In May 2021, the Securities and Exchange Board of India (SEBI) made a landmark move that changed the way Indian businesses disclose their non-financial performance. For the first time, the country’s top listed companies were required to prepare a Business Responsibility and Sustainability Report (BRSR), a detailed ESG disclosure framework designed to match global reporting standards like GRI and TCFD.

This requirement is for the top 1000 (representing more than 70% of India’s market capitalization), to mandatorily publish BRSR reports on the BSE and NSE portals.  The reports demand quantifiable data on emissions, energy usage, waste, human rights, employee diversity, tax transparency, and even the ESG practices of value chain partners. Businesses shouldn’t consider this as another regulatory burden, but as  a sign that capital markets, regulators, and global investors now judge Corporate performance through the ESG lens as much as through quarterly profits. 

Earlier Business Responsibility Report (BRR) asked companies to narrate CSR and ethical practices, but now BRSR makes them quantify, verify, and benchmark ESG outcomes. This transformation moves sustainability from the periphery of annual reports to the heart of corporate governance and risk management.

In this article, we provide a detailed exploration of the BRSR framework, its compliance requirements, the transition from BRR, and the best practices companies need to adopt to stay ahead.

Understanding Sustainability Reporting

Sustainability reporting is the practice of disclosing data on how a company manages environmental impacts, supports social responsibility, and maintains governance standards. Unlike financial reporting, which captures historical performance in monetary terms, sustainability reporting is multi-dimensional. It reflects how a business consumes resources, manages waste, safeguards employee well-being, ensures ethical governance, and plans for climate-related risks.

Globally, three frameworks dominate ESG reporting: 

1. GRI – Focused on broad sustainability disclosures across industries. 
2. SASB – Industry-specific standards that connect ESG with financial materiality. 
3. TCFD – Concentrated on climate-related risks and opportunities. 

BRSR integrates elements from all three but contextualizes them for India. For example, where TCFD emphasizes climate resilience, BRSR also accounts for inclusive growth, human rights, and national development priorities. 

The rationale for sustainability reporting is not only ethical but also financial. Studies consistently show that companies with strong ESG practices enjoy: 

• Lower cost of capital, 
• Enhanced investor confidence, 
• Better operational efficiency, and 
• Stronger stakeholder trust. 

Thus, sustainability reporting is increasingly seen as strategic value creation, not just regulatory compliance.

What is BRSR 

The Business Responsibility and Sustainability Report (BRSR) is SEBI’s mandatory ESG disclosure framework for the top 1,000 listed companies in India by market capitalization. Introduced in 2021 and made mandatory from FY 2022–23, it is built on nine principles derived from the National Guidelines on Responsible Business Conduct (NGRBC). 

BRSR requires disclosures across approximately 140 ESG parameters, split into: 

1. Mandatory essential indicators – quantitative and comparable data points (e.g., greenhouse gas emissions, energy usage, workforce diversity, governance practices). 
2. Voluntary leadership indicators – advanced practices reflecting global best standards (e.g., value chain emissions, supplier ESG risks, product life cycle sustainability). 

The framework covers areas such as: 

• Environmental protection and climate responsibility, 
• Employee health, safety, and diversity, 
• Human rights and ethical conduct, 
• Governance transparency and board diversity, 
• Sustainable products, services, and innovation, 
• Tax transparency and anti-corruption policies, 
• Supply chain sustainability and stakeholder engagement. 
• This structure ensures Indian businesses can align with global ESG standards while remaining rooted in national priorities like inclusive growth and responsible public policy engagement. 

Note: Out of the ~140 questions, 98 are essential indicators, which are mandatory for all covered companies. The remaining 42 are leadership indicators, which are voluntary, aimed at companies that wish to go beyond compliance and showcase advanced ESG practices.

Evolution from BRR to BRSR 

SEBI first introduced the Business Responsibility Report (BRR) in 2012 for the top 100 listed companies. BRR was largely qualitative, focusing on broad commitments to CSR and ethical practices.

While this was a step forward at the time, the disclosures were largely qualitative, companies narrated their policies, CSR initiatives, or community programs without providing measurable outcomes. As a result, it was difficult for investors or regulators to compare performance across sectors, assess ESG risks, or track progress over time.

Over the next decade, global capital markets began shifting their priorities. International investors and sustainability rating agencies demanded standardized, data-driven ESG disclosures that could be benchmarked across geographies. This pressure exposed BRR’s limitations: it lacked quantitative metrics, did not align with global frameworks such as GRI, TCFD, or SASB, and completely ignored value chain impacts.

