PPN 006 Compliance in Healthcare: What NHS Commissioners Need from Suppliers - and How Gray Healthcare Delivers

As the NHS continues its transition toward a more sustainable future, environmental performance is no longer a secondary consideration in commissioning decisions. It is now a core requirement.

As part of the Greener NHS programme, the National Health Service has committed to achieving net zero, with targets of 2040 for directly controlled emissions, and 2045 for those generated across its broader supply chain.

For NHS suppliers, this shift has fundamentally changed the landscape of procurement.

Today, organisations bidding for NHS contracts must demonstrate not only clinical quality and value for money, but also a clear and credible Carbon Reduction Plan NHS supplier framework, aligned with Procurement Policy Note 06/21 (PPN 006).

In this blog, we explore what PPN 006 compliance in healthcare means in practice, and how we, at Gray Healthcare, are already meeting these expectations through a transparent and effective Carbon Reduction Plan.

Why PPN 006 Compliance Matters in NHS Procurement

The introduction of PPN 006 by the UK government marked a significant step in embedding sustainability into public sector contracts.

Under this procurement policy note, any organisation bidding for contracts above a specified contract value must submit a compliant Carbon Reduction Plan (CRP). This ensures that all suppliers actively contribute to the NHS’s wider net zero commitment.

For NHS procurements, this means commissioners must now assess:

• A supplier’s current carbon footprint
• Their baseline and emissions data
• Their strategy for reducing carbon emissions
• Their supplier roadmap of their commitment to achieving net zero
• Their ability to report their organisation’s emissions in line with Greenhouse Gas (GHG) Protocol standards

Importantly, this is not simply a compliance exercise. It is about ensuring that every supplier in the NHS supply chain contributes meaningfully to achieving net zero carbon emissions.

For Integrated Care Boards (ICBs), local authorities and commissioning teams, this creates a new layer of due diligence: identifying providers who are not only compliant, but credible.

What PPN 006 Compliance Healthcare Requires in Practice

At its core, PPN 006 compliance healthcare requires organisations to produce a full Carbon Reduction Plan that meets specific requirements.

A compliant plan must include:

1. Baseline Emissions

Suppliers must establish a baseline emissions footprint for a defined reporting period, typically covering:

• Scope 1 (Direct Emissions)
• Scope 2 (Energy-Related Emissions)
• Relevant Scope 3 emissions, including:
  • Business travel
  • Employee commuting
  • Waste generated in operations
  • Upstream transportation and distribution

These emissions are measured in carbon dioxide equivalent (CO2e) using recognised reporting standards, including the Greenhouse Gas Protocol.

2. Net Zero Commitment

Organisations must demonstrate a clear commitment to net zero, aligned with the Climate Change Act and the UK’s legally binding target of net zero by 2050.

This includes:

• A defined net zero target
• Evidence of senior leadership accountability
• Clear governance structures (e.g. board or equivalent management body sign-off)

3. Carbon Reduction Targets and Roadmap

Suppliers must outline:

• Measurable carbon reduction targets
• A structured supplier roadmap
• Future roadmap milestones demonstrating progress toward achieving net zero

4. Environmental Management Measures

A credible plan must include practical steps to reduce emissions, such as:

• Energy efficiency measures
• Reduction in waste generated
• Sustainable transport initiatives
• Supply chain engagement

5. Transparent Emissions Reporting

Finally, organisations must ensure robust carbon reporting, including:

• Clear methodology aligned with GHG protocol
• Transparent assumptions
• Regular updates to improve data accuracy

From Compliance to Credibility: What Commissioners Should Look For

While many organisations can produce a Carbon Reduction Plan (CRP), not all plans are equal.

For commissioners, the key question is not simply whether a supplier is compliant – but whether their approach is:

• Proportionate to their service model
• Embedded within operations
• Supported by real data
• Deliverable over time

In practice, this means looking beyond the document to assess:

• How emissions are generated within the organisation
• Whether reduction measures are realistic
• Whether sustainability is integrated into service delivery

How Gray Healthcare Meets PPN 006 Requirements

At Gray Healthcare, our Carbon Reduction Plan has been designed to demonstrate how we meet – and in many areas exceed – PPN 006 compliance healthcare requirements, supporting sustainable NHS procurement.

A Transparent Baseline and Reporting Framework

Gray Healthcare’s baseline emissions for the reporting period (1 April 2024 – 31 March 2025) total:

• Total Emissions: 325.93 tCO2e
• Scope 1: 0.00 tCO2e
• Scope 2: 8.54 tCO2e
• Scope 3: 317.39 tCO2e

These emissions have been calculated and reported in line with recognised standards, including the GHG Protocol Corporate Accounting and Reporting Standard, ensuring transparency and consistency in our carbon reporting.

