Carbon accounting software with Sage integration
Connect Sage and the spend you already record becomes a spend-based Scope 3 baseline, calculated against published UK factors.

Scope 3 from the ledger you already keep
Your Sage ledger records what your business buys. That is where most companies' Scope 3 emissions sit.
Emissions calculated from your Sage spend
Gaia takes the transactions from your Sage ledger and converts them to emissions using published spend factors, so your Scope 3 baseline builds itself from data you already trust for your accounts. Because spend factors are tied to a price year, figures are inflation-adjusted to that year per currency using CPI data, following GHG Protocol Scope 3 guidance, with every adjustment reasoned and auditable.

Teach it your nominal codes once
Map each nominal code in your Sage chart of accounts once, to an activity, a category group, or excluded, and every future import categorises itself. Non-emitting codes such as wages, VAT and depreciation stay excluded so they never inflate the footprint, and a changed mapping only affects future imports: your reported history is never quietly rewritten.

UK Government factors, auditable end to end
Emissions are calculated against the UK Government's published conversion factors, and every figure in Gaia shows how it was calculated, so your SECR and GHG Protocol reports rest on numbers an auditor can follow.

Add the energy and fuel your ledger can't see
Sage tells Gaia what you spend; your bills say what you consumed. Upload an electricity, gas or fuel bill as a PDF or a photo and Gaia reads the consumption from it, with a person confirming every extracted figure before it counts and the bill kept attached as audit evidence. Spend plus consumption gives you Scope 1, 2 and 3 in one platform.

Sage integration FAQs
How does the Sage carbon accounting integration work?
You connect Sage to Gaia and your ledger transactions come across, are categorised through your chart of accounts mapping, and are converted to emissions using published UK conversion factors. The result is a spend-based Scope 3 baseline built from the records you already keep.
What if some of my spend shouldn't carry emissions?
Exactly why mapping lives at the nominal-code level: codes like wages, VAT and depreciation can be excluded once and stay excluded, so payroll never inflates your footprint.
Can I improve on spend-based figures later?
Yes. Spend-based is the GHG Protocol's recognised starting point, and every figure in Gaia carries a data-quality tier. As suppliers give you real activity data, those entries replace the spend-based ones and your quality mix improves, visibly.
Which plans include the Sage integration?
Accounting integrations are included on the Pro and Enterprise plans. See pricing for the full comparison.
