Gaia: cost, fit and limits
Gaia is a carbon accounting platform made by Gaia Technologies Ltd, a company registered in England and Wales, that measures Scope 1, 2 and 3 emissions and produces GHG Protocol, SECR and CSRD reports, billed monthly per organization.
What to know first
Gaia prices carbon accounting per organization instead of per user, in three tiers from £300 to £1,500 a month plus VAT. The cheapest tier covers full Scope 1 to 3 measurement but allows one login. Accounting integrations, CSRD and UK SRS reporting and supplier surveys start at Pro, while the API and SSO wait for Enterprise. The pricing pages describe the software as AI-powered but name no separate AI feature.

Who Gaia is best for
UK companies with SECR duties
SECR and GHG Protocol reports come with the £300 Start-Up plan, so a firm with a statutory reporting duty can start without moving up a tier.
Finance teams on Xero, QuickBooks or Sage
Pro lists integrations with all three accounting packages, which lets spend data feed the footprint instead of being keyed in by hand.
Firms answering CSRD or supply chain requests
Pro adds CSRD/ESRS E1 reporting, UK SRS reporting and supplier surveys with data collection tasks, covering the request side of Scope 3.

What Gaia does
- Scope 1, 2 and 3 measurement
- Measurement across all three scopes is part of the Start-Up plan, together with an audit trail, reduction targets and a register of carbon offsets, so the base tier is not limited to Scope 1 and 2.
- Standards-based reporting
- GHG Protocol and SECR reports come with Start-Up. Pro adds PPN 006, UK SRS and CSRD/ESRS E1 reporting, which is where a firm with disclosure duties will usually land.
- Accounting integrations
- Pro lists Xero, QuickBooks and Sage connections. Start-Up leaves them out, so entry-tier users work from uploaded bills and fuel documents, which the plan table shows as extraction without calling it AI.
- Supplier surveys
- Pro includes supplier surveys and engagement tracking with data collection tasks, a way to gather Scope 3 inputs from suppliers directly rather than estimating them from spend.
- Scenario modelling
- Pro adds scenario modelling and forecasting on top of the reduction targets that every plan includes, so a team can test a reduction path before committing to it.
- API and SSO
- API access and SSO with enforced MFA are listed on Enterprise only, along with white-labelling and client and partner portals for firms that run carbon accounting for others.
How Gaia handles your data
Gaia's privacy policy says the carbon accounting platform is hosted on Amazon Web Services in the UK, and the page shows a Cyber Essentials Plus badge. No SOC 2 or ISO 27001 is stated. The policy says personal data is kept only as long as needed or legally required, and also that other information may be kept indefinitely. It does not say whether customer data is used to train models. The hosting of the BNG Marketplace is not stated. The privacy policy names Gaia Technologies Ltd with company number 15056038 and a London address; it does not label that address a registered office or headquarters.
Where Gaia falls short in practice
- One login on the cheapest plan. Start-Up allows a single login, so a sustainability lead and a finance colleague cannot work in it at once. Multiple logins begin at Pro, which costs £650 a month plus VAT.
- Enterprise gates the API. Pro excludes SSO, white-labelling, client and partner portals, API access and custom integrations. A team that needs to pull emissions data into its own systems must go to the £1,500 tier.
- No AI feature named. The pricing page calls the product AI-powered in its menu text but lists no distinct AI function. Buyers who want a named assistant or model-driven classification cannot confirm one from these pages.

Gaia: common questions
How much does Gaia cost per month?
Gaia lists Start-Up at £300 plus VAT per month, Pro at £650 and Enterprise at £1,500, all billed monthly per organization. The page describes these as starting points, so the final amount may differ. A trial is offered at sign-up, but its length is not stated.
Does Gaia support CSRD reporting?
Yes, from the Pro plan. Pro lists CSRD/ESRS E1 and UK SRS reporting along with PPN 006. Start-Up covers GHG Protocol and SECR reports only, so a firm with CSRD duties needs at least the £650 tier. UK SRS reporting sits in the same tier.
Can Gaia connect to Xero or QuickBooks?
Pro lists accounting integrations with Xero, QuickBooks and Sage, and Start-Up excludes them. Whether a connection pulls spend by category or something coarser is not described on the pricing page, so ask before relying on it. Start-Up users upload bills and fuel documents instead.
Where does Gaia host customer data?
The privacy policy says the Gaia carbon accounting platform is hosted on Amazon Web Services in the UK. The BNG Marketplace hosting is not stated. A Cyber Essentials Plus badge appears on the page, and no SOC 2 or ISO 27001 report is mentioned.
Does Gaia offer an API?
API access is listed on the Enterprise plan only, at £1,500 plus VAT per month, and Pro and Start-Up exclude it. The pages opened do not describe endpoints, rate limits or documentation, so check those before planning an integration. Enterprise also brings SSO with enforced MFA.
