Why EcoLedger The problems we solve We do not know where to start ISSB guidance is dense, materiality takes time, and frameworks overlap confusingly. A guided workflow from setup to final report. GHG calculations are error-prone Scope 1, 2 and 3 factors change every year, and manual calculation risk grows over time. DEFRA and IEA factors matched to your reporting year. Industry-specific metrics are hard to pin down IFRS S2 expects industry-based metrics, which most teams struggle to identify for their sector. Industry-based metrics surfaced for your sector. Writing narratives takes weeks Drafting IFRS-quality disclosure text by hand is slow, and keeping it compliant is manual. The builder drafts IFRS-aligned narrative for you to edit. We cannot prove compliance Evidence is scattered, and linking disclosures to source documents is manual and fragile. An evidence register links every disclosure to its source. Advisory is expensive and recurring External ISSB advisory is costly and creates a dependency for every annual update. One annual licence, with the process owned in-house. Getting started Up and running in three steps 1 Purchase & open Buy your licence, get instant access, and open it in your browser.

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 ISSB reporting project with a consultant typically costs £15,000 to £25,000. EcoLedger is £3,900 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.
