What Good ESG Data Governance Looks Like

Every BRSR filing implies a level of data rigor that the underlying process rarely has, with numbers pulled together each year from disconnected spreadsheets and department heads who rarely speak to each other about sustainability data.

As assurance and assessment requirements tighten and BRSR Core phasing extends to a wider set of companies, the gap between what a report claims and how the underlying data was actually governed is becoming harder to hide.

Good ESG data governance is a specific, buildable discipline, and most Indian companies are still doing ESG reporting without it.

For many companies, ESG data collection remains an annual scramble led by the sustainability or CSR team, pulling numbers from HR, facilities, procurement, and plant-level teams with little standardization in how those numbers are defined or calculated. Two factories under the same company can report the same metric using different formulas, and no one notices until an auditor asks.

This gap traces to how ESG reporting entered Indian companies in the first place. BRSR is a relatively recent mandate, and for years before it, sustainability reporting was voluntary and treated as a disclosure exercise rather than a data function. Finance teams built decades of controls, reconciliation processes, and audit trails around financial numbers. ESG data never went through that same maturation, because until recently, nobody outside the company was checking closely.

That is now changing. Assurance and assessment requirements are tightening, BRSR Core is phasing in for progressively smaller companies, and lenders and investors increasingly pull ESG data directly into credit and investment decisions rather than treating it as background context.

Good ESG data governance is a specific, learnable discipline, not a byproduct of good intentions or a strong sustainability team. It requires the same ownership, consistency, and documentation that finance functions have applied to financial reporting for decades.

Companies that build this discipline now will face BRSR Core's expanding scope and tightening assurance standards from a position of readiness rather than scramble.
