If your company is in the top 1,000 listed entities by market cap, BRSR is not news to you. What may be news is how the bar has moved: assurance requirements that started with the top 150 companies are working their way down the list, and "reasonable assurance" means an auditor asking where each number came from.
The emissions disclosures that matter
BRSR's Principle 6 is where carbon lives. The core asks:
- Scope 1 emissions — direct emissions from fuel you burn, processes you run, refrigerants you leak. In tonnes of CO₂e, with the methodology stated.
- Scope 2 emissions — purchased electricity, calculated with grid emission factors. For India, that means CEA's factors, updated annually — using a three-year-old factor is a findable error.
- Intensity ratios — emissions per rupee of turnover, and increasingly per unit of physical output. These are the numbers analysts actually compare.
- Scope 3 (leadership indicators) — still voluntary for most, but customer questionnaires are making it commercially mandatory faster than SEBI is making it legally so.
Where companies get caught
Three failure patterns show up repeatedly:
- The estimate that became a fact. A consultant's one-time estimate gets copied forward year over year. When assurance arrives, there's no source data behind it — and restating emissions downward looks worse than never having reported.
- The missing fuel. Diesel gensets, company vehicles, LPG in canteens — Scope 1 sources that don't sit in the electricity bill folder and get forgotten until an auditor walks the site.
- The boundary problem. Subsidiaries, leased assets, and joint operations reported inconsistently between the financial statements and the BRSR. The two documents get read side by side.
What "audit-ready" actually means
An assurance provider will ask for the calculation trail: the bill or invoice, the extracted quantity, the emission factor applied, and the arithmetic. If your reporting process can produce that chain for any figure in under a minute, you're ready. If producing it means reopening last year's spreadsheet archaeology, you're not — and the time to fix that is before the reporting window, not during it.
The practical move: build the inventory from source documents once, with extraction and calculation automated, so every subsequent year is an update rather than an excavation.
