Materiality Assessment Walkthrough for BRSR

What materiality assessment is — and why it matters for BRSR

A materiality assessment is the process by which an entity identifies which sustainability topics are most relevant to its stakeholders and to its own operations, and prioritises those topics for disclosure and management focus. The output is typically a materiality matrix — a 2×2 plot of topics by importance to stakeholders (one axis) and importance to the entity (the other axis), with topics in the high-high quadrant treated as “material”.

For BRSR purposes, materiality assessment is not a discrete BRSR disclosure on its own. Instead, it underpins scope and applicability decisions across multiple Principles:

• Principle 6 (Environment) — Leadership indicator on Scope 3 GHG emissions asks for material Scope 3 categories; the materiality framework is what determines which of the 15 GHG Protocol Scope 3 categories are in scope
• Principle 5 (Human Rights) — Leadership indicator on value-chain partner assessment asks for material value-chain partners; materiality determines the in-scope partner population
• Principle 8 (Inclusive Growth) — Social Impact Assessment scope decisions reference the entity’s materiality framework
• Principle 4 (Stakeholder Engagement) — Essential indicators ask for the entity’s stakeholder identification and engagement framework, of which materiality assessment is a core element

The materiality assessment itself is not directly assured under the BRSR Core mandate. But the methodology behind specific assured numbers and applicability claims — particularly on the Leadership indicators above — is what the assurance partner reviews when challenging an entity’s “this is in scope” or “that is not material” call.

A documented, defensible materiality assessment is therefore the upstream input that makes downstream BRSR scope decisions audit-ready.

The four common methodology choices

There is no single SEBI-prescribed materiality framework for BRSR. Indian listed entities commonly apply one or a combination of the following:

Framework	Origin	Materiality lens	Best fit for
GRI 3 — Material Topics (2021)	Global Reporting Initiative	Impact materiality (entity’s effect on society / environment)	Broad sustainability-narrative reporting; the “double materiality” perspective
SASB Materiality Map	Sustainability Accounting Standards Board (now part of IFRS Foundation)	Financial materiality (effect on entity’s financial performance)	Sector-specific benchmarking; investor-facing disclosure
TCFD recommendations	Task Force on Climate-Related Financial Disclosures	Climate-financial materiality	Climate-specific risk and opportunity disclosure
Entity-specific hybrid	Internal	Entity-defined, often combining the above	Most Indian listed entities in practice

For Indian listed entities reporting under BRSR, common practice is a hybrid — GRI 3 for the broader sustainability narrative, SASB for sector-specific benchmarking, and a TCFD overlay for climate-related items. The entity discloses which framework it has applied and why.

The EU Corporate Sustainability Reporting Directive (CSRD) explicitly requires double materiality. For Indian entities with EU operations or EU customer reporting requirements, double materiality is the de facto standard — and the materiality assessment then needs to satisfy both the BRSR (principle-based, methodology-flexible) and the CSRD (double materiality required) frames.

Single materiality vs double materiality — the choice that matters

The biggest framework choice is whether the assessment captures single or double materiality:

• Single materiality — only how sustainability issues affect the entity (financial impact). Aligned with SASB and TCFD origin frameworks. Simpler to scope, narrower output.
• Double materiality — both how sustainability issues affect the entity (financial) AND how the entity’s activities affect society / the environment (impact). Aligned with GRI 3 and EU CSRD. Broader stakeholder engagement required, more topics typically classified material.

The BRSR format is principle-based and does not prescribe one approach over the other. In practice, Indian listed entities increasingly apply double materiality for the BRSR exercise — investor narrative leans on the financial-materiality view; broader stakeholder narrative draws on the impact-materiality view. The methodology section of the assessment should make the chosen approach explicit.

The five-step walkthrough

A typical BRSR-aligned materiality assessment runs through five stages. The exact mechanics vary by entity scale and complexity, but the structural arc is consistent.

Step 1 — Topic identification

Identify the universe of sustainability topics potentially relevant to the entity. Typical sources:

• The 9 NGRBC Principles as a baseline (every NGRBC Principle gets at least one topic)
• The full set of GRI 3 Material Topics standards
• The SASB Materiality Map for the entity’s sector(s)
• Topics raised in prior-year stakeholder consultations, investor letters, regulator communications
• Sector-specific topics (climate transition for energy, drug-pricing for pharma, financial inclusion for banking, etc.)
• Emerging topics flagged by ESG-rating agencies or international peers

The output of Step 1 is a long list — typically 30-50 topics, before prioritisation.

Step 2 — Stakeholder engagement

Engage the entity’s defined stakeholder groups (employees, customers, suppliers, investors, regulators, communities, civil society) to capture their views on which topics matter most and why. Common engagement mechanisms:

• Surveys (online, structured rating of topics)
• Focus groups (typically with employees and select community / civil society representatives)
• Investor / analyst calls covering ESG topics
• Regulator and standard-setter consultations (formal responses to public consultations)
• Customer feedback channels
• Vendor / value-chain partner consultations (where the entity has a structured supplier program)

The engagement basis (who was consulted, how, when) is a documented disclosure item under Principle 4. Stakeholder engagement evidence is what the assurance partner reviews when the entity claims a topic is or is not material.

