Short answer
Yes — procurement teams assess Carbon Reduction Plans against the content requirements of the PPN 006 technical standard, not against who produced the document. A compliant CRP must follow the official template, report Scope 1, 2 and the five required Scope 3 categories using GHG Protocol methodology and current DEFRA conversion factors, commit to Net Zero by 2050, be signed off by a director, and be published on your website. A software-generated plan that meets those criteria is as valid as a consultant-written one.
There is a persistent worry that a Carbon Reduction Plan produced by low-cost software will be spotted and thrown out. It will not. The rules that govern CRP acceptance — set out in the government's PPN 006 policy and its accompanying technical standard — are entirely about what the document contains, never about the tool or consultant that produced it. This guide walks through exactly what an assessor checks, why some cheap plans genuinely do fail, and how each of those failure modes is designed out of a plan built to the standard.
When a bid reaches the selection stage, the assessor works from a checklist derived from the technical standard published alongside the policy by the Government Commercial Agency (GCA, formerly Crown Commercial Service). According to the PPN 006 guidance on GOV.UK and the accompanying GCA technical standard, a compliant Carbon Reduction Plan must:
Every item on that list describes the document, not its origin. Nothing in the standard asks who drafted it. The same criteria apply to NHS procurements, where NHS England's Greener NHS programme aligns its supplier requirements with PPN 006. For a fuller walk-through of the policy itself, see our PPN 006 explained guide.
Low-cost plans that fail almost never fail because they were cheap — they fail because they are incomplete. Reading the GCA technical standard against the plans that get bounced, the same handful of gaps come up again and again:
None of these are problems of authorship or price — they are problems of content and process. A consultant-written plan with the same gaps would be rejected just as fast. The fix is to close every gap, whoever produces the document.
Because the failure modes are specific and repeatable, they can be designed out. CarbonPass maps a safeguard to each one, so the common reasons a cheap plan gets rejected simply cannot occur in the output:
| Failure mode | CarbonPass safeguard |
|---|---|
| Missing Scope 3 categories | All five mandatory categories captured and reported |
| Wrong template structure | Official template structure enforced automatically |
| No baseline year | A baseline year is required before the plan generates |
| No director sign-off | Built-in director sign-off block on the document |
| Not published | A publish step produces a live Carbon Passport URL |
The methodology behind the numbers uses GHG Protocol and current DEFRA factors, applied automatically from your bills, so the calculation itself is not a place where a cheap plan can quietly go wrong. If you are weighing the options, our CRP cost guide compares DIY, software and consultancy side by side, and our consultant vs software decision guide helps you pick honestly between the two paid routes.
Software closes the structural gaps; the optional £100 Completion Check adds a human read before you submit. A person reviews the finished plan and confirms four things:
It is important to be precise about what this is not. The Completion Check is a completeness review, not a certification, not an independent audit, and not a guarantee that your bid will be awarded — award decisions rest with the buyer against the whole tender, not just the CRP. What it does is give you a second pair of eyes so that the plan you publish and link in your submission is complete against the standard. For the template itself, see our Carbon Reduction Plan template guide.
No. Assessors check the content of your Carbon Reduction Plan against the PPN 006 technical standard, not who or what produced it. There is nothing in the standard that requires a plan to be written by a consultant, and no field on the assessment checklist asks about authorship. A software-generated plan that contains every required section is treated identically to one drafted by hand.
The common failure modes are all about missing content: fewer than the five mandatory Scope 3 categories, a structure that does not follow the official template, no stated baseline year, no director-level sign-off, and — surprisingly often — a plan that was never actually published on the supplier’s website. Any one of these can see a plan rejected at the selection stage regardless of how it was produced.
Yes, provided it meets the PPN 006 content criteria: the official template structure, Scope 1, 2 and the five required Scope 3 categories, GHG Protocol methodology with current DEFRA factors, a Net Zero by 2050 commitment, director sign-off and website publication. CarbonPass is built to satisfy every one of these, so its output stands on the same footing as a consultant’s document.
The £100 Completion Check is a human completeness review. A person confirms that every PPN 006 section is present, that the figures are internally consistent, that the methodology is declared, and that the plan is ready to publish. It is not a certification, an audit, or a guarantee that you will win a contract — it is a second pair of eyes before you submit.
