Navigating the ISSB Climate Disclosure Standards: Compliance Strategies for UK & Global Businesses

Introduction

The International Sustainability Standards Board (ISSB) introduced its first global climate-related disclosure standards (IFRS S1 & S2) in 2023, pushing businesses to meet stricter climate risk reporting requirements.

These standards represent a shift toward standardised, investor-focused ESG disclosures aligned with TCFD recommendations and other global frameworks. The UK Government has confirmed that ISSB standards will form the basis for mandatory sustainability reporting for UK-listed companies, increasing compliance risks for businesses that fail to align. Regulators, including the FCA, are also intensifying efforts to address ESG misreporting and greenwashing.

This session will provide a clear breakdown of the ISSB standards, their impact on reporting obligations, and practical compliance steps for businesses, including how to align existing frameworks with ISSB standards, the risks of non-compliance, and strategies for preparing ISSB-aligned disclosures.
