The problems we solve
ISSB guidance is complex. Materiality assessments take months. Reporting frameworks conflict.
Scope 1, 2 & 3 emission factors change yearly. Manual calculation risks increase year on year.
Drafting IFRS-quality disclosure text is time-consuming. Ensuring compliance is manual.
External advisory is expensive and creates ongoing dependency for every annual update.
Audit trail is fragmented. Linking disclosures to evidence is manual and error-prone.
Excel files, email trails, scattered spreadsheets — no single source of truth.
Built for every part of ISSB reporting
