BRSR for Manufacturing Companies: Key ESG Metrics, Reporting Challenges, and Peer Benchmarking

28 April 2026 · 13 min read · By Credibl ESG

BRSR is one framework, but it isn’t one disclosure burden. A cement plant and a SaaS company file the same nine NGRBC principles. Only one of them deals with Scope 1 in millions of tonnes, water withdrawal across five stressed basins, and hazardous waste registers tied to Form 10 manifests.

If you’re a sustainability, finance, CS, or EHS lead at a listed manufacturer, you’ve inherited that load. This guide is a sector-specific read: the metrics that actually matter, where the data systems break first, and how peer benchmarking turns the filing into something useful.

One thing to anchor on before we start. Regulators, assurance providers, lenders, and global customers don’t read your BRSR uniformly. They go straight to a small set of fields. Know which ones.

Why BRSR is not one-size-fits-all (and why manufacturing carries a heavier disclosure load)

Same nine principles, very different stakes. A steel mill’s BRSR looks nothing like an NBFC’s, and definitely not like a SaaS company’s.

For manufacturers, the E pillar runs the show: fuel combustion, process emissions, water-heavy operations, effluents, hazardous and non-hazardous waste, raw material extraction, packaging, transport. The S and G pillars (OHS, supplier ethics, anti-bribery) are still there, but most of the disclosure volume and almost all of the assurance risk sit on the environmental side.

The data backs this up. BRSR Barometer studies covering 800-plus FY24 filings across 12 sectors show a clear pattern: in heavy-industrial cohorts (Power and Metals lead the pack), Scope 1 alone accounts for well over three-quarters of combined Scope 1 + Scope 2 emissions.

For a financial services firm in the same dataset, Scope 1 is essentially a rounding error. Same form, completely different stakes. That’s what shapes which principle an analyst reads first, which metrics ICRA and CRISIL weight, and which line items an ISAE 3000 / SAE 3000 provider digs hardest into.

Which BRSR principles matter most for manufacturers

Principle 6. Environment (the heaviest lift)

This is where the real disclosure burden lives. The list is long: energy by source and intensity per rupee of turnover; Scope 1 and Scope 2 emissions and intensity (per turnover, and per unit of physical output where required); water withdrawal by source (surface, groundwater, third party, seawater); consumption and discharge by destination and treatment level; withdrawal in water-stressed areas.

And that’s just the start. Add air emissions (NOx, SOx, PM, VOCs, POPs, HAPs); waste by category (plastic, e-waste, biomedical, construction, hazardous, non-hazardous), recovered and disposed; ZLD status; EIA compliance; and PAT participation under the BEE.

What’s new this year? FY26-27 pulls the top 1,000 listed entities into BRSR Core assessment or assurance for the first time. For manufacturers sitting in the 500–1,000 market-cap band, that’s a step-change. These numbers haven’t been through third-party scrutiny before.

And the methodology isn’t optional anymore. The Industry Standards on Reporting of BRSR Core (ISF: ASSOCHAM, FICCI, CII; December 2024) are now what auditors will hold you to for GHG, water, and waste calculations.

Principle 3. Employee wellbeing and occupational safety

This is the second concentration point. LTIFR, fatalities, near-miss reports, complaints on working conditions, training hours on health and safety, contract workforce coverage.

Site-level granularity matters here. Assurance providers will dig into plant-by-plant safety stats and reconcile them against your Factories Act and BOCW filings. Where do most numbers diverge? Contract workforce safety training. Almost every time.

Principle 2. Sustainable products and value chain

LCA coverage of significant products, percentage of recycled or reused input material, product reclamation, EPR compliance. Value chain ESG disclosures kick in from FY25-26 (voluntary for now), with assessment or assurance applicable from FY26-27.

The threshold matters. You have to report on upstream and downstream partners that individually account for 2% or more of purchases or sales by value. Or you can choose to limit aggregate disclosures to 75% of value.

For manufacturers with deep MSME supplier bases, this is where things break first. The data simply doesn’t exist in any structured form.

Principle 9. Consumer product responsibility

Product recalls, consumer complaints, advertising compliance, cybersecurity incidents (with CERT-In linkage). Mostly relevant for B2C manufacturers and pharma-adjacent players. For pure B2B industrial, it’s lighter, but never zero.

Principles 1, 4, 5, 7, 8, brief coverage

None of these are manufacturing-distinct on the face of the form. The exception is human rights and stakeholder engagement at plant communities, where operational disruption history (protests, land disputes, water-sharing conflicts) creates concrete disclosure content.

The BRSR metrics that actually move for a manufacturer

Out of 140-plus data points in a BRSR, a much smaller set carries most of the weight. Three buckets, and they get tested in this order:

The data challenges manufacturers will hit (and where they break)

Manufacturers don’t fail BRSR because they can’t read the regulation. They fail because the data refuses to behave the way the reporting form assumes it will. Here are the five places it breaks, in roughly the order you’ll hit them.

