to share sustainability information with the NHS and understand how they align with NHS net zero and sustainability ambitions. NHS England describes Evergreen as a self-assessment and reporting tool that provides a single route for sustainability data sharing between suppliers and NHS decision-makers.

Evergreen is relevant because it helps suppliers demonstrate maturity across:

Carbon reduction.
Sustainability governance.
Emissions measurement.
Net zero targets.
Waste and resource use.
Social value.
Modern slavery and wider responsible procurement.
Progress against NHS roadmap expectations.

NHS Supply Chain states that from April 2026, all suppliers are required to complete an Evergreen Supplier Assessment and achieve Level 1 as a minimum.

5. Medicines tenders and Evergreen requirements

NHS England states that suppliers intending to tender for a contract or framework administered by NHS England Medicines Value and Access require a valid Evergreen Sustainable Supplier Assessment and a compliant Carbon Reduction Plan at the point of submission. These requirements apply from January 2024 and April 2024, respectively.

This is important for pharmaceutical, medical technology and healthcare product suppliers because sustainability evidence is increasingly embedded into tender readiness.

6. April 2027 global emissions and full Scope 1, 2 and 3 requirements

From April 2027, NHS England will introduce requirements for suppliers to publicly report targets, emissions and publish a Carbon Reduction Plan for all relevant global Scope 1, Scope 2 and Scope 3 emissions, aligned to the NHS net zero target. NHS England published April 2027 milestone guidance in June 2026 to clarify supplier and buyer expectations.

This is a major shift from UK operational emissions and selected Scope 3 categories to broader global value-chain emissions.

Suppliers should prepare to report:

Global Scope 1 emissions.
Global Scope 2 emissions.
Relevant global Scope 3 emissions.
Climate targets.
Carbon Reduction Plan.
Alignment with NHS net zero ambition.
Methodologies, assumptions and exclusions.
Progress against previous targets.

The April 2027 milestone is one of the most important future compliance gates in the roadmap.

7. April 2028 product-level carbon footprinting

From April 2028, new requirements are expected for carbon footprinting of individual products supplied to the NHS. NHS England says it will work with suppliers and regulators to determine scope and methodology.

This will matter for:

Medical devices.
Pharmaceuticals.
Consumables.
PPE.
Diagnostics.
Food and catering.
Facilities products.
ICT hardware.
Construction products.
Logistics services.

Product-level footprinting is likely to move supplier requirements from corporate-level reporting toward product-specific procurement decisions.

8. 2030 contract qualification milestone

NHS England’s supplier page states that from 2030, suppliers will only be able to qualify for NHS contracts if they can demonstrate progress through published progress reports and continued carbon emissions reporting.

This makes the roadmap a long-term market access pathway. Suppliers that do not build emissions measurement and transition planning capacity may lose NHS procurement eligibility over time.

Important Deadlines

April 2022: net zero and social value weighting

All NHS procurements include a minimum 10% net zero and social value weighting.

April 2023: CRP required for contracts above £5 million per annum

For all new contracts above £5 million per year, suppliers must publish a Carbon Reduction Plan covering UK Scope 1 and Scope 2 emissions and selected Scope 3 categories as a minimum.

January 2024: Evergreen for NHS England medicines tenders

NHS England medicines tenders carried out by Medicines Value and Access require Evergreen submission from January 2024.

April 2024: CRP requirements extended to all new procurements

NHS England proportionately extended CRP and net zero commitment requirements to all new procurements.

April 2026: Evergreen minimum Level 1 for NHS Supply Chain suppliers

NHS Supply Chain states that all suppliers are required to complete an Evergreen Supplier Assessment and achieve Level 1 as a minimum from April 2026.

April 2027: global Scope 1, 2 and 3 CRP requirements

Suppliers will be required to publicly report targets, emissions and publish a Carbon Reduction Plan for all relevant global Scope 1, 2 and 3 emissions aligned with the NHS net zero target. NHS England published detailed milestone guidance in June 2026.

April 2028: product-level carbon footprinting

NHS England plans to introduce new requirements for carbon footprinting of individual products supplied to the NHS.

2030: qualification based on progress reporting

From 2030, suppliers will only be able to qualify for NHS contracts if they can demonstrate progress through published progress reports and continued carbon emissions reporting.

Current Status

The NHS England Net-Zero Supplier Roadmap is active and being implemented in stages.

Current status:

The roadmap was adopted as statutory guidance in 2022, according to NHS England’s April 2027 market sounding findings.
The 2022 net zero and social value procurement weighting is in place.
The 2023 CRP requirement for contracts above £5 million per annum has been implemented.
The 2024 extension of CRP requirements to all new procurements has been implemented.
Evergreen is active as NHS England’s sustainability self-assessment and reporting tool.
NHS England published April 2027 milestone requirements in June 2026.
April 2028 product-level footprinting requirements are still to be finalised.
2030 qualification requirements are a future procurement milestone.

The roadmap is not a general environmental law applying to every UK company. It is a procurement-linked supplier requirement for organisations seeking to supply goods, services or works to the NHS.

Penalties for Non-Compliance

The roadmap is enforced mainly through procurement and contract mechanisms rather than through environmental fines.

Possible consequences include:

1. Bid rejection or exclusion

A supplier may be unable to proceed in a tender if it fails to provide a compliant Carbon Reduction Plan, net zero commitment or required sustainability assessment.

2. Lower evaluation scores

Where net zero and social value are weighted in procurement, weak climate evidence can reduce competitiveness.

3. Framework ineligibility

Suppliers may fail to qualify for NHS Supply Chain frameworks or NHS England medicines tenders if they do not meet Evergreen or CRP requirements.

4. Contractual consequences

Failure to maintain required reporting, progress evidence or sustainability commitments may create contractual issues, depending on tender terms.

5. Market access restriction from 2030

From 2030, suppliers will only be able to qualify for NHS contracts if they demonstrate progress through published progress reports and continued emissions reporting.

6. Reputational damage

Healthcare suppliers may face reputational risk if they claim NHS net zero alignment without credible emissions data, transition planning or published progress.

7. Customer and investor scrutiny

Suppliers to the NHS may face wider scrutiny from public buyers, investors, customers and regulators if their climate claims are inconsistent with procurement submissions.

Examples of Known Violations / Failure Modes

Typical violations and failure modes include:

Submitting no Carbon Reduction Plan where one is required.
Publishing a CRP that is not publicly accessible.
Covering only Scope 1 and 2 emissions when relevant Scope 3 categories are required.
Using incomplete or outdated emissions data.
Failing to include a clear net zero commitment.
Publishing targets without a baseline year or methodology.
Treating the CRP as a generic sustainability statement rather than a procurement compliance document.
Failing to obtain senior approval for the CRP.
Omitting emissions reduction measures.
Using inconsistent data between CRP, annual report, ESG report and tender submission.
Submitting an Evergreen assessment only after tender deadlines.
Claiming NHS net zero alignment without evidence of progress.
Ignoring April 2027 global Scope 1, 2 and 3 requirements.
Failing to prepare for 2028 product-level carbon footprinting.
Providing supplier emissions data that cannot be verified or reconciled.
