ESG Reporting Frameworks — BRSR, GRI, TCFD, SASB | Nainit Savla & Associates

ESG Reporting Frameworks

Q: How does BRSR relate to GRI — can a company use both?

BRSR and GRI are compatible with significant content overlap. Many large Indian companies produce a single sustainability report structured around BRSR with a GRI Content Index — one document meeting both SEBI compliance and international investor ESG expectations efficiently.

Q: What is materiality in ESG reporting and why does it matter?

Materiality identifies which ESG topics a company should prioritise based on business significance and stakeholder concerns. GRI uses double materiality (impact + financial); SASB and ISSB use single financial materiality. A proper materiality assessment is the foundation of credible, focused ESG reporting.

Q: What is the ISSB and how will it affect Indian companies?

ISSB issued IFRS S1 and S2 in 2023 as the emerging global baseline for sustainability-related financial disclosures. Multiple jurisdictions have announced adoption. SEBI is monitoring for potential incorporation into India's framework. Indian companies with international exposure should begin familiarising themselves with ISSB requirements.

Q: What is double materiality and how is it assessed?

Double materiality assesses impact materiality (company's effect on environment/society) and financial materiality (ESG effects on company finances) simultaneously — required by GRI 2021 and European CSRD. Assessment involves stakeholder engagement, peer benchmarking, and risk analysis.

Q: How frequently should ESG reports be published?

BRSR is filed annually with the Annual Report. GRI standalone reports are typically published within 6 months of year-end. CDP responses are annual. Investors increasingly expect in-year progress updates on key climate and diversity commitments between annual reports.

ESG reporting frameworks are structured systems that define what companies should disclose about their sustainability performance — which topics to cover, what metrics to report, and how to present disclosures for stakeholder use. With multiple frameworks operating in parallel globally, and India's mandatory BRSR framework sitting alongside voluntary global standards, companies face real complexity in choosing the right framework, meeting multiple requirements efficiently, and presenting their sustainability story in a format that satisfies investors, regulators, customers, and lenders simultaneously. We provide practical advisory on framework selection, gap analysis, and structured disclosure preparation.

SEBI BRSR

Advisory on India's mandatory Business Responsibility and Sustainability Report (BRSR) framework — the nine-principle National Guidelines on Responsible Business Conduct structure, BRSR Core KPIs, and the expanding assurance requirements for listed companies.

GRI Standards

GRI (Global Reporting Initiative) Standards advisory — the world's most widely adopted sustainability reporting framework, covering Universal Standards (GRI 1, 2, 3) and Topic Standards across economic, environmental, and social disclosures.

TCFD Framework

Task Force on Climate-related Financial Disclosures (TCFD) advisory — structured disclosure of climate-related risks and opportunities across governance, strategy, risk management, and metrics and targets for climate-sensitive sectors.

SASB Standards

Sustainability Accounting Standards Board (SASB) advisory — industry-specific sustainability disclosure standards that identify the ESG topics most financially material to each industry for investor-focused reporting.

CDP Disclosure

Carbon Disclosure Project (CDP) response preparation — climate change, water security, and forests questionnaires submitted annually by companies in response to institutional investor or supply chain requests.

ISSB / IFRS Sustainability

Advisory on the International Sustainability Standards Board (ISSB) standards — IFRS S1 (general sustainability disclosures) and IFRS S2 (climate-related disclosures) — the emerging global baseline for sustainability-related financial disclosures.

Which Framework Is Right for Your Company?

Framework selection depends on three factors: regulatory obligation, stakeholder expectations, and company capacity. Listed Indian companies must file BRSR as their primary regulatory obligation. Companies with significant international investor bases typically also report under GRI — which is the most globally recognised framework and is compatible with BRSR disclosure requirements. Climate-sensitive industries (energy, finance, infrastructure, real estate) are expected to align with TCFD by their investors and lenders. Companies responding to institutional investor ESG questionnaires or CDP supply chain requests need CDP-ready disclosures.