A Realistic Understanding of Scope 3 Emissions

Our Carbon Reduction Plan highlights that the majority of our emissions arise from Scope 3 sources, particularly:

• Employee commuting (258.30 tCO₂e)
• Business travel and transportation activities

This is a significant insight.

It demonstrates that our operational carbon footprint – the direct delivery of care – remains relatively low, with the majority of emissions linked to workforce logistics rather than the provision of care itself.

For commissioners, this distinction is significant. It highlights that delivering complex care within community-based supported living models can be aligned with sustainable healthcare procurement, while still meeting the needs of individuals with complex presentations.

A Clear Net Zero Commitment

At Gray Healthcare, we are committed to achieving net zero carbon emissions by 2050, in line with central government targets and the wider ambitions of the NHS net zero strategy.

This commitment is underpinned by:

• Board-level sign-off and senior leadership accountability
• Clearly defined carbon reduction targets
• Ongoing improvement in the quality and accuracy of our emissions data

Practical Environmental Management Measures

Our Carbon Reduction Plan sets out a range of environmental management measures designed to reduce our carbon footprint in a proportionate and operationally relevant way.

These include:

• Transitioning to renewable electricity where contracts allow
• Reducing PPE waste and single-use plastics through improved procurement and usage practices
• Promoting low-carbon commuting through staff initiatives
• Investing in electric fleet vehicles to reduce emissions from business travel
• Maintaining hybrid and flexible working arrangements to minimise unnecessary travel

These measures reflect a practical and sustainable approach, aligned with how we deliver services as a specialist provider of community-based care.

A Structured Reduction Trajectory

We have established a clear and measurable pathway toward achieving net zero, including:

• A 50% reduction in emissions by 2030
• Achieving net zero emissions by 2050

This structured trajectory provides commissioners with a clear confidence that our approach is both compliant and deliverable with PPN 006 requirements, but also deliverable and aligned with long-term NHS net zero targets.

Why This Matters for NHS Commissioners

For NHS organisations, selecting suppliers who meet supplier sustainability requirements is not simply about compliance.

It is about ensuring that:

• Services contribute to NHS net zero targets
• Environmental impact is reduced across the supply chain
• Procurement decisions support long-term sustainability

We believe that Gray Healthcare’s model offers several advantages in this context.

1. Low Direct Emissions from Service Delivery

With zero Scope 1 emissions and minimal Scope 2 emissions, the delivery of care itself generates relatively low carbon emissions.

This is particularly relevant for commissioners seeking sustainable healthcare procurement solutions.

2. Community-Based Care Reduces Environmental Impact

By supporting individuals in their own homes rather than inpatient settings, our organisation aligns with broader NHS goals:

• Reducing reliance on high-energy hospital environments
• Supporting local, community-based care
• Minimising environmental impact of large-scale facilities

3. Workforce-Focused Carbon Strategy

At Gray Healthcare, the concentration of our emissions within employee commuting presents a clear opportunity:

• Targeted reduction initiatives can deliver meaningful impact
• Changes can be implemented without compromising care quality

4. Procurement-Ready Sustainability

We have developed our Carbon Reduction Plan to ensure we are procurement-ready and aligned with NHS expectations. Our approach is:

• Fully compliant with PPN 006 requirements
• Supported by robust and transparent emissions reporting
• Signed off by senior leadership, ensuring clear accountability
• Built on recognised reporting standards, including the GHG Protocol

This ensures we can confidently participate in framework agreements, support supplier bidding processes, and demonstrate compliance with Evergreen Sustainable Supplier Assessment requirements.

Supporting the NHS’s Long Term Net Zero Ambitions

The NHS has committed to becoming the world’s first net zero national health system.

Achieving this ambition depends not only on internal change, but on the actions of its suppliers.

Every NHS supplier plays a role in:

• Reducing greenhouse gas emissions
• Improving environmental performance
• Supporting sustainable care delivery

For providers of complex care, this presents both a responsibility and an opportunity.

By aligning with PPN 006 compliance healthcare, organisations can:

• Strengthen their position in procurement processes
• Demonstrate long-term sustainability
• Contribute meaningfully to achieving net zero

Procurement, Sustainability and the Future of Care

The shift toward sustainable healthcare procurement is not a future consideration – it is already shaping commissioning decisions across the NHS.

Through PPN 006, the UK government has established clear expectations: suppliers must understand, measure and actively reduce their carbon footprint.

For commissioners, the focus is now on identifying providers who can deliver:

• High-quality care
• Long-term sustainability
• Credible and compliant carbon reduction strategies

At Gray Healthcare, we have developed an approach that demonstrates how sustainability and high-quality care can be delivered together. By combining a clinically informed model with a transparent and compliant Carbon Reduction Plan that meets PPN 006 carbon reduction plan requirements, we are well positioned to support NHS net zero targets while continuing to deliver effective community-based care.
