2. BRSR Core: the nine attributes, with evidence ready for assessment or assurance. Ask: "For each Core attribute, what evidence sits behind the number?"
3. Collects data from value chain partners (2% or more of purchases or sales). Ask: "How do our partners send data, and what does it cost them?"
4. Scope 1 and 2 from activity data with Indian factors (CEA grid factor by year). Ask: "Which CEA grid factor version does it use for this financial year?"
5. Source document, factor and approver kept against each figure. Ask: "Click a figure: who approved it, and from which bill?"
6. Exchange XBRL output for filing. Ask: "Does it produce the exchange XBRL file?"
7. Reflects SEBI’s March 2025 changes. Ask: "Show us where it handles assessment versus assurance."
8. Price published on its site. Ask: "What will year one cost, all in?"