Importantly, these frameworks are not mutually exclusive — GRI and BRSR have significant content overlap, and TCFD disclosures can be integrated into a GRI report. We help companies design an integrated reporting approach that meets multiple framework requirements with a single, efficient disclosure process.

Key ESG Frameworks — Quick Reference

BRSR — India mandatory (SEBI) for top 1,000 listed companies; BRSR Core with assurance for top 150 expanding annually
GRI Standards — globally dominant voluntary framework; most widely adopted by Indian multinationals
TCFD — climate-specific framework; increasingly required by financial institutions and investors
SASB — industry-specific financially material ESG metrics; investor-focused
CDP — annual disclosure questionnaire; climate, water, forests; demanded by institutional investors and large corporate buyers
ISSB (IFRS S1, S2) — emerging global baseline; expected to become mandatory in many jurisdictions; aligned with TCFD
UN SDGs — mapping of company activities to the 17 Sustainable Development Goals; commonly used as a narrative overlay
ISO 26000 — guidance standard (not certifiable) on social responsibility; used as a reference for stakeholder engagement

Frequently Asked Questions

How does BRSR relate to GRI — can a company use both?

BRSR and GRI are compatible frameworks with significant content overlap — both require disclosure of environmental metrics (energy, emissions, water, waste), social metrics (employment, health and safety, training, diversity), and governance practices. Many large Indian companies produce a single sustainability report that is structured around BRSR (for SEBI compliance) while also providing a GRI Content Index showing where each GRI disclosure is addressed in the report. This integrated approach — one document, two framework content indexes — is efficient and becoming increasingly common among the top Indian listed companies that have both SEBI compliance obligations and international investor ESG expectations.

What is materiality in ESG reporting and why does it matter?

Materiality in ESG reporting determines which ESG topics a company should prioritise and disclose — based on their significance to the company's business and the concerns of its stakeholders. GRI uses a "double materiality" concept — topics are material if they have significant impact on the economy, environment, or society (impact materiality) or if they affect the company's financial performance or position (financial materiality). SASB and ISSB use single financial materiality — disclosing only what is material to investors. BRSR requires companies to address all prescribed topics regardless of materiality but also asks companies to identify their principal risks and opportunities. A proper materiality assessment is the foundation of a credible, focused ESG report — rather than a boilerplate disclosure that covers everything superficially.

What is the ISSB and how will it affect Indian companies?

The ISSB (International Sustainability Standards Board) was established by the IFRS Foundation in 2021 — the same body that oversees IFRS accounting standards. ISSB issued IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures) in 2023. These standards are designed to become the global baseline for sustainability-related financial disclosures — analogous to what IFRS is for financial accounting. Several jurisdictions (UK, Australia, Japan, Singapore) have already announced adoption timelines. SEBI is monitoring ISSB developments for potential incorporation into India's sustainability reporting framework. Indian companies with international listings, cross-border financing, or global supply chains should begin familiarising themselves with ISSB requirements to prepare for their likely eventual adoption in India.

What is double materiality and how is it assessed?

Double materiality — central to GRI's 2021 revision and the European CSRD framework — assesses materiality from two perspectives simultaneously: (a) impact materiality: how significantly does the company's business impact the environment, society, and economy — positive and negative, actual and potential, short and long-term? (b) financial materiality: how significantly do ESG factors affect the company's financial condition, performance, cash flows, and access to capital? Topics that are material from either perspective must be disclosed. The double materiality assessment involves stakeholder engagement, peer benchmarking, impact analysis, and risk and opportunity evaluation — typically conducted annually by the sustainability or corporate affairs team with input from senior management.

How frequently should ESG reports be published?

BRSR is filed annually as part of the listed company's Annual Report — aligned with the financial year (April to March in India). GRI-aligned standalone sustainability reports are also typically published annually, usually within 6 months of the financial year-end. CDP responses are submitted once annually in response to the CDP investor or supply chain questionnaire cycle (typically July or September each year). Some companies publish interim ESG updates (half-year or quarterly) for specific investor audiences. The minimum expectation for any company with public ESG commitments is an annual disclosure — and increasingly, investors expect in-year progress updates on key climate and diversity commitments between annual reports.