Recognizing this gap, SEBI launched the Business Responsibility and Sustainability Report (BRSR) in 2021. BRSR goes far beyond BRR by introducing 140+ ESG data points, many of which are quantitative and verifiable. Unlike BRR’s 36 broad, narrative-style questions, BRSR requires companies to provide auditable disclosures on emissions, water use, employee diversity, governance structures, tax transparency, and even ESG practices across their value chains.

This evolution reflects a strategic shift in how companies are expected to approach sustainability. Under BRR, CSR was often treated as philanthropy, a set of projects reported outside the core business model. With BRSR, ESG becomes part of the business strategy itself, integrated into financial planning, operational execution, and enterprise risk management.

The leap from 36 qualitative questions in BRR to 140+ structured data points in BRSR also signals the rising demand for internal data management systems, cross-functional coordination, and independent assurance. Companies can no longer rely on CSR teams alone; sustainability reporting now requires inputs from finance, HR, procurement, legal, and operations, backed by verifiable evidence.

Compliance Requirements and Regulatory Landscape 

BRSR’s regulatory design reflects SEBI’s ambition to mainstream ESG practices across India’s corporate ecosystem. Its phased implementation began with voluntary disclosure during FY 2021-22 but, from FY 2022–23, it is mandatory for the top 1,000 listed entities.

Key compliance requirements include: 

1. Comprehensive Reporting 
   Companies must submit detailed annual disclosures covering environmental performance (emissions, energy, waste), social initiatives (diversity, employee welfare, community engagement), and governance practices (board composition, whistleblower policies). 

2. Data Accuracy and Traceability 
   Data must be validated and auditable, supported by utility bills, invoices, and financial statements. This minimizes greenwashing and enhances credibility. 

3. Assurance and Verification 
   While not fully mandatory yet, SEBI encourages third-party assurance for BRSR data. This trend will strengthen in coming years, especially for value chain disclosures. This third-party assurance on the key ESG parameters which are part of the BRSR Core, required to be initiated by Top 150 companies from FY 2023-24. By end of FY-2027-28, all the Top 1000 companies will come reasonable assurance ambit. 

4. Annual Public Filing 
   BRSR is submitted with the annual report and disclosed publicly on the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE) websites, ensuring stakeholders can benchmark companies. 

5. Consequences of Non-Compliance 
   Non-adherence can trigger SEBI penalties, reputational damage, exclusion from ESG indices, and difficulty accessing ESG-linked financing. 

This regulatory landscape emphasizes that BRSR is not merely about box-ticking. It is about integrating ESG practices into mainstream corporate governance and financial strategy.

Best Practices for Effective BRSR Reporting 

Companies that treat BRSR as a compliance burden will miss its strategic potential. To convert reporting into a competitive advantage, organizations should adopt the following practices: 

1. Embed ESG into Corporate Strategy 
   ESG must be treated as integral to business planning. For example, carbon reduction targets should align with operational cost savings, and board diversity should link to innovation outcomes. 

2. Develop Robust Data Systems 
   Digital tools for ESG data collection and reporting (such as sustainability management platforms) reduce manual errors, enable real-time monitoring, and ensure audit-readiness. 

3. Cross-Functional Collaboration 
   ESG data spans multiple functions- environment, HR, procurement, legal, finance. Coordinated workflows avoid siloed reporting and ensure holistic disclosure. 

4. Training and Capacity Building 
   Employees and suppliers must understand ESG principles. Regular training fosters alignment and empowers stakeholders to contribute credible data. 

5. Stakeholder Engagement 
   Reporting should not be an inward exercise. Communicating progress to investors, customers, and communities enhances trust and brand value. 

6. Independent Verification 
   Third-party audits and certifications lend credibility and highlight areas for improvement, strengthening long-term sustainability performance. 

7. Monitor Evolving Frameworks 
   ESG reporting standards are dynamic. Staying ahead of SEBI updates and global best practices ensures sustained compliance and competitiveness.

Detailed BRSR Compliance Checklist for FY 2025–26 

To help organizations operationalize compliance, here is a structured checklist aligned with SEBI guidelines:

1. General Compliance
Before diving into data collection, companies must establish the foundation for BRSR reporting. This involves confirming whether the organization falls within SEBI’s mandated scope and adopting the correct reporting format. 

Confirm Applicability: Ensure the company is among the top 1,000 listed entities by market capitalization. Applicability is strictly tied to SEBI’s listing obligations, and failure to comply exposes firms to penalties and reputational risk. 