Step 3 — Scoring and prioritisation

Score each topic on the chosen materiality dimension(s). For double materiality, this is two scores per topic:

• Importance to stakeholders (the impact-materiality / outside-in dimension) — typically scored on a structured framework drawing from the engagement responses in Step 2
• Importance to the entity (the financial-materiality / inside-out dimension) — typically scored against revenue exposure, regulatory exposure, brand exposure, operational exposure

The two scores produce the materiality matrix — topics in the high-high quadrant are “material”. The threshold for what counts as “high” is documented and applied consistently year-on-year.

Step 4 — Validation and approval

The materiality outcome is reviewed by:

• Internal sustainability / ESG committee — typically a board sub-committee or senior management committee
• External advisor — many entities engage a sustainability consultant or ESG-rating agency to provide a peer-benchmarked validation
• Audit committee — for material disclosures that cross into financial-materiality territory, the audit committee’s view is captured
• Board ratification — the final material-topics list is typically board-ratified to give the materiality framework appropriate governance backing

Step 5 — Disclosure and operational integration

The materiality outcome is disclosed in the BRSR (typically as a narrative with an accompanying matrix visualisation), referenced in the Annual Report’s Management Discussion and Analysis section, and operationally integrated through:

• Material topics that map to specific BRSR Core KPIs feed those KPI workpapers (Principle 6 environmental KPIs, Principle 3 employee KPIs)
• Material topics that affect Leadership indicator scope (Scope 3 categories, value-chain partner population, SIA scope) feed those applicability decisions
• Material topics drive next-cycle ESG strategy priorities and budget allocations

Output deliverables

A complete materiality assessment produces, at minimum:

Deliverable	Format	Audience
Materiality matrix	Visualisation (2×2 plot, sometimes heatmap)	BRSR Annual Report; investor presentations
Methodology note	Document	BRSR Annual Report; assurance partner
Stakeholder engagement record	Document	Internal governance; assurance partner on request
Material topics list with rationale	Table	BRSR Annual Report; integrated into operational planning
Year-on-year change log (after first cycle)	Document	Demonstrates refresh discipline; flagged in BRSR notes when changes affect prior-year comparability

The matrix is the most-cited public artefact; the methodology note is the most-scrutinised document by the assurance partner.

Refresh cadence

Common practice for Indian listed entities:

• Annual refresh — aligned to the BRSR reporting cycle, updates the prior-year matrix for new operations, M&A, regulatory developments, and emerging stakeholder concerns. Typically a few weeks of work
• Substantive re-base every 2-3 years — full stakeholder re-engagement, framework re-evaluation, fresh scoring. Typically a quarter-long exercise
• Interim refresh — triggered by material business changes (a major incident, a regulatory shift, a strategic pivot, large M&A). Documented with the trigger event

The refresh cadence applied should be disclosed alongside the materiality outcome. Cycle-on-cycle changes in material-topic classification should be flagged and the rationale disclosed — the assurance partner notices when topics quietly drop in or out without explanation.

Common pitfalls

Common practice patterns observed in BRSR engagements — not SEBI-recognised categories of finding:

1. Methodology framework undisclosed. The materiality matrix is presented without a clear statement of which framework (GRI / SASB / TCFD / hybrid) was applied. Both single vs double materiality framing should be explicit.
2. Stakeholder engagement evidence thin. The disclosure references “stakeholder consultation” without specifying which stakeholder groups, how many, what mechanism, and when. Engagement evidence is the foundation of the matrix.
3. Scoring rationale opaque. Topics are placed on the matrix without a documented scoring methodology. The threshold for “material” should be a documented, repeatable rule.
4. Year-on-year drift unexplained. Material topics quietly change between cycles without disclosure of the rationale. Cross-year comparability requires either consistent topic treatment or explicit change disclosure.
5. Scope mismatch with downstream BRSR disclosures. The materiality matrix lists topic X as material but the entity then makes an “X is not material to us” applicability claim on a Leadership indicator (or vice versa). The matrix and the downstream applicability calls should be consistent.
6. External validation absent for the first cycle. First-time materiality assessments without any external benchmarking (peer review, sector comparison, ESG-rating agency input) are easier to challenge as internally driven. External validation strengthens the documentation.

How this rolls into BRSR Core Assurance

The materiality assessment itself is not in the BRSR Core reasonable-assurance scope. But the methodology behind several Core KPIs and Leadership indicator scope decisions draws on the entity’s materiality framework. Specifically:

• Scope 3 GHG categories treated as “material” for the Principle 6 Leadership indicator should reconcile to the materiality assessment outcome
• Value-chain partner population for the Principle 5 Leadership indicator on partner assessment should be defined consistently with the materiality framework
• Smaller-towns / SIA / R&R scope decisions under Principle 8 reference the materiality of community impact
