Disclosure is phased in over three years by tranche; once commenced, the entity keeps reporting each financial year (an entity reporting on a calendar year aligns commencement with that annual report). An entity may disclose early, ahead of its tranche. More complex criteria, such as scenario analysis, financial effects and, for some entities, financed emissions, are sequenced into the second and third years, and entities may voluntarily report beyond the current year's requirements.
