How Procurement Teams Evaluate Carbon Reduction Plans.
Understanding the CRP check helps you put the right effort into your plan, your tender response and the work needed to deliver your commitments.
- 12 min read
Key takeaways
Procurement teams use Carbon Reduction Plans to assess organisational capability as well as environmental performance.
Clear evidence, realistic commitments and good governance often carry more weight than ambitious carbon reduction targets.
Buyers are experienced at identifying documents prepared solely to satisfy a tender requirement.
A well-structured Carbon Reduction Plan strengthens trust by showing that sustainability is part of normal business management rather than a standalone compliance exercise.
Introduction
When a tender asks for a Carbon Reduction Plan, it can be difficult to judge how much detail to provide. You may already have emissions figures and a net-zero commitment but still wonder whether the buyer expects a more ambitious target, a longer list of projects or a detailed investment plan.
The answer depends on what is being assessed. Under PPN 006, the buyer checks whether your CRP meets a defined standard. A separate environmental or social-value question may ask how you’ll deliver benefits through the contract. Those questions need different evidence, even when they draw on the same carbon data.
Understanding that distinction helps you prepare a useful submission, without spending time on additions that will not affect the CRP assessment. It also makes it easier to see where your business needs a fuller delivery plan behind its public commitments.
What the buyer is assessing
PPN 006 applies to specified central government bodies and relevant contracts above £5 million a year (inc VAT) subject to the policy’s scope and proportionality provisions. It is not a universal rule for every UK tender, your tender documents should identify the requirements and assessment approach that apply.
Within this setting, the CRP is a condition of participation: a requirement the supplier must satisfy to be awarded the contract. This part of the assessment is pass/fail. The buyer checks whether a plan meets the standard, rather than awarding more points to the most ambitious submission.
The Cabinet Office’s PPN 006 FAQs illustrate this with two compliant suppliers, one committed to net zero by 2050 and the other by 2030. Both pass. The earlier date does not give the second supplier an advantage in this check. That does not make ambition unimportant to the business but it does clarify what this particular assessment is designed to do.
A tender may also contain separate questions about environmental performance or social value. These should be answered against their own published criteria. Keeping the following purposes distinct helps the bid team decide what belongs where.
| What is being considered | Evidence used | How to respond |
|---|---|---|
| CRP requirement under PPN 006 | The published plan and required declarations | Demonstrate that the plan meets the specified standard. |
| Separate tender question, where included | The contract-specific response requested by the buyer | Explain the proposed delivery against the published criteria. |
| Delivery commitments | The actions and reporting agreed for the contract | Assign responsibilities and monitor the commitments made. |
These are different purposes, not a universal sequence or scoring model.
How the required standard is checked
The starting point is the organisation boundary. A well-presented plan can still leave a problem if its commitments and figures relate to a parent company. For example, a subsidiary might have access to its parent’s carbon report but no clear statement showing that the commitment applies to the business bidding for the work.
A parent-company CRP can be used only where the conditions in PPN 006 are met. The bidder must be wholly owned by the parent, expressly adopt the commitment, confirm that the measures can be applied when delivering the contract and publish the plan on its own website. Bidding entities must also take steps to obtain their own CRP as soon as reasonably practical. A group report is therefore not an automatic substitute for a plan covering the business submitting the bid.
The plan must confirm a commitment to achieving net zero by 2050 at the latest for the organisation’s UK operations. Its emissions reporting must cover Scope 1 and Scope 2 and five specified Scope 3 categories: upstream transportation and distribution, waste generated in operations, business travel, employee commuting, and downstream transportation and distribution. The technical standard ddescribes the reporting boundaries. The person preparing the figures needs to clarify the boundary, so the bid team can establish whether the required information is present.
The publication date and the period covered by the figures also need separate attention. The assessment guidance requires the CRP to have been published prior to the tender notice or within the preceding 12 months. Its assessment table also says the reporting period must fall no more than 18 months before the tender notice is published, subject to its provisions for an acceptable explanation.
The technical standard calls for the CRP to be reviewed and updated annually, within six months of the organisation’s financial year-end. Agreeing who will maintain the data and arrange the next review helps avoid discovering an overdue update when a tender arrives.
Approval and publication are separate tasks. The plan should state that the board or equivalent management body has approved it and give the approval date. A director or equivalent must sign it off, with their name, job title and date recorded. A physical signature is unnecessary, but the sign-off must be clear; the technical standard gives separate provisions for LLPs.
The latest plan should also be accessible through a prominent link on the organisation’s UK homepage. Where there is no website, the standard provides for supplying a written copy within 30 days of a request. Before submitting the bid, it’s worth checking that the link connects to the approved version.
The plan must also describe environmental management measures that will be applied when undertaking the contract. Explain the connection between these measures and the work your business does, rather than relying on a general sustainability statement.
The guidance allows acceptable explanations for specified reporting gaps and makes provision for new entrants trading for less than 12 months. These provisions need to be considered against the bidding entity’s circumstance, as they don’t guarantee acceptance of an incomplete plan. If in doubt, raise any unresolved questions through the procurement’s clarification process while there is time to address them.
What the emissions figures do and do not tell the buyer
A larger reported footprint does not, by itself, mean a supplier fails the PPN 006 check. The assessment guidance says the baseline and current emissions figures requested in its declaration are for information, rather than a basis for assessment. They may be used to track progress over time.
This matters when a business is growing or improving its data. A manufacturer might add a production line, increasing its reported emissions even while reducing the energy used for each unit produced. The total and the efficiency improvement tell different parts of the story. Both aspects of the bidding entity’s emissions are important to include to give a compete picture of the approach being taken.
