What Suppliers Need to Know Ahead of 1 April 2027
Executive Summary
From 1 April 2027, NHS England will introduce enhanced Carbon Reduction Plan requirements for suppliers bidding into qualifying NHS procurements and, importantly, for suppliers participating in new NHS framework agreements.
This represents a significant development in NHS supplier carbon reporting. While many organisations have already produced Carbon Reduction Plans under the existing NHS and PPN 006 requirements, the 2027 requirements expand both the scale and depth of reporting expected from suppliers.
The most important changes are:
- A move from a UK minimum reporting boundary to a global organisational reporting boundary for the relevant reporting entity.
- An expansion from five prescribed Scope 3 categories to all relevant Scope 3 categories under the Greenhouse Gas Protocol Corporate Value Chain Standard.
- The expectation that suppliers can demonstrate a more mature, accurate and repeatable approach to annual carbon reporting..
For many suppliers, particularly those in pharmaceuticals, medical devices, diagnostics, consumables, healthcare technology, logistics and professional services, NHS frameworks are the primary route to market. This means the 2027 requirements should not be seen as relevant only to organisations bidding for large individual contracts. They are likely to become an important part of framework readiness, supplier assurance and future NHS market access.
Organisations should therefore be reviewing their existing Carbon Reduction Plans now to understand whether they are ready for the 2027 requirements.
- Background: NHS Net Zero and Supplier Reporting
The NHS has committed to achieving Net Zero for the emissions it controls directly by 2040, and for its wider carbon footprint, including supply chain emissions, by 2045.
The NHS supply chain represents a substantial proportion of the NHS carbon footprint. As a result, supplier carbon reporting has become an increasingly important part of NHS procurement and commercial assurance.
The NHS Supplier Roadmap has introduced requirements in stages:
- April 2022: Net Zero and Social Value introduced into NHS procurement, with a minimum 10% weighting.
- April 2023: Carbon Reduction Plans introduced for certain high-value contracts.
- April 2024: Carbon Reduction Plan requirements expanded proportionately across NHS procurements.
- April 2027: Enhanced NHS Carbon Reduction Plan requirements introduced.
- April 2028: Product-level requirements expected to follow.
The 2027 milestone should therefore be understood as part of a continuing direction of travel. Carbon reporting is no longer a standalone compliance exercise. It is becoming part of how suppliers demonstrate readiness, resilience and maturity in their approach to NHS procurement.
- Why the 2027 Requirements Matter
A common misconception is that the 2027 requirements will only affect suppliers bidding for individual NHS contracts valued at £5 million per annum or above.
This is only part of the picture.
From 1 April 2027, the enhanced NHS Carbon Reduction Plan requirements are expected to apply to:
- New high-value NHS contracts of £5 million per annum or above.
- All new NHS framework agreements run for NHS organisations.
This second point is particularly important.
Many suppliers do not sell to the NHS through a single large direct contract. Instead, they access NHS business through framework agreements, including those managed by NHS Supply Chain and other NHS purchasing organisations.
For suppliers whose NHS revenue depends on framework participation, the refresh or re-tender of a key framework after 1 April 2027 could become a critical point at which enhanced carbon reporting is assessed.
This means that organisations should be considering now whether their existing Carbon Reduction Plan would be sufficient if a major framework renewal or strategically important tender were launched after the go-live date.
- Current Position: What Suppliers Are Required to Report Today
Under the current NHS Carbon Reduction Plan requirements, aligned with PPN 006, suppliers are generally required to publish a Carbon Reduction Plan covering:
- Scope 1 emissions.
- Scope 2 emissions.
- A defined subset of Scope 3 emissions.
- A commitment to achieve Net Zero by 2050.
- Baseline year emissions.
- Current reporting year emissions.
- Carbon reduction initiatives.
- Board or director approval.
- Annual review and publication on the supplier’s website.
The five Scope 3 categories currently required are:
- Upstream transportation and distribution.
- Waste generated in operations
- Business travel.
- Employee commuting.
- Downstream transportation and distribution.
For many organisations, this has created a useful starting point. However, the 2027 requirements represent a significant expansion beyond the current model.
- What Changes from 1 April 2027?
The enhanced NHS Carbon Reduction Plan requirements introduce two major changes.
4.1 Global Reporting Boundary
The current requirements are based on a UK minimum reporting boundary.
