Governance & disclosure
Mandatory Reporting
Definition
Mandatory reporting refers to legally binding obligations for companies to disclose environmental, social and governance information, imposed by statute or securities regulation — for example the EU Corporate Sustainability Reporting Directive (applying to companies above thresholds such as more than 1,000 employees and €450 million turnover under the 2026 amended scope), ISSB-standard adoption in various jurisdictions, and California's SB 253 and SB 261 climate disclosure laws.

Overview
What it means
The global landscape is shifting from voluntary frameworks (GRI, CDP, TCFD) toward regulated disclosure with assurance requirements, digital tagging and penalties for non-compliance — though scope and thresholds are politically contested and frequently revised.
How it is used
Compliance teams track which regimes apply by size, listing and geography; investors rely on mandatory disclosures as comparable, assured data for stewardship and risk pricing.
Why it matters
Mandatory regimes convert sustainability from reputation management into legal accountability, improving data quality and comparability — and making greenwashing legally risky. **Note:** In-batch merge: 1693 (mandatory ESG reporting) → this entry.
