BRSR Reporting in India: Full Compliance Guide for Listed Companies
India’s sustainability reporting landscape changed permanently on the day SEBI mandated BRSR for the country’s top 1,000 listed companies. Four years into that mandate, one pattern has become impossible to ignore: companies that treat BRSR as a compliance task produce reports that satisfy a regulator. Companies that treat it as a governance discipline produce reports that attract capital, reduce risk, and set the agenda in their sector.
This document is written for CFOs, Company Secretaries, Heads of Sustainability, and Audit Committee members who want to understand not just what BRSR requires, but what separates a credible, investor-ready BRSR report from one that merely fills pages in an Annual Report.
What Is BRSR and Why It Is Not the Same as the Old BRR
The Business Responsibility and Sustainability Report (BRSR) was notified by SEBI in May 2021 and replaced the earlier Business Responsibility Report (BRR). The shift was substantive, not cosmetic. Where the BRR asked companies to describe their policies, BRSR demands quantitative performance data – numbers that can be tracked, trended, compared, and assured.
BRSR is grounded in the National Guidelines on Responsible Business Conduct (NGRBC), issued by the Ministry of Corporate Affairs, which define nine principles of responsible business. Every listed company in the top 1,000 by market capitalisation on BSE and NSE must now disclose how their business performs and not just how it is governed against each of those nine principles.
The nine NGRBC principles cover ethics and transparency (P1), sustainable products and services (P2), employee well-being (P3), stakeholder responsiveness (P4), human rights (P5), environmental stewardship (P6), responsible policy advocacy (P7), inclusive growth (P8), and consumer responsibility (P9). Together, they map onto the three pillars of ESG – environmental, social, and governance making BRSR India’s most comprehensive ESG disclosure framework to date.
Who Must File BRSR and What the Phased Expansion Means
BRSR became mandatory for the top 1,000 listed entities by market capitalisation beginning FY 2022-23. The applicability is assessed at the end of the calendar year i.e., 31 December on the basis of average market capitalisation from 1 July to 31 December, so boards must monitor whether their company is approaching or crossing this threshold. Voluntary adoption is encouraged for companies beyond the top 1,000, and those who begin early are materially better positioned when the mandate reaches them.
More significantly, SEBI has been deliberate about expanding BRSR’s scope in phases. BRSR Core – a defined subset of BRSR indicators within BRSR is applicable to all companies preparing BRSR. External assurance of BRSR Core, however, has been mandated in a phased manner: for the top 150 listed companies from FY 2023-24, expanding to the top 250 from FY 2024-25, the top 500 from FY 2025-26 and the top 1000 from FY 2026-27. This phased architecture is SEBI’s clearest signal that BRSR is not a one-time disclosure event. It is a permanent, deepening feature of India’s capital market governance.
For companies that are not yet in the top 1,000 but are growing toward that threshold, voluntary BRSR adoption is not just a goodwill gesture. It is a head start on data infrastructure, governance processes, and stakeholder communication that cannot be built overnight. Pierag’s ESG & Sustainability Reporting and Assurance practice works with organisations at every stage of this readiness journey, from first-time voluntary reporters to companies already preparing BRSR and those mandated to undergo assurance requirements.
The Structure of BRSR: What the Three Sections Actually Require
BRSR is divided into three sections, and understanding their purpose is essential to preparing a disclosure that functions as more than a regulatory filing.
Section A – General Disclosures covers the company’s identity and basic profile. It includes details of business activities, product and service categories, locations of plants and offices, employee and worker headcount (permanent and contractual, disaggregated by gender), and the structure of holding, subsidiary, and associate entities. It also requires disclosure of CSR obligations, whether the company has met its prescribed CSR spending for the year, and the company’s grievance redressal mechanism.
Section B – Management and Process Disclosures is where governance is documented. For each of the nine NGRBC principles, the company must disclose whether it has a policy in place, identify who governs that policy (including Board-level oversight), and confirm whether the policy extends to the value chain. This section forms the foundation on which the credibility of Section C rests. Weak governance disclosures in Section B undermine even the most robust data presented in Section C.
Section C – Principle-wise Performance Disclosures is the engine of BRSR. For each principle, companies must report against two categories of indicators: Essential Indicators (mandatory) and Leadership Indicators (voluntary, but increasingly expected by ESG rating agencies and institutional investors). The Essential Indicators alone span a wide range of quantitative metrics, including greenhouse gas emissions, water and energy usage , waste management practices, employee wellbeing and safety measures, gender diversity, pay ratios, CSR programme outcomes, fairness in customer and supplier engagement, among others.
