Materiality Assessment for Indian Listed Entities — GRI 3 + ESRS 1 + IFRS S1 + AA1000 mapped to BRSR

Materiality assessment is the foundation underneath every credible ESG disclosure. For Indian listed entities filing BRSR, it determines what gets disclosed in Section A’s material-issues table, what depth each Principle narrative receives, which BRSR Core attributes get focused governance attention, and — under SEBI’s March 2025 amendment — what falls inside the value-chain ESG scope. This page sets out the methodology in the form Indian audit committees and BRSR assurance practitioners increasingly expect to see.

Why materiality assessment is the upstream choice

Every ESG disclosure decision flows from materiality. Skip the assessment, or do it badly, and three things break in sequence: the disclosure scope becomes either too narrow (regulator and investor queries follow) or too broad (preparation burden balloons, signal-to-noise collapses); the assurance practitioner cannot give a clean opinion because there is no documented basis for what was included and what was left out; and stakeholder trust degrades because the disclosure reads as a generic ESG report rather than a substantive account of the entity’s actual sustainability profile.

The same assessment also feeds the climate-transition-plan baseline, the human-rights due-diligence scope, the value-chain-engagement priority list, and the executive-remuneration-linkage selection. Getting it right at the top compounds downstream.

The three materiality lenses

Three globally recognised lenses dominate practice. An Indian listed entity must choose one (or apply more than one in parallel) before designing the assessment.

Lens	Standard	What is material	Perspective	When to use
Impact materiality	GRI 3: Material Topics 2021	The entity’s most significant actual or potential impacts on the economy, environment and people, including human rights	Inside-out (entity → world)	Default for BRSR; required if filing GRI; baseline for impact-led entities
Financial materiality	IFRS S1 (ISSB)	Sustainability-related risks and opportunities that could reasonably be expected to affect cash flows, access to finance or cost of capital	Outside-in (world → entity)	Required for IFRS-S1-jurisdiction filings (UK, Canada, Australia, 20+ others adopting); investor-led entities
Double materiality	ESRS 1 (CSRD)	Both impact AND financial, with explicit consideration of interdependencies	Both directions	Required for CSRD-in-scope entities (including non-EU groups with EU operations meeting thresholds); the convergent practice

The lenses are not interchangeable. A topic that is impact-material may not be financial-material (e.g. severe but localised human-rights violation in a small upstream supplier); a topic that is financial-material may not be impact-material (e.g. short-term cost-of-capital effect from a transition policy that does not in itself reduce the entity’s own impact). Indian listed entities with cross-border exposure typically run double materiality to satisfy the highest-bar regulator.

How GRI 3 frames impact materiality

GRI 3 (effective 1 January 2023, replacing GRI 101’s earlier materiality construct) defines material topics as those representing the organisation’s most significant impacts on the economy, environment and people — a deliberate shift from the previous stakeholder-interest-led definition. The four-step process: (1) understand the organisation’s context; (2) identify actual and potential impacts; (3) assess the significance of the impacts; (4) prioritise the most significant. Stakeholder engagement is one input into impact identification and significance assessment — but stakeholder views do not, on their own, determine materiality. The assessment is impact-led, not stakeholder-perception-led.

How ESRS 1 frames double materiality

ESRS 1 (Commission Delegated Regulation (EU) 2023/2772) requires both impact and financial materiality to be assessed together. The 2025 EFRAG simplification (still in finalisation as of May 2026) moves the default approach from checklist-heavy bottom-up to a strategic top-down assessment — starting from sustainability matters and assessing each for materiality, with bottom-up IRO aggregation permitted as an alternative. The disclosure requirement IRO-1 in ESRS 2 requires the entity to disclose its assessment process. Qualitative analysis is sufficient where the conclusion is clear; quantitative thresholds are not mandated. Interdependencies between impact and financial materiality must be considered (e.g. a long-term impact often becomes a financial risk once policy or stakeholder response catches up).

How IFRS S1 frames financial materiality

IFRS S1 (effective for annual reporting periods beginning on or after 1 January 2024) takes a single financial-materiality lens — sustainability matters in scope are those that could reasonably be expected to affect the entity’s cash flows, access to finance or cost of capital over short, medium or long term. The starting point is the same as financial-statement materiality but extended through the cash-flow lens to long-horizon sustainability risks. Twenty-plus jurisdictions (representing over half of global GDP) have adopted or are adopting IFRS S1; UK, Canada, and Australia are aligning their domestic sustainability frameworks. For Indian listed entities with listings or material operations in these jurisdictions, IFRS S1 financial-materiality is the operative test.

