The spreadsheet problem.
Every year. For everyone.

Most UK manufacturers with 250–500 employees are filing SECR reports built on manually maintained spreadsheets. The data is hard to defend, the methodology is rarely traceable, and the Finance Director signing the document often cannot fully explain the numbers.

Wrong distances for flights

Spreadsheets typically use road distances or estimates for flights. DEFRA requires a specific methodology. If your statutory filing uses the wrong method, the number is wrong — and it is signed.

No formula trail

An auditor asks how you calculated the number. A spreadsheet gives them a total. CarbonTrack gives them the full working for every single entry — distance, factor, formula, result. One of those answers passes an audit. One does not.

Outdated emission factors

DEFRA updates its GHG conversion factors every year. Many companies are still using older factors in current filings. Using the wrong factor year in a statutory document is a factual error — regardless of intent.

PPN 06/21 disqualification

A Carbon Reduction Plan that cannot be verified by procurement is grounds for automatic disqualification. You lose the bid — not because your emissions are too high, but because the data behind them cannot be checked.

Built for one person.
Doing the job of three.

You are in finance, operations, or compliance at a UK manufacturer or contractor. SECR reporting is a legal requirement but it is not your only job. There is no sustainability team. There is a spreadsheet and a deadline.

The situation
  • 150–300 travel entries per year sitting in a spreadsheet
  • Someone spending 2 weeks per year manually applying DEFRA factors
  • A Finance Director signing a statutory document they cannot fully defend
  • A PPN 06/21 submission where the methodology is not traceable
What changes
  • Every trip logged at source — 45 seconds per entry
  • DEFRA 2025 factors applied automatically — no manual lookups
  • Formula visible for every calculation — auditor-ready on demand
  • PPN 06/21 Carbon Reduction Plan generated in one click

The SECR stress cycle. CarbonTrack works with it.

Q1
The Scramble

Year-end. You're pulling 12 months of receipts, fuel cards, and flight emails. The spreadsheet is a mess.

"Upload your existing CSV. Get a clean DEFRA report in 24 hours."
Q2 · Now
The Tender Window

Bidding season. Government contracts require a verified Carbon Reduction Plan. You need it now.

"Don't let a calculation error disqualify a £5m bid."
Q3
The Quiet Period

Mid-year. The right time to get the system in place before the next reporting cycle begins.

"Set up log-at-source now. The data will be clean when January hits."
Q4
The Setup

Planning season. Lock in the system for next year so you're not scrambling again in Q1.

"Make next year's audit invisible."

Less than one
auditor hour.

External auditors charge £150–£300/hour to verify carbon data. At £450/month, CarbonTrack makes every calculation self-verifiable — the auditor checks the work, they do not reconstruct it.

A full SECR audit typically takes 4–8 hours of auditor time. That is £1,200–£2,400 per year. Against that, £450/month is not a software cost. It is risk mitigation.