The credibility of Section C depends almost entirely on the data infrastructure a company has built. Companies that lack systems for tracking Scope 1 and 2 GHG emissions at facility level, or that do not maintain disaggregated workforce safety data, will discover these gaps during disclosure preparation often under filing pressure, when there is no time to address them properly.
BRSR Core: The Assurance Mandate That Changes Everything
In July 2023, SEBI introduced BRSR Core, with which the BRSR framework has been further strenghthened.
BRSR Core identifies a subset of Key Performance Indicators (KPIs) that are subject to mandatory assurance by an independent third party. The KPI set spans nine ESG attributes: GHG footprint, water footprint, energy footprint , embracing circularity – details related to waste management by the entity, enhancing employee wellbeing and safety, enabling gender diversity in business, enabling inclusive development, fairness in engaging with customers and suppliers, open-ness of business. In addition, companies are required to assess ESG performance across a defined portion of their upstream and downstream value chain; however, external assurance of value chain disclosures remain voluntary rather than mandatory.
Assurance is a high bar compared to self‑certification. It means the assurance provider must gather sufficient and appropriate evidence to conclude positively that the reported data is free from material misstatement. Self-certification or management attestation does not satisfy this requirement.
This matters for several practical reasons. First, the data underpinning BRSR Core KPIs must be generated by systems that have been designed for external validation. Ad hoc spreadsheet aggregation across business units will not hold up under third-party scrutiny. Second, the internal controls over that data must be documented and tested. Third, material discrepancies between assurance findings and reported figures create regulatory exposure.
Organisations preparing for BRSR Core assurance need a reporting and verification partner who understands both the sustainability framework and the assurance standards. Pierag’s ESG & Sustainability Reporting and Assurance practice is built specifically for this level of rigor. Our team includes professionals from diverse backgrounds – Chartered Accountants, Company Secretaries, Engineers, Environmentalists, Lawyers and specialists with advanced qualifications such as Masters in Sustainability, DipIFR (ACCA,UK), and certifications as GHG Accounting Lead Verifiers under ISO 14064.
The Five Compliance Gaps That Derail Most BRSR Filings
Having worked across listed companies at different stages of BRSR readiness, five failure patterns appear with regularity.
Gap 1: No system for Scope 1 and Scope 2 GHG data. Principle 6 under BRSR requires GHG emissions disclosure, and BRSR Core mandates its assurance. Most companies discover they have utility bills but no standardised protocol for converting them into CO2e figures across business units, fuels, and refrigerants. Building a GHG inventory aligned with a recognised framework (such as the GHG Protocol, ISO 14064, or IPCC Guidelines) takes time and requires clear methodology decisions that should not be made under time pressure.
Gap 2: Value chain blindspots. BRSR requires companies to assess the ESG performance of their upstream and downstream value chain specifically the top suppliers and customers by purchase and sales value. For most Indian manufacturers and service companies, this means engaging counterparties who have never been asked sustainability questions before. Companies that begin the value chain engagement 12 to 18 months early are far better positioned than those who attempt it in the quarter the report is due.
Gap 3: Workforce data that cannot be disaggregated. BRSR requires headcount, turnover, employee wellbeing measures, training participation, and pay data to be broken down by gender, permanent and contractual status, and often by category of employees and worker. HR systems that were not designed with BRSR in mind frequently cannot produce this disaggregation without significant manual effort, which introduces error and is difficult to assure.
Gap 4: Prior-year inconsistencies. BRSR requires prior-year comparatives for most quantitative metrics. Companies that change their data collection methodology over the years – or that simply did not collect certain data points in prior years – face the uncomfortable choice between restating figures or disclosing gaps. Neither option is cost-free from a credibility standpoint, as both raise questions about data reliability and governance maturity.
Gap 5: Fragmented ownership of ESG reporting. BRSR preparation requires data from diverse functions such as Company Secretary, HR, Finance, Operations, Utilities, Marketing, and CSR, among others. When ESG reporting is treated as a siloed exercise led by a single department, the result is incomplete or fragile data. Effective governance demands a coordinated, cross‑functional approach where each function owns its data and internal controls, while oversight is exercised at a higher governance level typically the Board, Audit Committee, or a designated ESG Governance Committee. Without this integration, assurance providers and ESG rating agencies quickly detect inconsistencies, undermining credibility.
