Best carbon accounting software is priced before the sales call

Every incumbent in this category is quote-based. We publish our pricing and let you run the product on your own data first. Yearly billing is the default, at 50% off monthly, and the switch below moves the whole table to monthly. If you are building a budget rather than picking a plan, we break down what carbon accounting software costs across the category, including the line items that sit outside the license.

Get started

Yearly billing shown by default. Every plan is a subscription: monthly or yearly, cancel from your own billing portal, payments final under the refund policy. Prices are per workspace and exclude local sales tax where it applies.

There is no free tier. The live demo is the free taste: the real classification pass, ungated, on your own data. The alternative this pricing competes with is not a $49 tool; it is a consulting engagement, repeated every year.

02 Security

Security & control · what the product does today

Seats with roles

The workspace owner invites each person by email as an editor or, on Assurance, as a read-only viewer. Every seat has its own private link, and revoking a seat kills that one link.

Audit log with who and why

On Compliance and above, imports, overrides, factor choices, seat changes and exports are recorded as append-only events with the person who made them, and an override needs a written reason. Nothing in the log can be edited or deleted.

Methodology history + restatements

On Assurance, every method or factor change is a dated version with its reason, and a correction to a closed period is a restatement with its reason, so last year's number can be reproduced after the method changed.

Read-only access for your assurance provider

On Assurance, your auditor gets a viewer seat: postings, evidence and the log are open to read, and nothing can be changed from that seat.

Encrypted in transit, yours to take out

Every page and file moves over HTTPS. The ledger exports to CSV and XLSX whenever you want it, and the card, invoices and cancellation live in your own billing portal.

This list describes what the product does, not a certification. We hold no SOC 2 attestation and no ISO 27001 certificate today, and we will not imply otherwise. We publish no uptime percentage and sign no availability SLA. We do not print badges we have not earned.

03 Pricing questions

Asked by the budget owner

Pricing questions, answered plainly

01 Why these numbers?

Because the comparison is a consulting engagement, not another SaaS line item. A first inventory bought as hours costs multiples of the Ledger tier and produces a document instead of a system. We do not put competitor prices on this page. Most vendors do not publish enterprise pricing, and where one does, the comparison pages quote it from the vendor's own site, so we will not fabricate a comparison column. Their pages ask you to call; ours says the price of every plan we sell.

02 What does the ROI case look like without invented numbers?

Time: the classification pass over an AP export is the multi-week part of a first inventory, and that is the automated part; your reviewer reviews instead of typing. Money: a subscription is a retained asset, next year starts from this year's ledger instead of a blank engagement. Risk: an assured disclosure needs lineage a spreadsheet cannot reproduce eighteen months later. We do not print an hours-saved figure, because we have not measured yours.

03 Is there a plan for consultants?

Yes. One account holds a workspace per client, each with its own entity, ledger, evidence and plan, so every client pays for the depth it needs: Ledger for a first inventory, Compliance for a CSRD or SB 253 client, Assurance for a group going through assurance. The classification runs per client and you keep the advisory margin. You open each client workspace yourself from your account.

04 What happens when I create an account?

You confirm your email with a 6-digit code and land in your account, where the plans are. Your workspace opens as soon as you pick one; the classification demo runs before that, on your own data, so you buy with the output in front of you.

05 Can prices change?

A price change never applies to a running subscription mid-term. You see any change before your next renewal, and nothing is charged without you subscribing first.

Run it on your own numbers first.
