Carbon accounting software that keeps your numbers straight.
Carbon accounting is bookkeeping for emissions — and like bookkeeping, it only works if the method is consistent and the trail is auditable. Compare Your Footprint gives UK SMEs a repeatable way to account for Scope 1, 2 and 3 emissions against recognised factors, so this year's number stands up next to last year's.

What is carbon accounting software?
Carbon accounting software records and calculates an organisation's greenhouse gas emissions using standardised methods and emission factors, so results are consistent and auditable over time. Compare Your Footprint applies GHG Protocol and UK Government factors across Scope 1, 2 and 3 for UK SMEs, with a documented trail behind every figure.
Accounting you can rely on
One consistent method
The same boundaries and factors each period, so year-on-year comparisons are real, not artefacts of how you counted.
Factors you can cite
GHG Protocol and UK Government conversion factors, documented against every line so any figure can be traced back.
AI-assisted data matching
Spend, invoices and utility data mapped to the right factors automatically — no manual lookup.
Full Scope 3 ledger
All 15 categories, so purchased goods, travel and supply chain aren't left as a gap.
Audit-ready exports
A methodology trail structured for UK SRS assurance requirements coming into effect from 2027.
Benchmarked context
Every account compared against similar UK organisations, so the numbers have meaning.

Why “accounting” matters, not just “a number”
A one-off estimate answers a question once. Accounting answers it every year, the same way, so a buyer or auditor can trust the trend. Consistent boundaries and documented factors are exactly what assurance needs — and what turns a footprint from a marketing number into evidence.
Where it fits
If you just need to measure and share a footprint, see carbon footprint software. For the disclosure output itself, carbon reporting software. And when you're managing reduction across a team, carbon management software.
Carbon accounting software FAQs
What is carbon accounting software?
Carbon accounting software records and calculates an organisation's greenhouse gas emissions using standardised methods and emission factors, so results are consistent and auditable over time. Compare Your Footprint applies GHG Protocol and UK Government factors across Scope 1, 2 and 3 for UK SMEs, with a documented trail behind every figure.
How is carbon accounting different from a carbon footprint?
A carbon footprint is the result: your total emissions for a period. Carbon accounting is the disciplined, repeatable method behind it — consistent boundaries, documented factors and an audit trail — so each year's footprint is comparable and defensible.
What emission factors does Compare Your Footprint use?
Compare Your Footprint uses GHG Protocol and UK Government (DESNZ/Defra) conversion factors, documented against every line so any figure can be traced back to its source.
Can it handle Scope 3 emissions?
Yes. All 15 Scope 3 categories are supported alongside Scope 1 and 2, including purchased goods and services, business travel and the wider supply chain.
How much does carbon accounting software cost?
Compare Your Footprint starts from £299 per year, with a free trial and no credit card required. Output is formatted for SECR-style disclosure and structured for UK SRS assurance ahead.
