The problems we solve
We do not know where to start
ISSB guidance is dense, materiality takes time, and frameworks overlap confusingly.
GHG calculations are error-prone
Scope 1, 2 and 3 factors change every year, and manual calculation risk grows over time.
Industry-specific metrics are hard to pin down
IFRS S2 expects industry-based metrics, which most teams struggle to identify for their sector.
Writing narratives takes weeks
Drafting IFRS-quality disclosure text by hand is slow, and keeping it compliant is manual.
We cannot prove compliance
Evidence is scattered, and linking disclosures to source documents is manual and fragile.
Advisory is expensive and recurring
External ISSB advisory is costly and creates a dependency for every annual update.

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. They are being adopted jurisdiction by jurisdiction, with 21 jurisdictions on board as of 2026, some mandatory and some voluntary, and others such as the UK adopting their own versions. If you report on sustainability and climate, IFRS S1 and S2 are the framework investors increasingly expect.
Do I need sustainability expertise to use this?
No. The workflow is designed for finance and sustainability teams without prior ISSB experience, guiding you through each requirement with explanations and templates, and help text throughout.
Which emission factors are included?
DEFRA 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.
Can I use this for multiple entities?
Yes. You can set up multiple entity profiles within a single licence, each with its own metrics and disclosure set, which suits groups reporting on subsidiaries or consolidated scenarios.
How does this compare to hiring a consultant?
An initial ASRS reporting project with a consultant typically costs £15,000 to £25,000. EcoLedger is £5,900 for the reporting year, and you own the process and can repeat it each year. You can still use advisers for materiality or governance if you wish, but the heavy lifting is done for you.
Are future ISSB amendments included?
Yes. As the ISSB issues amendments or new standards, the tool is updated, and emission factors refresh automatically, included with your annual licence.
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.