How BRSR fits the global lenses

SEBI’s BRSR does not formally prescribe a materiality lens. In practice, BRSR Section A General Disclosures requires entities to disclose material ESG issues with rationale, risk-or-opportunity classification, financial implications, and adaptation/mitigation approach — combining elements of all three global lenses. SEBI’s design draws most heavily from GRI’s impact orientation but explicitly asks for financial implications (an IFRS-S1-style addition) and stakeholder rationale (an AA1000-style addition). ICAI’s Background Material on BRSR (Revised Edition 2024) confirms entities are free to choose GRI, ESRS, IFRS S1, or a custom approach so long as the result is documented and defensible.

The BRSR Core attributes (the nine SEBI-mandated quantitative attributes subject to assessment or assurance) are pre-selected by SEBI based on a sectoral materiality view; entities do not re-perform materiality on the Core attribute set. The materiality assessment instead determines (a) Section A material-issues disclosure, (b) the depth of each Principle-wise narrative in Section C, (c) which voluntary Leadership Indicators the entity addresses, and (d) the value-chain ESG scope under SEBI’s March 2025 amendment. The March 2025 circular also materially eased value-chain ESG requirements: value-chain partners are defined as those individually contributing 2% or more of total purchases or sales by value (with the entity able to limit disclosure to cover 75% of purchases and sales); value-chain ESG disclosures (for the top 250 listed entities by market capitalisation) are voluntary from FY 2025-26; and assessment or assurance of those value-chain disclosures is voluntary from FY 2026-27. For the BRSR Core itself, assessment or assurance applies to the top 500 listed entities (by market capitalisation) for FY 2025-26 and extends to the top 1,000 from FY 2026-27.

The stakeholder-engagement layer — AA1000SES

The AA1000 Stakeholder Engagement Standard (2015 version current; revision underway 2025-2026) is the global benchmark for how engagement that informs materiality is conducted. It does not say what is material; it says how the engagement should be done. Three principles: inclusivity (commitment to engage and be accountable to those affected), materiality (determining the relevance and significance of issues), responsiveness (responding to stakeholder concerns in ways that affect performance). The standard is process-oriented and complements GRI / ESRS / IFRS S1 rather than competing with them. BRSR Principle 4 (stakeholder engagement) narrative is the natural disclosure home for AA1000SES alignment; explicit citation in the BRSR narrative materially increases the assurance practitioner’s confidence in the materiality output, because the engagement now has a recognised standard against which to test.

The six-step methodology applied to an Indian listed entity

Consistent across GRI 3, EFRAG IG 1, ICAI’s BRSR Background Material, and observed Indian listed-entity practice.

Step 1 — Understand the context. Document the business model, value chain (upstream + own operations + downstream), geographies of operation, sustainability landscape (regulatory, policy, sectoral), peer benchmark of disclosed material topics. For Indian listed entities, the context layer also captures: BRSR filing applicability (top 1,000 listed entities by market capitalisation); BRSR Core assessment-or-assurance phasing (top 500 from FY 2025-26, extending to top 1,000 from FY 2026-27 per the March 2025 SEBI circular); value-chain ESG voluntary applicability (top 250 listed entities from FY 2025-26, with voluntary assessment or assurance from FY 2026-27); value-chain partner 2%-threshold mapping; and any cross-border exposure that triggers CSRD or IFRS S1.

Step 2 — Identify IROs. Compile a long list of actual and potential impacts, risks and opportunities — environmental (climate, water, biodiversity, waste, pollution), social (labour, human rights, community, customer, supplier), governance (ethics, anti-corruption, board, executive remuneration, data privacy under DPDP Act 2023, AI governance per ICAI guidance + SEBI’s June 2025 AI/ML consultation paper as forward-looking signal for securities-market entities). EFRAG IG 1 permits both top-down (start from sustainability matters list) and bottom-up (start from incident-level IROs); both are valid.

Step 3 — Engage stakeholders. Internal (board, management, employees, employee representatives) and external (institutional + retail investors, lender groups, key customers, key suppliers, community in operating geographies, civil society / NGO bodies in scope of operations, regulators, sectoral associations). Methodology should follow AA1000SES inclusivity + responsiveness principles. Document invitations, response rates, methods (surveys, interviews, workshops, public consultations), and a summary of input received. For listed entities under BRSR Principle 4 disclosure, this documentation also feeds the narrative.

Step 4 — Assess significance. For impact materiality (GRI / ESRS): severity (scale + scope + irremediability) and, for potential impacts, likelihood. Severity weighs heaviest. For financial materiality (IFRS S1 / ESRS financial leg): magnitude of financial effect, likelihood, time horizon (short / medium / long). Document the scoring criteria — qualitative scales (high / medium / low) are permitted, quantitative thresholds (percentage of revenue, absolute INR magnitude) strengthen the assurance evidence base.

