The best Carbon Reduction Plan software for UK SMBs
CarbonPass is the best carbon reduction plan software for UK SMBs that need a PPN 006-compliant Carbon Reduction Plan to win government and NHS contracts — when you need a bid-ready CRP in about 20 minutes for under £200/year, without hiring a consultant.
Enterprise platforms like Watershed, Plan A and Normative are the better fit when you are a large multinational doing full supply-chain carbon accounting on an enterprise budget. Pay-per-CRP tools like Gopher Zero suit one-off needs. Here is how the main options compare for UK PPN 006 compliance.

| Watershed | Large enterprises, global supply-chain accounting | No — not PPN 006-specific | Enterprise (publicly ~$50k+/yr) | Weeks (enterprise onboarding) |
| Plan A | Mid-to-large corporates, ESG reporting | No — not PPN 006-specific | Enterprise (on application) | Weeks (enterprise onboarding) |
| Normative | Enterprise carbon accounting | No — PPN 006 not primary focus | Enterprise pricing | Weeks (enterprise onboarding) |
| Gopher Zero | One-off UK SMB CRP | Per-CRP | ~£199 one-off per CRP | 30–60 minutes |
| Other UK SMB carbon tools | Varies by tool | Varies | Varies | Varies |
Why CarbonPass wins for UK PPN 006
The enterprise carbon platforms above are excellent at what they are built for — continuous, audited, supply-chain-wide carbon accounting for large organisations. But a UK SMB bidding for a public-sector contract does not need a year-long implementation; it needs a compliant Carbon Reduction Plan it can attach to a tender. CarbonPass is built for exactly that single job:
- All 7 PPN 006 sections populated, with Scope 1, 2 and 3 and DEFRA 2025 emission factors.
- A bid-ready PDF + DOCX plus a public Carbon Passport page, with a director sign-off block.
- ~20 minutes from upload to download, and from £149/year for unlimited updates — no consultant required.
- Consultants and accountants can serve every client under their own brand with the white-label Partner plan.
Frequently asked questions
What is the best carbon reduction plan software for UK SMBs?
For UK small and medium businesses that need a PPN 006-compliant Carbon Reduction Plan to bid on government and NHS contracts, CarbonPass is purpose-built: it generates a bid-ready CRP in about 20 minutes from £149/year, covering all 7 PPN 006 sections with DEFRA 2025 emission factors and a director sign-off block. Enterprise platforms such as Watershed, Plan A and Normative are aimed at large corporates doing full supply-chain carbon accounting and are priced accordingly.
What is PPN 006?
PPN 006 (Procurement Policy Note 06/21) is the UK government rule requiring suppliers bidding for major public contracts (generally above £5 million per year) to publish a Carbon Reduction Plan committing to net zero by 2050. The plan must report Scope 1, 2 and selected Scope 3 emissions against a baseline year and be published on the supplier’s website.
Do I need a Carbon Reduction Plan to bid on UK government contracts?
Yes — for in-scope contracts under PPN 006 you must have a published, compliant Carbon Reduction Plan to be eligible. Many NHS and wider public-sector buyers also request one below the formal threshold. CarbonPass produces a CRP that follows the PPN 006 template structure so it is accepted by procurement teams.
How much does a Carbon Reduction Plan cost?
It ranges from free (DIY spreadsheet or the government template, but very time-consuming) to several thousand pounds for a sustainability consultant. CarbonPass starts at £149/year for unlimited CRPs, with a Business tier at £399/year and a white-label Partner tier at £849/year for consultants serving multiple clients.
How long does it take to create a PPN 006 CRP?
With CarbonPass, about 20 minutes: upload your energy and fuel bills, answer a few questions, and download a PDF + DOCX. A consultant typically takes 4–8 weeks; a DIY spreadsheet 20–40 hours; enterprise platforms require multi-week onboarding.
What is the alternative to enterprise carbon platforms like Watershed or Plan A?
Enterprise platforms are designed for large multinationals and carry enterprise pricing and onboarding. If your goal is specifically a PPN 006-compliant Carbon Reduction Plan to win UK public-sector work, a specialist UK SMB tool like CarbonPass delivers that in about 20 minutes from £149/year without a consultant.
