What is the NHS Carbon Reduction Plan? A Quick Guide for Potential Suppliers

If you’re a potential NHS supplier, there’s a good chance you’ve heard of the NHS Carbon Reduction Plan - a requirement for suppliers to calculate and share information about their greenhouse gas emissions.

It’s important to understand what the CRP is all about if you want to stay competitive in the procurement process and make sure your organisation is contributing to a sustainable healthcare system.

There are a few key things to be aware of here. In this article, we’ll show you what the CRP is all about, what’s required of you, and the steps you should follow to make sure you comply with all the requirements.

What is the NHS Carbon Reduction Plan?

The NHS Carbon Reduction Plan is based on the UK government’s wider goal to reach Net Zero carbon emissions by 2050. In simple terms, by this date the UK aims to balance any greenhouse gases it still emits with an equal amount removed from the atmosphere.

For the NHS and businesses that work with it (like yours), there are two key targets to be aware of:

For the emissions the NHS directly controls, the goal is to reach Net Zero by 2040, and reach an 80% reduction by 2028 to 2032

For emissions the NHS can influence (but not directly control) the goal is to reach Net Zero by 2045 and an 80% reduction by 2036 to 2039

‍

These goals depend on the active participation of NHS stakeholders, including suppliers.

Early progress was encouraging. In its 2020 report, Delivering a Net Zero National Health Service, the NHS said:

“the estimated 62% reduction in emissions significantly exceeds the 37% requirement for 2020 outlined in the Climate Change Act. The wider scope of the NHS Carbon Footprint Plus has also delivered a meaningful improvement on the 1990 baseline, with an estimated reduction of 26% by 2020”

What’s required in the NHS Carbon Reduction Plan?

So, what’s your role in all this?

Potential and existing suppliers of the NHS must be able to measure and report on their carbon footprints effectively. You’ll do this through a Carbon Reduction Plan, or CRP, which should be published on your website.

Basically, the purpose of the CRP is to help you measure and share your carbon footprint and clearly show the steps you’ll take to reduce your emissions. It’s a way to show everyone that you’re committed to achieving Net Zero and have a concrete plan to get there.

Since the NHS is making sustainability a central part of its procurement process, it’s important for suppliers to adopt sustainable practices when it comes to sourcing materials, manufacturing, and logistics. You’ll need to be conscious about minimising environmental impact throughout the lifecycle of your products and services.

The NHS Carbon Reduction Plan template

To make it easier for suppliers to create and publish a CRP, the government publishes a PPN 006 Carbon Reduction Plan template, which the NHS asks suppliers to follow and which you can find here.

The most difficult part of this process, for suppliers like you, is understanding what your emissions are and how to accurately measure them. This is where Seedling’s carbon accounting platform can help. We help existing and future NHS suppliers compile all the necessary emissions data and share it in the right way.

Who needs to submit a CRP?

Since September 2021, central government departments have been required to include a Carbon Reduction Plan as a selection criterion when buying goods/services when the following criteria are met:

Contract value exceeds £5m a year (including VAT since February 2025, when PPN 06/21 was replaced by PPN 006 under the Procurement Act 2023);
Where 'proportionate' and ‘relevant’ (leaving some discretion to the contracting authority).

The NHS adopted the same requirement for its own contracts worth £5m or more from April 2023. In April 2024, the NHS extended the PPN 06/21 requirements to all new procurements, using two tiers. Contracts worth £5m or more a year, and all new NHS frameworks and dynamic markets regardless of contract value, need a full CRP. Smaller contracts above the procurement threshold need a Net Zero Commitment instead: a public commitment to reach Net Zero by 2050 or earlier, without measuring a carbon footprint or detailing how the target will be achieved.

This all sounds pretty confusing - so, what’s the key takeaway? so Developing and publishing a CRP is increasingly a requirement across NHS procurement, and from April 2027 it becomes the minimum for all in-scope contracts. Until then, a Net Zero commitment is the minimum for smaller NHS contracts, and making one without first understanding your footprint means you do not know what you’re committing to.

The new NHS Carbon Reduction Plan: rules from 1 April 2027

On 9 June 2026, NHS England published updated guidance that sets out new Carbon Reduction Plan (CRP) requirements that will apply to procurement from 1 April 2027.

The headline: from 1 April 2027, the Net Zero Commitment option goes and every in-scope procurement will need a CRP. For contracts worth £5m or more a year, and all new frameworks and dynamic markets, the new 2027 NHS CRP must cover global operations, not just the UK, and all relevant Scope 3. On top of the hard requirements, the NHS also recommends a 2045 Net Zero target with independent validation, and disclosure of how much of your target relies on offsetting.

Whether the new rules apply depends on contract value and procurement mechanism (i.e. standalone contract, framework, or dynamic market). To learn more about the new rules, read our detailed guide to the updated NHS Net Zero Supplier Roadmap.

How to improve your footprint

The carbon reduction plan isn’t just about reporting and sharing your emissions - it’s also designed to help organisations reduce their emissions and improve their carbon footprints. Plus, this is a worthy goal to work towards anyway.

So here are some steps you can take to improve your carbon footprint and stand a better chance of meeting the NHS requirements:

Start with an assessment of your carbon footprint. You should find the main sources of emissions in your operations and supply chain, then use this data as a baseline for setting realistic, measurable carbon reduction targets. Working with a carbon accounting platform like Seedling can help you achieve this.

Create a carbon reduction strategy that aligns with the NHS goals. Be specific about actions, timelines, and responsibilities, and prioritise activities that offer the greatest potential for carbon reduction.

Brainstorm ways to integrate sustainability into your operations. For example, you might switch to energy-efficient machinery, take steps to reduce waste, optimise transportation routes, and source sustainable materials. This should be a company-wide effort, so be sure to involve employees and stakeholders in your carbon reduction initiatives.

If possible, transition to renewable energy sources like solar, wind, or biomass. You can generate your own renewable energy on-site if possible, directly invest in renewable energy projects, or purchase green energy from suppliers.

Continuously monitor your progress towards your carbon reduction targets - this will help you identify areas for improvement and course-correct to reach your goals, as well as making it easier to report your progress transparently to the NHS and your other stakeholders.

Getting help and resources

Understanding and complying with the NHS Carbon Reduction Plan might seem like a bit of a daunting task at first, but with the right approach and support it becomes much easier and will benefit your organisation in a ton of different ways.

The good news here is that there’s a lot of help available for businesses who want to achieve their net zero goals and adhere to the NHS CRP guidelines.

For example, the UK Business Climate Hub is a great resource for UK SME businesses to help make climate change commitments.

One thing to keep in mind is that sustainability is an ongoing process. You should always be seeking out new opportunities to improve your carbon reduction efforts, and consciously keep up with the latest developments in sustainability, technology, and regulatory requirements.

By measuring your carbon footprint and working with partners like Seedling, you’ll not only align with the NHS requirements and remain competitive when it comes to procurement, but you’ll also build a more sustainable, future-proof organisation committed to saving the planet.
