Program Overview: What is ISSB Sustainability Disclosure Standards?
ISSB Sustainability Disclosure Standards is Edstellar's instructor-led program for finance, sustainability, and reporting teams preparing disclosures under IFRS S1 and S2. It covers the ISSB baseline, general requirements, climate-related disclosures, GHG data handling, and jurisdictional filing over six modules and 24 hours. Participants learn to produce investor-grade sustainability disclosures. It is built for teams facing mandatory sustainability reporting.
Training is hands-on from the first module. Participants draft S1 and S2 disclosures from realistic company data, build GHG inventories, and test disclosure controls in twelve guided labs. Instructors coach each team through materiality judgments, assurance readiness, and drafting technique, giving direct feedback on every disclosure draft. Modules progress from the ISSB baseline through S1, S2, data controls, and filing. It closes with a complete ISSB disclosure package capstone reviewed by the instructor.
Investors and regulators now demand sustainability disclosures they can compare and audit, and boilerplate ESG narratives no longer pass. Finance teams struggle because climate data lives outside financial controls and the standards are new. This program teaches your teams to disclose properly: measured, controlled, and aligned with the ISSB baseline their auditors and investors expect.
The capstone is a full ISSB disclosure package for the scenario company: S1 general disclosures, S2 climate disclosures, GHG data with controls documentation, and an assurance-readiness assessment, defended in a review with the instructor. Your reporters return with drafted disclosures and the control craft to repeat the cycle every reporting year.
Across six modules and 24 hours, your team moves from the ISSB standard-setting landscape to a finished disclosure package. Every module pairs instruction with a guided lab, so each technique is practiced on realistic reporting data. It closes with a capstone your team designs, documents, and presents.

Connect ISSB Disclosure Narratives With Measured Data and Reviewable Evidence
Edstellar develops sustainability disclosure skills through S1 and S2 drafting and data-control exercises. Participants examine materiality, build emissions inventories, and trace metrics into supporting evidence. The final disclosure package brings narrative and calculations together, with feedback on completeness, data quality, consistency, and the jurisdictional assumptions used to frame reporting decisions.
- Step 01
Consult
We explore sustainability and financial reporting familiarity, source-data gaps, and difficulties with materiality or metric tie-outs to identify the cohort's ISSB disclosure development needs.
- Step 02
Plan
We establish the ISSB baseline before S1 governance and strategy and S2 climate requirements, then connect GHG calculations, disclosure controls, and assurance evidence in the package.
- Step 03
Align
We align sustainability reporting expertise with ESG, finance, risk, and operations roles, confirming available learning datasets and the jurisdictional context used for filing discussions.
- Step 04
Customize
We adapt sample issuer profiles and activity records to familiar industries, retaining missing metrics and uneven source quality that participants must resolve or explain.
- Step 05
Execute
Participants draft disclosures, calculate Scope 1 and 2 inventories, and defend metric tie-outs, receiving feedback on materiality reasoning, data quality, and consistency across the package.
- Step 06
Evaluate
We assess the disclosure package for supported S1 and S2 content, traceable calculations, documented materiality judgments, and evidence that clearly explains assumptions and remaining reporting gaps.
