FAQ

Frequently asked questions

Who should report under IFRS S1 and S2?

IFRS S1 and S2 are the ISSB's global baseline for sustainability and climate disclosure, being adopted jurisdiction by jurisdiction, with 20+ jurisdictions on board as of 2026. If you report on sustainability and climate, they are the framework investors increasingly expect.

Which emission factors are included?

DESNZ and IEA factors for Scope 1, 2 and 3, matched to your reporting year, with IEA grid factors for international operations. New factor editions are added each year and included with your licence.

How does this compare to hiring a consultant?

An initial ISSB reporting project with a consultant typically costs £15,000 to £25,000. EcoLedger is £7,900 for the reporting year, and you own the process and can repeat it each year.

Do I need sustainability expertise to use this?

No. The workflow is designed for finance and sustainability teams without prior experience, guiding you through each requirement with explanations, templates and help text throughout.

Can I use this for multiple entities?

Yes. The standard licence covers three entity profiles, each with its own metrics and disclosure set. Larger groups reporting across many subsidiaries are suited to our Enterprise and Group plans.

Where is my data stored, and is it secure?

You choose. Your data can stay entirely on your own computer, in your browser, or you can sign in to sync it securely and use EcoLedger from any device. Sign-in is passwordless, a single-use code sent to your email, your data is only ever transferred over an encrypted connection, on enterprise-grade hosting, and everything is exportable at any time.
