ESG Reporting Frameworks
Navigating BRSR, GRI, ISSB and Global Standards for Indian Companies
Regulatory and stakeholder mapping, framework gap analysis, unified reporting architecture, pilot reporting, multi-framework production and assurance coordination — one verified dataset, every required output format.
Overview
What Are ESG Reporting Frameworks and Why Do They Matter for Indian Companies?
ESG reporting has become one of the most complex areas of corporate compliance — not because the underlying concepts are complicated, but because the sheer number of frameworks, standards, and guidelines can overwhelm companies trying to determine what they need to report, to whom, and in what format. Between the BRSR, GRI, ISSB, TCFD, SASB, and the UN SDGs, companies face a reporting landscape that looks more like an alphabet soup than a coherent system. The good news is that this landscape is consolidating. The bad news is that consolidation is not yet complete, and companies operating in multiple jurisdictions or serving diverse stakeholder groups still need to navigate multiple frameworks simultaneously.
N D Savla & Associates helps Indian companies make sense of this complexity. Our ESG reporting framework advisory covers the full spectrum of applicable standards — from SEBI's mandatory BRSR format to globally recognised frameworks like GRI Standards, ISSB Standards, and TCFD recommendations. We help companies identify which frameworks apply to them, map the overlaps and gaps between frameworks, and build reporting systems that produce consistent data formatted for multiple audiences. Our framework advisory integrates with our ESG accounting and ESG audit services to provide a complete, end-to-end ESG reporting solution, grounded in our comprehensive ESG services practice.
Our approach is practical, not academic. We do not deliver lengthy comparative analyses of framework features that leave clients more confused than when they started. We identify the specific reporting obligations that apply to each client, design a reporting architecture that satisfies all of them, and implement systems that produce the required disclosures efficiently and accurately.
For Indian companies, ESG reporting frameworks matter because they determine what gets reported, how it gets measured, and whether it gets audited. The Securities and Exchange Board of India has mandated the BRSR as the national reporting framework for listed companies. Simultaneously, global investors expect disclosures aligned with international frameworks like GRI and ISSB. Companies that export to the European Union face additional reporting requirements under the CSRD. And companies seeking green finance must provide disclosures aligned with the Climate Bonds Standard or the Green Bond Principles. Understanding which frameworks apply — and how they relate to each other — is essential for efficient and compliant ESG reporting.
The reporting framework landscape is currently in a period of consolidation. The International Sustainability Standards Board, established under the IFRS Foundation in 2021, is creating a global baseline of sustainability disclosure standards that are designed to work alongside local requirements like the BRSR. The GRI has agreed to a collaboration with the ISSB to ensure compatibility between its impact-focused framework and the ISSB's investor-focused standards. Over time, this convergence should simplify the reporting burden for companies — but in the interim, navigating multiple frameworks remains a practical challenge.
The Frameworks
Which ESG Reporting Frameworks Apply to Indian Companies?
BRSR — The Mandatory Indian Framework
The Business Responsibility and Sustainability Report is the only legally mandated ESG reporting framework in India. Issued by SEBI through circular SEBI/HO/CFD/CMD-2/P/CIR/2021/562, the BRSR applies to the top 1000 listed companies by market capitalisation and must be included in the annual report filed with the stock exchanges. The BRSR is structured around nine principles derived from the National Guidelines on Responsible Business Conduct, with each principle covering specific essential and leadership indicator disclosures. The BRSR Core — a subset of the most material and comparable parameters — is subject to mandatory reasonable assurance for the top 150 companies.
GRI Standards — The Global Impact-Focused Framework
The Global Reporting Initiative Standards are the most widely used ESG reporting framework globally. GRI takes a double materiality approach — requiring companies to report on topics that have significant environmental, social, or economic impact, regardless of whether those topics also affect the company's financial performance. Indian companies with global stakeholders frequently report under GRI Standards alongside their mandatory BRSR disclosures. Our firm assists companies in preparing GRI-compliant reports that are consistent with their BRSR data, leveraging our ESG assurance and certification practice for independent verification.
ISSB Standards — The Global Investor-Focused Baseline
The International Sustainability Standards Board issued its first two standards — IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures) — in June 2023. These standards are designed to provide investors with decision-useful sustainability information. SEBI has indicated its intention to incorporate ISSB concepts into the Indian framework. Companies that adopt ISSB Standards early will be better positioned for future regulatory alignment.
TCFD Recommendations — Climate-Specific Disclosures
The Task Force on Climate-related Financial Disclosures recommendations have become the de facto standard for climate-specific reporting. TCFD focuses on four pillars — governance, strategy, risk management, and metrics and targets — related to climate change. Many of the TCFD recommendations have been incorporated into ISSB's IFRS S2 standard and into SEBI's BRSR climate disclosures. Companies in climate-exposed sectors — energy, mining, agriculture, real estate — should align their reporting with TCFD.