From April 2027, suppliers will need to apply a global geographical boundary for the chosen reporting entity.
This means that organisations will need to consider emissions associated with their wider operations and value chain, regardless of where those emissions occur.
For example, a UK supplier may need to consider emissions linked to:
- Overseas manufacturing.
- International procurement.
- Imported raw materials.
- Global logistics.
- Overseas warehousing.
- International product distribution.
- Group-level activities where relevant to the reporting entity.
This is not simply a question of adding more data. It requires a careful review of the organisational and operational boundary being used for reporting.
For multinational healthcare suppliers, this may be one of the most significant changes.
4.2 Expansion to All Relevant Scope 3 Categories
Under the current requirements, suppliers report five defined Scope 3 categories.
From April 2027, suppliers will be expected to assess and report all relevant Scope 3 emissions in accordance with the Greenhouse Gas Protocol Corporate Value Chain Standard.
This means organisations will need to consider all 15 Scope 3 categories and determine which are relevant to their business.
The full Scope 3 categories are:
- Purchased goods and services.
- Capital goods.
- Fuel and energy-related activities not included in Scope 1 or Scope 2.
- Upstream transportation and distribution.
- Waste generated in operations.
- Business travel.
- Employee commuting.
- Upstream leased assets.
- Downstream transportation and distribution.
- Processing of sold products.
- Use of sold products.
- End-of-life treatment of sold products.
- Downstream leased assets.
- Franchises.
- Investments.
Not every category will apply to every organisation. However, suppliers will need to undertake a robust relevance assessment and clearly justify any exclusions.
For healthcare suppliers, categories such as purchased goods and services, capital goods, logistics, use of sold products and end-of-life treatment may become particularly important, depending on the nature of the products or services supplied.
- Why Purchased Goods and Services Will Be Important
For many suppliers, purchased goods and services is likely to be one of the most material Scope 3 categories.
This category captures emissions associated with the goods and services an organisation purchases to support its operations and deliver its products or services.
For pharmaceutical, medical device, diagnostics and healthcare product suppliers, this may include emissions linked to:
- Raw materials.
- Components.
- Packaging.
- Contract Manufacturing.
- Laboratory services.
- Professional services.
- Product inputs.
- Outsourced operations.
- Supplier networks.
This category is often complex because the data sits outside the immediate organisation and depends on supplier engagement, procurement records and carbon accounting methodology.
However, it is also one of the areas where a more accurate and mature approach can provide significant insight. Understanding purchased goods and services emissions can help organisations identify carbon hotspots, improve procurement decision-making and prepare for future NHS expectations.
- Data Quality, Accuracy and Methodology
NHS England recognises that suppliers may not have perfect data immediately and that recognised estimation methods can be used where primary data is not yet available.
However, suppliers should not view this as a reason to take a minimal approach.
A Carbon Reduction Plan is only as robust as the data, assumptions and methodology that sit behind it. Poorly structured carbon reporting can create problems in future years, particularly where organisations need to demonstrate progress, update annual emissions or respond to more detailed procurement questions.
For this reason, businesses should be seeking guidance from carbon reporting specialists who understand:
- The Greenhouse Gas Protocol.
- NHS Carbon Reduction Plan requirements.
- Scope 3 relevance assessments.
- Organisational and operational boundaries.
- Annual emissions reporting.
- Supplier data collection.
- Procurement assurance.
- Carbon reduction planning.
Spend-based analysis may have a role where better data is not yet available, but it should be used carefully and transparently. It should not be treated as the end goal. A stronger approach is to build a reporting framework that can improve over time, moving towards more accurate, activity-based and supplier-specific data wherever possible.
The objective should be to create a defensible baseline and a repeatable annual reporting process.
- Parent Company Reporting
The NHS guidance allows a parent company to report on behalf of a supplier in certain circumstances.
This can be helpful for organisations that are part of a wider group structure. However, the parent company Carbon Reduction Plan must still meet specific conditions.
In broad terms, the supplier engaging with the NHS must be appropriately covered by the parent company’s Carbon Reduction Plan, and the Net Zero commitment and environmental measures must apply to the NHS supplier entity.
This is an area where businesses should take particular care.
A global group sustainability report may not automatically satisfy the NHS Carbon Reduction Plan requirements. The document must be clear, accessible, relevant to the bidding entity and published appropriately.
