ESG and Sustainable Finance in India: SEBI's BRSR Framework, Green Bond Standards, and Investment Obligations

Environmental, social, and governance (ESG) considerations have moved from the periphery to the center of corporate and investment practice in India over the past five years. The shift has been driven by a combination of regulatory mandate, institutional investor demand, and the integration of sustainability risk into mainstream credit and equity analysis. India's regulatory response to the ESG agenda has been led principally by the Securities and Exchange Board of India, which has built a comprehensive ESG disclosure architecture around the Business Responsibility and Sustainability Report (BRSR) framework and introduced the ESG Rating Providers (ERP) regime, the BRSR Core assurance requirement, and an ESG Scheme category for mutual funds. This blog examines the architecture of India's sustainable finance regulatory framework, evaluates the obligations it imposes on listed companies, asset managers, and investors, and situates the Indian approach within the comparative context of the EU's Corporate Sustainability Reporting Directive, the International Sustainability Standards Board's IFRS S1 and S2 standards, and the Securities and Exchange Commission's climate disclosure rules. This blog contends that India has constructed a credible and increasingly demanding ESG disclosure regime but that the absence of a mandatory Scope 3 emissions reporting requirement reflects an omission that undermines the framework's systemic completeness.

The BRSR Framework: Architecture and Mandatory Application

The Business Responsibility and Sustainability Report is India's principal ESG disclosure instrument for listed companies. SEBI introduced the BRSR in May 2021 as the successor to the Business Responsibility Report (BRR), which had been mandated for the top 1,000 listed companies (by market capitalisation) since 2012. The BRSR made disclosure mandatory for the top 1,000 listed entities from the financial year 2022-23.¹

The BRSR is structured around nine principles derived from the National Guidelines on Responsible Business Conduct (NGRBC) published by the Ministry of Corporate Affairs in 2019. The nine principles cover: businesses conducting and governing themselves with integrity; businesses providing sustainable products and services; businesses respecting and promoting the wellbeing of all employees; businesses respecting the interests of all stakeholders; businesses respecting and promoting human rights; businesses respecting the environment; businesses engaging in responsible policy advocacy; businesses promoting inclusive growth; and businesses engaging responsibly with consumers. For each principle, the BRSR requires essential indicators (mandatory for the top 1,000 companies) and leadership indicators (voluntary, aspirational disclosures for the same population).

The BRSR Core, introduced by SEBI in 2023, represents a significant deepening of the framework. The BRSR Core mandates assurance – either reasonable assurance or limited assurance from a qualified independent assessor – for a subset of Key Performance Indicators (KPIs). The mandatory KPIs subject to assurance in the BRSR Core include: greenhouse gas emissions (Scope 1 and Scope 2); energy consumption and intensity; water consumption and intensity; waste generation; employee wellbeing metrics; and supply chain ESG disclosures for the top 250 listed entities from 2024-25.² The BRSR Core's assurance requirement is the first mandatory third-party sustainability assurance obligation in Indian law and represents a substantive step toward the auditability standards imposed by the EU's Corporate Sustainability Reporting Directive (CSRD).

ESG Rating Providers: The New Regulatory Layer

SEBI's introduction of a regulatory framework for ESG Rating Providers (ERPs) through the Securities Contracts (Regulation) (Stock Exchanges and Clearing Corporations) Regulations framework, and subsequently through a dedicated SEBI circular in July 2023, addresses a market integrity concern common to all ESG rating markets: the potential for conflicts of interest, inconsistent methodologies, and "greenwashing" arising from unregulated rating activity.³

ERPs providing ratings on Indian securities or to Indian-regulated entities are required to register with SEBI and comply with requirements on organisational structure, conflict of interest management, methodology disclosure, analyst competence, and appeals mechanism. The framework is broadly consistent with the approach taken by the European Securities and Markets Authority (ESMA) in its proposed ESG Rating Regulation, published as a proposal in June 2023 and adopted by the EU Council in November 2024, which regulates ESG rating providers accessing EU markets on similar terms.

