ISSB S1 S2 Integration Masterclass: Confident ESG Reporting for 2026

ESG Reporting Strategy for ISSB S1 S2

In 2026, the global ESG reporting landscape is converging—and ISSB S1 and S2 are now emerging as the global baseline for sustainability disclosures. For companies operating across jurisdictions, aligning with the ISSB’s IFRS Sustainability Standards is no longer optional. It’s becoming the default expectation from investors, regulators, and financial markets. Adopting these standards is essential not just for compliance, but for building stakeholder trust, accessing capital, and managing climate-related risks credibly.

This highly practical 3-hour masterclass is designed to equip cross-sector leaders, ESG professionals, sustainability officers, consultants, and finance teams with a comprehensive understanding of the ISSB’s IFRS S1 (General Sustainability Disclosure Requirements) and S2 (Climate-Related Disclosure Requirements). Participants will also learn how to map and reconcile these frameworks with regional disclosure regimes like the EU’s CSRD, the U.S. SEC Climate Disclosure Rule, and SASB sector-specific metrics.

Why ISSB S1/S2 Matters Now

Over 140 jurisdictions worldwide are expected to adopt or align with the ISSB framework, including major economies across Europe, Asia, the GCC, and the Americas. This shift demands that companies move from fragmented, voluntary ESG disclosures to standardized, investor-grade sustainability reporting.

The ISSB builds on existing frameworks like TCFD and SASB, but pushes companies further — requiring rigorous disclosures on Scope 3 emissions, scenario analysis, governance structures, and financial implications of sustainability risks and opportunities.

In particular, Scope 3 emissions (value chain emissions) have moved into the spotlight as they often make up the majority of a company’s carbon footprint. Scenario analysis, once a niche climate tool, is now an expected practice for understanding transition and physical risks.

In this masterclass, participants will go beyond theory to learn how to operationalise the ISSB standards, structure reporting processes, select meaningful KPIs, and communicate sustainability-linked financial data in a way that satisfies both compliance and investor scrutiny.

CorpStage masterclasses are led by global ESG reporting experts and senior sustainability practitioners who have advised listed companies and regulators. Our facilitators blend deep technical knowledge with real-world implementation insights, ensuring participants receive guidance that is both globally informed and locally actionable.

Whether you’re reporting for the first time or aligning multiple frameworks, this course provides a strategic, step-by-step path to implementation, helping you future-proof your ESG disclosures. Explore more self paced courses here