Explain what has changed in the figures and what caused that change. If additional activities have been included, distinguish wider reporting from changes in operations. If an efficiency project is expected to reduce emissions, separate that forecast from reductions already measured. This helps readers understand progress without turning the figures into an additional procurement test.
The business still needs dependable calculations behind the published summary. Clear records of boundaries, data sources and assumptions help the team answer questions and prepare the next update. They also support better decisions about which emissions the business can realistically reduce.
Where a scored environmental response comes in
A compliant CRP does not automatically answer a separate question about what your business will deliver through a contract. The CRP describes the organisation’s emissions and measures. A contract response needs to explain the offer in the terms the buyer has requested.
Where a tender uses the PPN 002 Social Value Model, its guidance assesses the proposed method and implementation plan against published criteria. General corporate policies cannot stand in for contract-specific deliverables. Any social-value weighting belongs to that separate assessment, not to the CRP check.
As at October 2026, suppliers also need to allow for the transition to PPN 026. It sets out a revised Social Value Model focused on jobs and skills for relevant central government procurements commencing from 1 January 2027. Earlier transition is encouraged, although the previous model may be retained where changing would require disproportionate resources or invalidate earlier market engagement. The new model focusses on job creation and is quite different to the previous version where environental targets were able to be included, so it’s important to read the model and criteria named in the tender.
For example, a logistics company bidding for a delivery contract might be asked separately how it will reduce transport emissions during the contract. Its CRP may describe fleet renewal across the business, but the response needs to identify the vehicles or operating changes relevant to that work, when they could be introduced, and how delivery would be evidenced. The question and its criteria determine the detail needed.
The same care applies to the status of a project. A measure already in operation should be described as such. A proposal dependent on investment approval, needs that dependency explained. Copying an aspiration from the CRP into a firm contract commitment without involving operations and finance can leave the business promising something it has not planned to deliver.
Read the response requirements alongside the CRP so the documents remain consistent. Where commitments become part of the contract, delivery teams need to understand them before the bid is finalised.
How a Net Zero Roadmap supports delivery
The CRP is a summary document. A Net Zero Roadmap can provide the more detailed planning that helps the business decide how to act on its targets. Its value lies in connecting carbon reduction with operational decisions, responsibilities and investment over time.
Consider a logistics supplier planning to replace diesel vehicles. A target date alone does not resolve when leases end, whether suitable vehicles are available for the routes, where charging could be installed or how the expenditure will be funded. Working through those questions allows the business to distinguish actions it can commit to now, against options that need further investigation.
That distinction should carry through into the CRP and any relevant tender response. Measures already in place, approved projects and longer-term possibilities need to be described accurately. A roadmap gives the people preparing those documents a shared basis for discussing what the organisation can deliver.
For a medium-sized business, the plan can be proportionate to the decisions involved. Start with the material emissions sources and the actions most relevant to them, then identify the owner, timing, dependencies and basis for any expected reduction. Finance can consider expenditure alongside replacement cycles, while operations can assess service requirements and disruption. The person maintaining the CRP then has a clearer basis for how to report progress.
A separate roadmap is not required by PPN 006 and will not earn additional credit in its CRP check. Its value is in helping the business turn a target into decisions that people can carry out and review.
A final review before submission
Before submitting, bring the published plan and the tender requirements together. A short review with the person responsible for the data, the bid lead and the relevant delivery owner can help resolve inconsistencies while changes are still possible.
- Identify the applicable procurement requirements and the criteria for any separate environmental or social-value question.
- Confirm that the plan covers the bidding entity, its required net-zero commitment, the relevant emissions sources and reporting period.
- Check publication timing, approval, sign-off and the link supplied to the buyer.
- Explain any permitted reporting gaps and raise unresolved questions through the available clarification route.
- Make sure measures described in the plan and commitments in the tender response are consistent with what delivery teams understand.
- Assign responsibility for maintaining the CRP and monitoring any commitments made.
This review helps organise the submission. It does not replace the buyer’s assessment or resolve requirements that differ in the particular tender.
Questions suppliers ask
Can we use our parent company’s Carbon Reduction Plan?
Potentially, if all the PPN 006 conditions described above are met. The parent’s plan must expressly cover the bidder’s adopted commitment and applicable measures, as well as satisfying the ownership and publication conditions. Simply naming the subsidiary is not enough.
Is a Carbon Reduction Plan the same as a Net Zero Roadmap?
They serve related purposes: the CRP is the published summary, while a roadmap develops the actions, timing and responsibilities behind the target. The delivery planning described above can support the CRP but does not replace its required information.
Does PPN 006 require an independently audited carbon footprint?
No. The technical standard states that the footprint does not have to be audited. Independent assurance may be useful in other circumstances, but it should not be presented as a general PPN 006 requirement. Check separately for any additional requirements in the tender.
Do NHS tenders use the same requirements?
NHS England has its own CRP and Net Zero Commitment guidance. As at October 2026, it has also published new guidance taking effect from 1 April 2027. In-scope procurements started before that date continue under the previous requirements. Follow the guidance and tender requirements applying to your procurement.
Preparing a plan your business can maintain
Start by identifying what the tender requires from your plan and where the evidence is incomplete. Once those gaps are clear, the bid team can give any separate contract response the attention it needs, with delivery commitments agreed by the people responsible for carrying them out.
Where the target is clear but the next operational decisions are not, a delivery plan can help. Working through responsibilities, investment and timing gives the business something useful to act on and a stronger basis for its next CRP update.