BRSR and GHG Reporting: The Scope 3 Question
BRSR’s current mandatory scope for GHG reporting covers Scope 1 (direct emissions from owned or controlled sources) and Scope 2 (indirect emissions from purchased energy). Scope 3 emissions from the value chain, including purchased goods, employee commuting, waste, and the use of sold products is presently a Leadership Indicator and is not yet mandatory.
However, listed companies with global investors, export-oriented businesses, or supply chain partners in the EU are finding that Scope 3 is being asked for regardless of whether SEBI has mandated it. ESG rating agencies score it. Foreign portfolio investors’ questionnaires request it. The EU’s Carbon Border Adjustment Mechanism (CBAM) is making Scope 3 data commercially relevant for exporters of carbon-intensive products such as iron and steel, aluminium, cement, fertilisers, electricity, hydrogen, and related industrial products.
Companies that invest now in comprehensive GHG inventorisation including Scope 3 estimation are building an asset that serves BRSR and other global frameworks such as IFRS S2, CDP, and export compliance simultaneously. The earlier this work begins, the more reliable the baseline data becomes, and the more defensible the figures are when they eventually come under assurance scrutiny.
Technology-enabled data collection is increasingly central to scalability. Pierag’s Digital Support in ESG solutions help organisations automate emissions data capture, standardise reporting across facilities, and maintain the audit trails that assurance providers require.
The Investor and Capital Market Dimension
BRSR data is not filed in isolation . It directly shapes how institutional investors – domestic and foreign evaluate listed companies in India.
ESG rating agencies draw on BRSR disclosures to generate company scores. These scores influence index inclusion decisions, ESG fund allocations, and lending covenants attached to green bonds and sustainability-linked loans. A growing share of Indian institutional investors are allocating portions of their portfolios to entities with measurable ESG objectives, and that proportion is rising.
The quality of BRSR reporting is as important as the data itself. A report filed with missing Essential Indicators, absent prior-year comparatives, or internal inconsistencies between sections does not merely lower an ESG rating. It signals to sophisticated investors that the company’s governance culture does not extend to non-financial disclosure. Conversely, a report with independently assured or assessed BRSR Core data, comprehensive Section C disclosures, and clear year-on-year trends tells a story of operational discipline.
Access to sustainable finance in India – green bonds, sustainability-linked loans, ESG-themed equity is becoming materially easier for companies with credible, assured ESG disclosures. SEBI’s independent assurance mandate, RBI’s renewable energy priority sector classification, and International Capital Market Association (ICMA)-aligned frameworks are converging to make the quality of BRSR disclosures an increasingly important determinant of access to sustainable finance and the terms of capital.
CSR, BRSR, and the Governance Overlap
One area where BRSR compliance intersects with a separate regulatory requirement is CSR. CSR obligations under Section 135 of the Companies Act, 2013 apply to eligible companies, and BRSR Section A requires disclosure of whether these obligations are triggered. Principle 8 – inclusive growth and equitable development extends this further, requiring details of overall CSR projects, projects in aspirational districts, amount spent, beneficiaries (including vulnerable groups), Social Impact Assessment results, community grievance mechanisms etc..
Integrating CSR reporting with BRSR disclosures creates a coherent, evidence-backed narrative of social value creation. For companies whose CSR compliance is managed separately from their sustainability reporting function, this integration requires deliberate effort – and an honest audit of whether the programmes being funded are generating the kind of outcome data BRSR actually asks for.
Pierag’s CSR Advisory practice helps companies design, implement, and document CSR programmes that produce measurable impact, not just spending records, making Principle 8 disclosures a genuine reflection of community investment rather than a compliance entry.
Building an Assurance-Ready BRSR Programme: A Practical Roadmap
High‑quality BRSR reporting is not a once‑a‑year compliance exercise. Leading companies treat it as a year‑round discipline, embedding ESG data governance into everyday operations. The following staged roadmap reflects how organizations prepare for assurance with consistency and credibility:
Stage 1 – Gap Assessment: Conduct a structured review of current data against all BRSR Indicators. Identify data that does not exist, data that exists but cannot be disaggregated as BRSR requires, and data that exists but lacks the audit trail needed for assurance.
Stage 2 – Data Infrastructure Design: For each data gap identified, design the collection mechanism. This may involve integrating with ERP or HR systems, utility billing feeds, or establishing manual collection templates for facilities without automation. Document methodologies to support assurance. Technology investment at this stage delivers the highest return.