Adopt Relevant Format: Select the appropriate BRSR format: 

• BRSR Core (mandatory for large entities), 
• Comprehensive (covering all indicators), or 
• Lite (for smaller or transitioning entities). 
  The chosen format dictates the depth of disclosures. 

Ensure Alignment with NGRBC: The nine National Guidelines on Responsible Business Conduct principles form the backbone of BRSR. Companies must show consistency between their sustainability strategy and NGRBC priorities. 

Annual Filing and Disclosure: BRSR must be filed with SEBI alongside the annual report and made publicly available ahead of the Annual General Meeting (AGM). This ensures transparency for shareholders and stakeholders. 

2. Reporting Scope
BRSR goes beyond broad CSR-style reporting. Companies are expected to disclose across nearly 140 ESG data points, covering environmental, social, and governance dimensions. 

Environmental Metrics: These cover energy efficiency, emissions, and waste management, ensuring companies quantify their environmental footprint rather than describing it qualitatively. 

Social Metrics: Reporting must address employee health and safety, diversity ratios, welfare benefits, and community programs, reflecting how organizations impact people both inside and outside the company. 

Governance Metrics: These include board independence, ethical practices, tax transparency, and anti-corruption mechanisms, factors that reassure investors about accountability and risk management. 

By disclosing under all three pillars, companies provide a comprehensive picture of their ESG performance. 

3. Attribute-Wise Detailed Requirements
For FY 2025–26, disclosures need to go deeper into specific ESG attributes. Each requirement is tied to measurable outcomes and global comparability. 

GHG Emissions: Report Scope 1 (direct) and Scope 2 (indirect from purchased electricity) emissions. Disclose emission factors used, initiatives taken to reduce emissions, and targets for future reduction. This aligns with TCFD and global climate frameworks. 

Water Footprint: Provide source-wise consumption (groundwater, municipal, surface). Where measurement is not feasible, use Central Ground Water Authority guidelines for estimates. Companies must also report efficiency measures to show responsible water use. 

Energy Usage: Report total energy consumption, segregated between renewable and non-renewable sources. Disclose on-site generation, renewable procurement, and conservation initiatives. This links directly to India’s energy transition goals. 

Waste Management: Classify hazardous and non-hazardous waste, disposal methods, recycling rates, and circular economy initiatives. SEBI expects evidence of reduction and reuse efforts rather than just disposal reporting. 

Employee Well-being: Include data on health and accident insurance coverage, workplace safety statistics, maternity/paternity benefits, and occupational health programs. This ensures employee welfare is quantified rather than vaguely stated. 

Diversity and Inclusion: Disclose workforce gender diversity, women in leadership roles, and inclusion programs. These disclosures address both equity and compliance with Indian labor laws. 

Governance Practices: Provide detailed information on board independence and diversity, whistleblower policies, anti-bribery measures, and cybersecurity frameworks. This helps investors assess resilience against governance failures. 

Value Chain Disclosures: From FY 2025–26, reporting on suppliers and customers contributing at least 2% of trade remains voluntary, but companies are encouraged to disclose ESG risks in their value chain. From FY 2026–27, this will be mandatory with assurance requirements. Early adoption will give companies a head start. 

4. Assurance and Verification
One of SEBI’s priorities is ensuring credibility and comparability of data. Companies must prepare for increasing verification demands. 

• Third-Party Assurance: While assurance is mandatory for top 500 listed companies currently, which is expected to extend to all 1000 companies by FY 2026-27. SEBI recommends independent verification on environmental, social and governance data based on BRSR Core Framework. External assurance builds stakeholder confidence and reduces accusations of greenwashing. 

• Record Retention: Maintain all supporting documentation, utility bills, invoices, HR data, audit records, for at least two financial years. This not only prepares organizations for verification but also helps with year-on-year trend analysis. 

• Audit Readiness: Develop systems that allow traceability of data back to source records. This ensures auditors can validate disclosures without discrepancies.

Conclusion

India’s BRSR framework marks a turning point in how corporate sustainability is measured, reported, and evaluated. It moves companies away from broad CSR narratives and into the realm of quantitative, comparable, and auditable ESG disclosures that align with global standards. For listed entities, compliance is only the starting line. The real opportunity lies in embedding ESG into strategy, reducing risks, and positioning for access to global capital markets where credible sustainability reporting is now a prerequisite. 

Yet, for many organizations, meeting BRSR requirements is not straightforward. It demands robust data systems, cross-functional coordination, independent assurance, and a clear understanding of how regulatory expectations are evolving. Missteps can result not only in compliance penalties but also in higher financing costs and reputational risks.
