Sage carbon accounting and Sage Earth carbon accounting compared for US Sage Intacct, Sage 100 and Sage 50 users

This page is for a US controller, finance director or operations lead whose books run on Sage and who now has a carbon request with a date on it: a large customer's supplier questionnaire, a CDP response, a bank asking for emissions data, or a parent company in scope for California SB 253. You searched for Sage carbon accounting because the obvious first move is to ask whether your accounting vendor already does it. Here is what Sage sells today, where it fits, and what a US Sage shop can use instead.

Everything about Sage on this page comes from Sage's own material: the September 30, 2025 launch announcement, the Sage Earth product and enterprise pages, the Sage Earth Carbon Accounting methodology article (dated August 27, 2026), the Sage Intacct help page for the Sage Earth add-on, and Sage's February 2024 announcement with AWS. All were read in October 2026.

Yes. Sage sells Sage Earth Carbon Accounting, which came from Sage's 2022 purchase of the UK start-up Spherics. Since September 30, 2025 it is included "at no extra cost" for all Sage Accounting and Sage for Accountants customers in the UK. It reads spend from the accounting ledger, uses AI to categorize transactions, applies emission intensity factors and organizes the result into GHG Protocol scopes. Sage also sells a Carbon Accounting API to banks and fintechs and an enterprise version that collects data from small suppliers.

The product is aimed squarely at small businesses. Sage's own enterprise FAQ says Sage Earth "is not designed to calculate a full enterprise-level corporate footprint." Its job is to give a small supplier a credible carbon profile to hand to a bigger customer.

Not as a US product that we could find. The 2025 launch was announced for UK customers. The Sage Intacct help page for the Sage Earth add-on lists the United Kingdom as its only region. Sage's US website has no Sage Earth page (the US address returns a "not found" page in October 2026), and the methodology lists UK and European data sources. In February 2024 Sage said Sage Earth would reach AWS Marketplace in the UK and Ireland, "with plans to extend to North America and across Europe over the next 18 months." That window closed in August 2025, and we found no North American launch announcement since.

Plans change, so ask your Sage account manager or partner directly. For budgeting a 2026 filing or customer deadline, assume the Sage-native option is not available to a US entity.

Sage publishes its methodology, which is more than many vendors do, and it is candid about the limits. Read against a US reporting request, four of them matter.

None of this makes Sage Earth a poor product. For a UK micro business answering a tender question, a free footprint inside the books it already uses is a good deal. The limits only bite when the number has to survive someone else's review, in a US reporting context, on US factors.

For UK Sage Accounting customers, Sage Earth Carbon Accounting is included at no extra cost. For enterprises that roll it out to their small suppliers, Sage describes the price as "hundreds per supplier, not thousands" without a list price. Sage publishes no US price because it publishes no US product. If your auditor or customer wants a US inventory, the real comparison is not Sage Earth against a paid tool. It is a paid tool against a consultant, which is where most US mid-market companies end up when their software vendor has nothing to offer.

The top bar is the California Air Resources Board's own estimate of what SB 253 Scope 1 and 2 reporting costs one company a year, from its regulatory impact assessment; the breakdown is on SB 253 compliance cost. Our own prices are on the pricing page: Ledger at $390 a month or $2,340 a year, Compliance at $1,290 a month or $7,740 a year, and Assurance at $3,900 a month or $23,400 a year. Published prices for the larger platforms, from Persefoni to Watershed, are collected on carbon accounting software cost.

In the UK, Sage Intacct customers can add a Sage Earth component that shows an industry-average footprint. Setup asks for two custom fields on each entity, the industry sector and last year's revenue, and the dashboard then estimates Scopes 1, 2 and 3 from those two numbers. That is a useful first look, but it is an estimate about companies like yours, not a calculation from your own transactions. In the US, Sage Intacct has no Sage-native carbon module that we could find, so US customers either add a third-party tool or start from an export.

The export route is simpler than it sounds. Sage Intacct, Sage 100 and Sage 50 all export vendor bill detail and general ledger detail to CSV or Excel. That file carries everything an inventory needs to start: the vendor, the GL account, the description, the date and the amount.

CarbonAccounting.ai starts from the accounts payable or GL export your Sage system already produces. It proposes a GHG Protocol scope and one of the 15 Scope 3 categories for every line, gives a reason and a confidence score, and sends only the uncertain lines to a reviewer. US entities are calculated on EPA USEEIO spend factors and eGRID grid electricity factors, and the factor used is stored with each line so a reviewer can check it. Utility invoices and fuel cards land in Scope 2 and Scope 1, and the Compliance plan adds activity-based factors so kilowatt-hours and gallons replace dollars where you have them.

The point of the design is the review. When a customer, a CDP scorer or an SB 253 assurance provider picks one figure and asks where it came from, you open the line: the Sage vendor, the invoice description, the category, the factor and who approved it. That is the evidence an industry-average estimate cannot give you.

Sage 100 and the US edition of Sage 50 have no built-in carbon module either. The workflow is the same as for Intacct: run the vendor purchase history or GL detail report for the reporting year, export to Excel, and upload. Distribution and light manufacturing companies, which are much of the Sage 100 base, usually find that a handful of suppliers (freight, packaging, raw materials, energy) make up most of their footprint, so the review queue is shorter than the line count suggests. The carbon accounting for manufacturing and logistics pages show what those categories look like.

If your books are on another system, the NetSuite carbon accounting guide and the Microsoft Dynamics 365 guide cover the same choice. Small US companies comparing tools in this price range should read the Aclymate alternatives page and simple carbon accounting software.