Peer benchmarking, turning BRSR from a compliance filing into a performance tool

Two years of public BRSR data (FY23, FY24) are now filed with the exchanges. FY25 is landing through 2025–26.

Comparing your energy intensity, water intensity, emission intensity, LTIFR, and waste recycling rates against your sector peers isn’t hypothetical anymore. Investors pulling ESG ratings, lenders pricing sustainability-linked loans, global B2B customers running Tier-1 supplier reviews. They’re all doing it. Are you?

Here’s where most manufacturers go wrong: they compare against “the sector.” Don’t. Sector averages hide everything that matters.

Draw the peer set tight: same product category, similar revenue band, comparable geography. A specialty chemicals company benchmarking against an aluminium smelter generates noise. The same company benchmarking against four other specialty chemicals peers in the ₹3,000–8,000 crore range generates signal.

And the gaps are already public. CSE’s Strengthening Environmental Reporting under BRSR (May 2024) reviewed 28 reports from 14 top companies and flagged the same things repeatedly: too much consolidated data hiding per-plant performance, almost no per-unit-of-output disclosure.

Prayas Energy Group’s review of the top 150 found at least six different unit conventions for energy and emissions in the same cohort. Manufacturers who clean their numbers first are the ones who come out looking good, before the industry catches up.

BRSR Core and assurance: what changes for top 1,000 manufacturers in FY26-27

The phasing is now in its fourth year. From FY26-27 (the current financial year), BRSR Core assessment or assurance extends to the top 1,000. That sweep covers most of the listed Indian manufacturing universe.

SEBI softened the language in December 2024: “reasonable assurance” became “assessment or assurance,” giving companies a lighter assessment route alongside full third-party assurance. Helpful, but don’t read it as relaxation. The data quality bar hasn’t moved.

If you’re entering scope this year, what does it mean in practice? Source documentation for every quantitative data point in BRSR Core. Calculation methodologies that are documented, version-controlled, and don’t quietly change year-on-year.

Internal controls over ESG data that start to look more like financial controls. The nine BRSR Core attributes (three environmental, four social, two governance) are where the testing starts.

The Industry Standards on Reporting of BRSR Core (ISF: ASSOCHAM, FICCI, CII; 20 December 2024) are now the operative methodology document. They standardise how GHG, water, waste, and energy intensity are calculated.

Intensity ratios are required in two forms: output-based, and PPP-adjusted revenue-based using the latest IMF PPP rate. Adopt these methodologies before assurance, not after the auditor flags it.

SEBI’s March 2025 circular pushed value chain ESG assessment to FY26-27, giving you a usable window. Use it.

How manufacturers should approach BRSR, a practical sequence

If you’re a sustainability or finance lead staring at a blank slate, here’s a workable order of operations. Five steps, in sequence, skip one and the next gets harder.

1. 1

   Reconcile against statutory filings

   EHS & Sustainability

   Map every BRSR Principle 6 data point to existing CPCB Form 3/4/10, BEE PAT, EIA approvals, and CTO/CTE filings. Fix mismatches now, before assurance flags them.

   Skip andAudit qualification on hazardous waste
2. 2

   Lock the reporting boundary

   Finance & CS

   Pick operational vs financial control under the GHG Protocol. Document which leased sites, JVs, contract manufacturers, and captive power plants are in scope. Don’t redraw the line year-on-year.

   DeliverableBoundary memo, board-approved

   Skip andYear-on-year intensity loses comparability
3. 3

   Build site-level data infrastructure

   IT + Sustainability

   Spreadsheets do not survive reasonable assurance or BRSR Core assessment. Move to a system with per-site data capture, version control, source-document linkage, and audit trails.

   DeliverableSingle ESG data platform across plants

   Skip and“Show me the audit trail” breaks the cycle
4. 4

   Run peer benchmarking

   Sustainability + Strategy

   Pick five sector peers in your revenue band. Pull their BRSR filings from NSE/BSE. Compare honestly on energy intensity, water intensity, GHG intensity, LTIFR, and waste recycling rates.

   DeliverablePeer-comparison scorecard, 5 metrics

   Skip andInvestors and lenders see the gap before you do
5. 5

   Convert gaps into internal targets

   Board & CXO

   Turn benchmark gaps into operational targets, not just better filing language. Tie each target to a BRSR Core attribute, an owner, and a timeline. Refresh annually.

   Skip andBRSR stays a filing exercise, not a strategy

The bottom line

BRSR isn’t a generic checklist for Indian manufacturers. The framework is uniform; the burden isn’t.

Manufacturers carry the heaviest environmental disclosure load, the highest assurance risk, and the most operationally complex data collection, all at the same time. That isn’t a problem to be wished away. It’s an opportunity.

The companies that build proper ESG data systems, reconcile against their own statutory filings, adopt the December 2024 Industry Standards methodologies, and benchmark honestly against tight peer sets will turn BRSR into operational intelligence. The kind that compounds over reporting cycles and that investors, lenders, and global customers actually notice.

The rest will keep filing.