Suppliers should therefore review whether their existing group-level reporting genuinely meets the NHS requirements or whether a separate or supplementary Carbon Reduction Plan is needed.
- Procurement Implications
Carbon Reduction Plans will continue to be assessed as part of the procurement process.
The assessment is expected to remain a pass/fail requirement, rather than a scored element that is compared between suppliers.
However, this does not reduce its importance.
A supplier that cannot demonstrate compliance with the relevant Carbon Reduction Plan requirements may be unable to progress through the procurement process.
For businesses with strategically important NHS tenders or framework renewals approaching after 1 April 2027, readiness should be treated as a commercial risk issue, not simply a sustainability task.
Suppliers should be asking:
- Which NHS frameworks are due to refresh after 1 April 2027?
- Which NHS tenders are strategically important to our business?
- Do we currently report all relevant Scope 3 categories?
- Have we reviewed our global reporting boundary?
- Can we justify excluded Scope 3 categories?
- Is our Carbon Reduction Plan board-approved and published?
- Can our annual reporting process be repeated reliably year after year?
- Evergreen and Supplier Readiness
The NHS Evergreen Sustainable Supplier Assessment will also play an important role in helping suppliers understand their maturity.
NHS England has indicated that:
- Evergreen Level 1 aligns with the current 2024 Carbon Reduction Plan requirements.
- Evergreen Level 2 aligns with the enhanced 2027 NHS Carbon Reduction Plan requirements.
While Evergreen does not guarantee that a Carbon Reduction Plan will pass in a procurement process, it provides a useful indication of whether a supplier is aligned to the relevant level of maturity.
Suppliers preparing for 2027 should therefore consider Evergreen readiness alongside their Carbon Reduction Plan review.
- Why Early Preparation Is Essential
The 2027 requirements go live on 1 April 2027.
Although a supplier may only need to demonstrate compliance when bidding for a relevant procurement or framework, waiting until a tender is live is unlikely to provide enough time to complete the work properly.
A robust Carbon Reduction Plan may require:
- Reviewing the reporting entity.
- Mapping organisational boundaries.
- Assessing all 15 Scope 3 categories.
- Identifying relevant and non-relevant categories.
- Collecting supplier and activity data.
- Reviewing international emissions sources.
- Establishing a baseline.
- Updating carbon reduction measures.
- Securing board or director approval.
- Publishing the updated Carbon Reduction Plan.
- Preparing for annual updates.
For some organisations, particularly multinational groups or suppliers with complex product portfolios, this may require significant coordination across procurement, finance, logistics, sustainability, quality, regulatory, operations and commercial teams.
Early preparation will reduce the risk of rushed reporting, weak assumptions and incomplete disclosures.
- Building the Foundation for Future Reporting
The 2027 requirements should not be viewed in isolation.
They are part of a broader shift towards more mature supplier carbon reporting across NHS procurement.
Organisations that establish robust reporting foundations now will be better placed to respond to future requirements, including product-level reporting, supply chain emissions scrutiny and increasing expectations around carbon reduction evidence.
A strong reporting framework should enable suppliers to:
- Report consistently year on year.
- Understand emissions hotspots.
- Improve data quality over time.
- Support procurement submissions.
- Evidence progress against Net Zero commitments.
- Identify practical carbon reduction opportunities.
- Engage suppliers more effectively.
- Prepare for future NHS and public sector requirements.
In contrast, organisations that rely on a one-off document or incomplete reporting process may find themselves needing to rebuild their approach each year.

- Key Takeaways
From 1 April 2027, NHS England’s enhanced Carbon Reduction Plan requirements will raise the standard for supplier carbon reporting.
The changes are significant because they are expected to apply not only to high-value NHS contracts, but also to all new NHS framework agreements.
For many suppliers, frameworks are the primary route to NHS business. This means the 2027 requirements could have a direct impact on future NHS market access.
The most important changes are:
- The move to a global reporting boundary.
- The expansion to all relevant Scope 3 categories.
- The need for stronger annual carbon reporting processes.
- The importance of accurate, defensible and repeatable data.
- The alignment of Evergreen Level 2 with the enhanced 2027 requirements.
Suppliers should begin reviewing their position now.
A well-prepared organisation will not only be ready for April 2027 but will also have a stronger foundation for future carbon reporting, procurement assurance and long-term decarbonisation.