SASB Standards — Industry-Specific Metrics
The Sustainability Accounting Standards Board standards provide industry-specific ESG metrics for 77 industries across 11 sectors. SASB standards focus on financial materiality — identifying the ESG topics most likely to affect financial performance in each industry. The ISSB has incorporated SASB standards into its framework as industry-specific guidance, making them relevant for companies adopting ISSB standards.
At a Glance
ESG Reporting Frameworks Compared
The table below summarises how the five principal frameworks differ in scope, materiality approach, and applicability to Indian companies.
| Framework | Scope | Materiality Approach | Indian Applicability |
|---|---|---|---|
| BRSR | Comprehensive ESG | National guidelines-based | Mandatory for top 1000 listed companies |
| GRI Standards | Comprehensive ESG | Double materiality | Voluntary — widely used by multinationals |
| ISSB Standards | Sustainability-related financial | Financial materiality | Expected future alignment with BRSR |
| TCFD | Climate-specific | Financial materiality | Incorporated in BRSR and ISSB |
| SASB | Industry-specific ESG | Financial materiality | Industry guidance under ISSB |
How It Evolved
How Has the ESG Reporting Framework Landscape Evolved?
The Voluntary Era (2000–2015)
ESG reporting began as a voluntary initiative led by socially responsible companies. The GRI, established in 1997, published its first Sustainability Reporting Guidelines in 2000. The UN Global Compact, launched in 2000, provided a set of principles for responsible business. In India, a small number of large companies — Tata Group, Infosys, Mahindra — published voluntary sustainability reports. There was no standardisation, no regulatory requirement, and limited comparability between reports.
The Regulatory Emergence (2015–2021)
The Paris Agreement in 2015 catalysed regulatory interest in climate-related disclosures. The TCFD was established in 2015 and published its recommendations in 2017. SEBI introduced the Business Responsibility Report in 2012 for the top 100 listed companies. The European Union adopted its Non-Financial Reporting Directive in 2014. India's Companies Act, 2013, introduced mandatory CSR spending under Section 135. These developments signalled a shift from voluntary to regulated ESG disclosure.
The Convergence Era (2021 Onwards)
The establishment of the ISSB in 2021 under the IFRS Foundation marked the beginning of framework convergence. The ISSB consolidated the CDSB and VRF (which had absorbed SASB) into a unified standard-setting body. SEBI replaced the BRR with the more rigorous BRSR in 2021. The EU adopted the Corporate Sustainability Reporting Directive in 2022. The trajectory is towards a global baseline of sustainability disclosure — ISSB Standards — supplemented by jurisdiction-specific requirements such as BRSR. Our firm helps companies prepare for this convergence through our comprehensive regulatory landscape advisory.
The Assurance and Integration Era (2024 Onwards)
The current phase is characterised by two trends: mandatory assurance of ESG disclosures and integration of sustainability information with financial reporting. SEBI's assurance mandate, the EU's CSRD assurance requirements, and the ISSB's design for integration with IFRS financial reporting all point towards a future where ESG information is produced, audited, and communicated with the same rigour as financial information. Companies that begin building integrated reporting capabilities now will have a significant advantage.

How Do Reporting Framework Requirements Differ Across Industries?
Manufacturing
Manufacturers face the most demanding environmental disclosure requirements across all frameworks — energy intensity ratios, Scope 1 and 2 emissions by facility, water stress area assessments, hazardous waste management, and air quality metrics. SASB provides industry-specific guidance for manufacturing sub-sectors that supplements the general framework requirements. The BRSR requires manufacturers to disclose environmental management system certifications, regulatory compliance history, and remediation activities.
Financial Services
Banks and financial institutions face unique reporting challenges related to financed emissions and portfolio-level ESG metrics. The TCFD framework is particularly relevant — requiring disclosures on climate-related risks and opportunities across lending and investment portfolios. The RBI has issued guidance on climate risk disclosures for banks. Our firm assists financial institutions in navigating these requirements through our integrated ESG services practice and corporate governance advisory.
Technology
Technology companies have relatively lighter environmental disclosure requirements but face significant social and governance expectations — data privacy and security, AI ethics, workforce diversity, digital inclusion, and responsible supply chain management for hardware. GRI Standards provide comprehensive social disclosure guidance. The ISSB framework captures technology-specific financial materiality considerations around cybersecurity and data governance.
Real Estate
Real estate companies must report on green building performance, construction materials sourcing, community impact assessments, and project-level environmental data. GRESB — a sector-specific ESG benchmark for real estate — provides additional reporting guidance. The BRSR requires real estate companies to disclose energy efficiency measures, water conservation practices, and environmental clearance compliance.