Step 5 — Prioritise and validate. Set a threshold separating material from non-material; document the rationale for the threshold. Validate the resulting material-topics list with management and the board (or designated board committee). Most Indian listed-entity BRSR submissions disclose 8 to 15 material topics; lists above 25 typically signal a confusion between relevance and materiality.

Step 6 — Disclose, monitor, refresh. Disclose the material topics and the assessment process per the chosen framework (Section A for BRSR; Section 3 of GRI 3 + topic-specific Standards for GRI; Disclosure Requirement IRO-1 in ESRS 2 + sustainability statement for ESRS; relevant IFRS S1 disclosures for IFRS). Monitor for triggers (acquisition, divestment, geography entry, regulation change, incident) requiring re-assessment. Refresh the full assessment on a defined cadence — typically every 2 to 3 years.

Evidence the assurance practitioner expects

For BRSR Core reasonable assurance under SAE 3000 (Revised), and for the new ‘assessment’ alternative pathway introduced by SEBI’s March 2025 circular for value-chain disclosures, the practitioner tests the process more than the conclusion. The evidence universe:

• Process documentation — written methodology, scope definition, IRO inventory, scoring criteria, threshold rationale
• Stakeholder engagement records — invitation lists, response data, consultation summaries (raw transcripts where available), response-rate analysis showing AA1000SES inclusivity
• Governance approval — board or committee minutes evidencing approval of the material topics list and the methodology, with dated record
• Disclosure linkage — explicit mapping from each material topic to specific BRSR (or GRI / ESRS / IFRS S1) disclosures, with no orphan disclosures (topic disclosed without being on the material list) and no orphan material topics (topic on the list without corresponding disclosure)
• Refresh history — date of last refresh, summary of changes from prior refresh, list of triggers monitored

A materiality assessment that has been independently assured under SAE 3000 (Revised) or ISAE 3000 (Revised) — most commonly as part of broader BRSR Core reasonable assurance or CSRD limited assurance — carries materially higher signal than an unassured assessment.

Common errors observed in Indian listed-entity practice

Five recurring errors that surface in BRSR submission reviews and BRSR Core assurance engagements.

1. One-off rather than refreshed. Assessment performed at first BRSR filing and never refreshed; topics list stale relative to current business and regulatory context. AA1000SES revision (in progress 2025-2026), DPDP Act 2023 enforcement maturation, EU AI Act phased rollout, and SEBI’s March 2025 value-chain amendment have all materially changed the relevant IRO landscape since first-filing entities did their original assessment.

2. Engagement confined to investors and customers. Missing community, NGO, employee-representative, and value-chain-supplier voice. Weakens both the impact-materiality lens (which requires impact-affected stakeholders) and AA1000SES inclusivity alignment. Indian context typically requires explicit community engagement in operating geographies, particularly where the entity has Principle 8 (inclusive growth) exposure.

3. No documented thresholds or scoring. Material topics listed without an audit-trail explanation of why they crossed the threshold; the practitioner cannot test the methodology because there is no methodology to test. The fix is to write down the scoring scale (even a qualitative high/medium/low) and the threshold rule (e.g. ‘topics scoring high on either severity or financial magnitude, or medium on both, are material’), before scoring begins.

4. Confusing relevance with materiality. Listing every topic the entity touches as material, defeating the prioritisation purpose. Standard practice anchors at 8 to 15 material topics for a typical Indian listed entity; lists above 25 typically indicate the threshold is set too low or the scoring exercise has not been validated.

5. Single-lens application where double is needed. For Indian listed entities with EU subsidiary exposure that triggers CSRD scoping, or with US / UK listings or material operations in IFRS-S1-adopting jurisdictions, single-lens (impact-only or financial-only) assessment fails the highest-bar regulatory test. Double materiality is the convergent practice for cross-border-listed Indian entities; running it once and disclosing under each framework’s structure is materially cheaper than running parallel single-lens assessments.

How BatchWise approaches materiality assessment as a service

BatchWise does not perform the materiality assessment itself — it coordinates the assigned partner CA firm (for BRSR Core Assurance engagements) or partner ESG consultancy (for stand-alone materiality engagements) who performs the work and signs the methodology memo. BatchWise contributes (a) the workspace and document architecture, (b) the stakeholder-engagement template library (AA1000SES-aligned), (c) the scoring template and threshold-decision support, and (d) the linkage matrix that maps material topics to specific BRSR / GRI / ESRS / IFRS S1 disclosures. The partner firm takes professional responsibility for the methodology and the conclusion.

For listed entities preparing for BRSR Core Assurance, the materiality assessment is typically refreshed in the preparation phase (Phase 1 of the BRSR Core Assurance methodology) so the assurance practitioner has a current, documented, and board-approved material-topics list to anchor the engagement against. Skipping this preparation routinely adds days to the assurance timeline and material qualifications to the opinion.