Stage 3 – Materiality Assessment: Conduct a formal materiality assessment to engage internal and external stakeholders to determine which ESG issues and KPIs are most relevant to the company’s business model, industry, and geography. Under BRSR, disclosure across all nine NGRBC principles and their Essential Indicators is mandatory; materiality instead guides the depth of reporting, the choice of voluntary Leadership Indicators, and the prioritisation of narrative emphasis in Section C. A documented materiality process ensures that disclosures are purposeful, evidence‑based, and aligned with stakeholder priorities, thereby enhancing the credibility of the overall report..
Stage 4 – Internal Controls and Governance: Assign clear ownership for each BRSR KPI to a designated function and accountable individual. Define and document the control activities such as review, reconciliation and approval that govern each metric. Engage the internal audit function to test a sample of these controls before the external assurance provider arrives.
Stage 5 – Report Preparation and Review: Draft the complete BRSR, ensuring figures are reconciled across all sections. Conduct a thorough cross-reference check against other regulatory filings, including Annual Report (with its financial statements), stock exchange disclosures, and the prior-year BRSR. Ensure that qualitative narratives in Sections A and B are consistent with quantitative data in Section C.
Stage 6 – Assurance: For companies requiring assurance of BRSR Core, engage the independent assurance provider well in advance of the filing deadline. Assurance engagements typically require 6 to 10 weeks, depending on the size and complexity of the company. Early engagement provides sufficient time to address any findings and implement corrective actions before the final report is published.
Stage 7 – Post-Filing Strategy Review: Use the completed BRSR as a structured input into the following year’s ESG strategy. Review KPIs that underperformed against internal targets or peer benchmarks, and set forward-looking commitments where disclosures exist without defined goals. Brief the Board and Audit Committee on findings and the improvement roadmap.
Building Internal Capability: The Role of ESG Education
One underestimated dimension of BRSR compliance is the gap between what boards and management teams are asked to govern and what they currently understand about ESG and sustainability reporting. Board members who review and approve the BRSR must be able to exercise genuine oversight not simply sign off on a document they cannot interrogate.
This is not just a training issue. It is a governance one. When board members and senior leaders lack fluency in GHG accounting, materiality assessment, or the difference between limited and reasonable assurance, decisions about what to disclose, how to interpret findings, and where to invest in sustainability infrastructure are made without the foundation they require.
Pierag’s ESG Learning Academy provides structured capacity-building programmes for boards, audit committees, sustainability teams, and finance functions. The programmes are delivered through structured ESG self‑paced learning modules, customised workshops, training and capacity‑building sessions, and on‑demand courses and webinars. For companies facing BRSR requirements, this literacy is not optional, it is a governance prerequisite.
Why Pierag: The CA and Assurance Angle
Most ESG advisory firms approach BRSR primarily as a reporting and communications exercise. Pierag approaches it as an assurance and governance discipline, and that distinction is consequential for listed companies whose disclosures face regulatory scrutiny and investor evaluation.
Our ESG and Sustainability practice is led by professionals from diverse backgrounds – Chartered Accountants, Company Secretaries, Engineers, Environmentalists, and Lawyers complemented by specialists with advanced qualifications such as Masters in Sustainabality, DipIFR (ACCA, UK), the ICAI Diploma in BRSR, and certifications as GHG Accounting Lead Verifiers under ISO 14064. Together, they bring deep experience in assurance engagements across large listed companies in India. We understand what an assurance provider will test because our team has performed those tests. We know what effective ESG data controls must look like because we have designed , reviewed , and reported on them.
This means that when we help a company prepare for BRSR Core assurance, we are not speculating about what the assurance provider may find. We are building the data infrastructure and governance controls that meet an independent, evidence-based standard – the same level of rigor applied in statutory financial audits.
Our broader ESG & Sustainability Services practice covers the full spectrum: sustainability reporting and assurance, GHG inventorisation, Life Cycle Assessment, ESG strategy, CSR advisory, digital ESG tools, and structured capacity building. Whether your organisation is filing its first BRSR or preparing for assurance of BRSR Core for the first time, we can help you move from reactive compliance to strategic ESG leadership.
Compliance Is the Floor. What You Build Above It Determines Value.
BRSR sets a minimum standard for what listed companies must disclose. It does not prescribe how well companies should perform against those disclosures, or how strategically they should use the discipline of reporting to improve their operations, governance, and stakeholder relationships.
The companies that will attract long-term institutional capital, access sustainable finance at competitive rates, and build trust with global supply chain partners are not the ones that merely file a compliant BRSR report. They are the ones that embed sustainability into performance measurement, risk management, and decision making and can demonstrate it through independently assured data.
BRSR makes that demonstration possible. What organisations choose to build above the compliance floor determines whether BRSR remains a cost of compliance or evolves into a source of competitive advantage.
