4 Reasons Your Carbon Reduction Plan Will Fail a Public Sector Bid
You are midway through a lucrative public sector or NHS tender. The bid looks strong. Then you reach the Selection Questionnaire stage and encounter a mandatory, pass/fail requirement: a compliant Carbon Reduction Plan (CRP).
If yours is missing or does not meet the government's formatting requirements, your bid is at risk of not progressing. All NHS tenders require a completed CRP and most procurement processes treat this as a pass/fail requirement.
For many SMEs, this is where careful preparation makes the difference. What follows are four areas worth getting right, and exactly what to do about each one.
First, a quick recap: what is a Carbon Reduction Plan?
A Carbon Reduction Plan is a formal, public document that sets out your company’s current carbon footprint and your commitment to achieving Net Zero by 2050 at the latest. Under the PPN 006 framework, it is required for any supplier bidding on central government or agency contracts valued at £5 million or more per annum, and for NHS contracts across an expanding range of procurement categories regardless of value.
Local councils, universities, and police forces are also increasingly adopting the same requirement in their own tendering processes - so the mandate extends well beyond central government in practice.
Crucially, a CRP is not a general sustainability statement. A PDF explaining that your office recycles and uses LED bulbs will not meet the requirement. The document requires a detailed, DEFRA-backed calculation of your UK operational footprint, aligned with the GHG Protocol and, where applicable, the ISO 14064 standard.
Mistake 1: Guessing the numbers
The most common error, and the easiest for auditors to spot, is estimated data. You cannot approximate your Scope 1 (direct fuel combustion) and Scope 2 (purchased electricity) emissions. Your raw utility and fuel data must be converted using the latest official DEFRA conversion factors, and your methodology must align with the GHG Protocol.
If the calculations do not stack up, the submission is unlikely to pass.
The fix: Use actual meter readings and fuel invoices. If you work with a specialist, they will process your raw data against current DEFRA factors - no guesswork involved.
Mistake 2: Assuming zero emissions because you don’t pay the bills
Many SMEs operate from leased offices, serviced workspaces, or co-working environments where energy costs are bundled into the rent. A common assumption is that because there is no direct utility bill, Scope 1 and 2 emissions are zero.
Under the GHG Protocol, you are still required to report your proportional share of the building's energy consumption. Zero reported emissions for an office-based business is likely to raise questions during a compliance review.
If you occupy a defined office space, whether you own it, lease it, or your energy costs are included in your rent, you are expected to report your energy emissions. Where direct meter data is unavailable, a proportional estimate based on your floor area, headcount, and official DEFRA benchmarks is an accepted approach, provided the methodology is documented. What matters is that the methodology is reasonable and justified.
The position is different if you operate from a fully serviced or managed office where facilities are shared with other organisations and you have no defined space or operational control over the building's energy use. In this situation, the energy emissions fall under Scope 3 Category 8 rather than Scope 1 or 2 under the GHG Protocol operational control approach. Reporting zero for Scope 1 and 2 is technically correct in this case, provided the boundary decision is clearly explained in your methodology.
The fix: Do not submit zero for Scope 1 or 2 without a clear methodology note explaining why. In most cases a proportional estimate is required, and a good specialist will handle this as part of the standard process.
Mistake 3: Missing the mandatory five Scope 3 categories
This is where the DIY plans can fall short. The government does not require you to report all 15 categories of Scope 3 emissions, but it does require five specific ones. Omitting even one makes your plan non-compliant:
• Business Travel (flights, trains, taxis, hotels)
• Employee Commuting (how your staff travel to work)
• Waste Generated in Operations
• Upstream Transportation and Distribution (deliveries to you)
• Downstream Transportation and Distribution (deliveries from you)
These five categories are not optional additions - they are mandatory fields in the PPN 006 framework. If your plan lacks reported data for any of them, it is unlikely to meet the standard.
If you do not have precise figures for all five - for example, exact commuting data for every member of staff - DEFRA proxy methods exist for each category. The key is that whatever approach you use is documented and defensible.
The fix: Treat these five categories as a non-negotiable checklist before submission. If you are unsure how to calculate any of them, a specialist will handle the methodology and ensure the figures are compliant.
Mistake 4: Getting the governance wrong
Even a technically accurate CRP will fail if the governance is not in place. A compliant plan must be:
• Formally signed off at board level or by a company director
• Published publicly on your company website
• Live at the time of bidding - the tender portal requests a URL, not just a file upload
A draft sitting in someone’s downloads folder, or a document signed by a department manager rather than a director, does not meet the standard. The governance requirement is non-negotiable.
The fix: Build the sign-off and publication steps into your bid timeline. Allow at least two to three working days for board review and website upload before the submission deadline.
Working to a tight deadline?
If you are mid-bid and have just hit the CRP requirement for the first time, 10 working days is our standard turnaround - but if your deadline is closer than that, get in touch on your discovery call so we can understand your timeline.
Your CRP is not a one-off document
DEFRA conversion factors are updated annually and your operational footprint changes as your business evolves. A CRP produced without an annual refresh will use outdated emissions factors and will not include your most recent emissions data, meaning it no longer accurately reflects your business and risks failing compliance checks on your next submission.
Building in an annual review process protects future bids and ensures your published document remains accurate and audit-ready.
