Focus: A comprehensive guide to the ongoing effort to standardize global sustainability reporting, focusing on the merger and transition of major frameworks.

Key Points:

• ISSB and IFRS S1/S2: Detailed explanation of the International Sustainability Standards Board (ISSB) and its core standards, and their goal of creating a global baseline.

• The Double Materiality Principle: Contrasting "financial materiality" (risk to the company) with "impact materiality" (risk from the company on people/planet), and its role in European regulations (e.g., CSRD).

• Mandatory vs. Voluntary: Charting the global shift from voluntary standards (like GRI) to mandatory reporting regimes.

• Implications for Practitioners: Practical steps companies need to take to align their current reporting with the converging global standards.
