Xero carbon accounting software for a Scope 1, 2 and 3 footprint from your bills and spend

This page is for the owner, finance manager or outsourced bookkeeper of a US company that runs on Xero and has just been asked for a carbon number. The request usually arrives from a larger customer with a supplier questionnaire, from a lender, from a CDP or EcoVadis request, or from an investor or parent company that has to report. Nobody on your team is a sustainability specialist, and you do not need one to start. You have a general ledger, and a ledger is the right raw material.

Not as a native feature in the accounting product. Xero stores a $3,800 electricity bill as a payable to a utility vendor in an expense account, and nothing in the file turns it into kilowatt-hours or tonnes of CO2e. Carbon tools fill that gap from outside, either through an app that connects to the organisation or through an export. The export route has one practical advantage: it does not depend on a connector, so it works the same for a Xero organisation, a demo company you are testing on, and a ledger that was migrated from another system last year.

In Xero, open the Account Transactions report, or the Payables transactions by supplier, set the date range to your reporting year, include every expense and cost of sales account, and export to Excel. Keep date, supplier, account code, description, amount and, if you use them, the tracking categories for site or department. Save as CSV or XLSX. That one file is the whole input.

Classification then does three jobs. It separates Scope 1 (fuel you burn, company vehicles, refrigerants), Scope 2 (purchased electricity and heat, from the utility bills) and Scope 3 (everything else you buy, which for most small and mid-size companies is the bulk of the footprint). It assigns each line one of the 15 Scope 3 categories, for example purchased goods and services, business travel or waste. And it applies a US factor, with the source and year stored on the line. Lines the model is unsure about are flagged for you instead of guessed. The method behind spend-based figures is explained in how to calculate Scope 3 emissions, and the EPA publishes the factors in its GHG Emission Factors Hub.

The Ledger plan is $2,340 a year and covers Scope 1, 2 and spend-based Scope 3 screening for one company from the export, with the column mapping kept so the next run is quick. The Compliance plan is $7,740 a year and adds activity-based factors, supplier data requests and report packs for SB 253, CSRD, CBAM and ISSB. Both are on the pricing page. A consultant doing the same inventory is priced per engagement and normally delivers it once, without a workspace you can re-run; that trade is worked through in carbon accounting services vs software.

Three things in a Xero export deserve attention before you trust any footprint. First, account codes are often too coarse: a single "Office and general" account can hold stationery, a courier and a flight, and only the line description tells them apart, which is why classification works on the description and supplier, not just the code. Second, if you invoice in several currencies, convert to USD at the transaction date before applying US spend factors. Third, expenses paid by staff and reclaimed through an expenses tool arrive as one reimbursement line, so export the claim detail if travel matters to your inventory. None of this is exotic. It is the same cleanup a year-end audit would ask for.
