How does CO2 Lab access my Xero data?

Via a secure OAuth 2.0 connection, and read-only. We read transactions to build your spend document. We never modify your Xero records.

Does spend go straight into my footprint?

No. On import you first see a per-account preview of exactly what's coming in. Then our analyst categorises it and you review every figure before it lands in your inventory.

How accurate are spend-based calculations?

Spend-based methods use industry-average emission factors and are a recognised approach under GHG Protocol. For higher accuracy, supplement with activity-based data from invoices or bills.

What if I import the same year twice?

The previous Xero import for that year is superseded automatically, so nothing is double-counted.

Your Xero spend, in your carbon ledger

Connect Xero and pull a full financial year of supplier spend in one click. You see exactly what's coming in, rolled up per account, drillable to the line, before a single row touches your footprint. Our analyst then cleans, categorises and estimates the emissions, and you stay the reviewer. Read-only: we never change your Xero records.

How it works

Connect Xero

Authorise CO2 Lab to read your transactions via secure OAuth. Read-only: we never modify your Xero data.

Preview the year's spend

Pick a reporting year and see the supplier spend we'd bring in, rolled up per account and drillable to each line. Nothing is written until you import.

Analyst categorises, you review

On import, our analyst cleans, excludes and categorises the spend into GHG Protocol categories with spend-based factors, then you review every number before it lands in your footprint.

How teams use it

Spend-based Scope 3

Turn a year of purchase transactions into Scope 3 estimates: no spreadsheets, no manual entry.

Preview before commit

See exactly which accounts and line items are coming in, biggest spend first, before anything is written.

Financial-year alignment

Imports align to your financial year, so emissions match your reporting periods.

Safe re-imports

Re-import a year and the previous Xero data is superseded automatically, never double-counted.