The ERP regulatory framework addresses a deficiency in the sustainability information chain. The value of mandatory BRSR disclosure depends on the quality of the analytical framework that converts raw disclosure data into investable ESG assessments. A regulated ERP regime – with consistent methodology disclosure, conflict of interest firewalls, and accountability to a supervising regulator – creates stronger incentives for analytical rigour than the unregulated market structure it replaces.

Green Bond Standards: SEBI's Green Debt Securities Framework

SEBI's Green Debt Securities framework, operationalised through an amendment to the SEBI (Issue and Listing of Non-Convertible Securities) Regulations, 2021 and the associated circular on green bonds and sustainable finance debt instruments, provides a regulatory architecture for the issuance and listing of green bonds, blue bonds, social bonds, and sustainability-linked bonds on Indian exchanges.⁴

The framework requires issuers of green and sustainable bonds to appoint an independent third-party reviewer to assess the alignment of the proposed use of proceeds with the applicable bond taxonomy and to issue a second-party opinion prior to issuance. Post-issuance, the issuer must provide annual reports on the allocation of bond proceeds and the environmental or social impact achieved. The framework draws on the International Capital Market Association's (ICMA) Green Bond Principles and Social Bond Principles as the international reference standards, with SEBI's National Green Bond Framework providing the Indian-specific taxonomy for eligible green projects.

India issued its inaugural Sovereign Green Bond in January 2023: Rs. 8,000 crore in two tranches (5-year and 10-year) at yields that attracted significant domestic and foreign institutional investment. The sovereign issuance was structured in alignment with the National Green Bond Framework, with proceeds directed toward renewable energy, clean transportation, sustainable water management, and pollution control. The sovereign green bond programme signals India's commitment to mobilising bond market capital for its net-zero transition, with a stated objective of increasing non-fossil fuel energy capacity to five hundred gigawatts by 2030.

ESG Mutual Funds and the SEBI Circular on ESG Schemes

SEBI has created a dedicated regulatory category for ESG mutual funds under the SEBI (Mutual Funds) Regulations, 1996, requiring mutual funds that use ESG or sustainability-related labels in their product names to demonstrate substantive compliance with prescribed ESG investment strategies.⁵ The ESG investing strategies recognised by SEBI include: exclusion (excluding sectors or companies from the investable universe on ESG grounds); integration (integrating ESG factors into financial analysis); best-in-class or positive screening; impact investing; and sustainable objectives.

SEBI's requirement that ESG-labelled mutual funds invest at least sixty-five per cent of their assets in companies with BRSR disclosures operationalises the connection between the disclosure framework and the investment product market. Fund managers whose products carry ESG labels must now demonstrate that their investment process substantively applies the stated ESG methodology, and are subject to SEBI's oversight in this regard. The overlay of SEBI's anti-greenwashing framework on ESG mutual funds mirrors the European Commission's Sustainable Finance Disclosure Regulation (SFDR) framework and its Articles 8 and 9 classification for ESG-oriented investment products.

Global Comparisons: CSRD, ISSB Standards, and SEC Climate Disclosure

The EU's Corporate Sustainability Reporting Directive (CSRD), which entered into force in January 2023 and is being implemented in phases from 2024, requires large companies and listed SMEs to disclose sustainability information in accordance with European Sustainability Reporting Standards (ESRS) developed by the European Financial Reporting Advisory Group (EFRAG).⁶ The CSRD imposes double materiality: companies must disclose both the impact of sustainability matters on their financial position (financial materiality) and the impact of their activities on people and the environment (impact materiality). The double materiality concept goes beyond the BRSR framework's currently single-materiality approach and represents a standard that India may need to require of large listed entities as the BRSR regime matures.

The International Sustainability Standards Board (ISSB), established at COP26, published its inaugural standards – IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures) – in June 2023. IFRS S2 is substantially aligned with the Task Force on Climate-related Financial Disclosures (TCFD) framework and requires disclosure of Scope 1, Scope 2, and Scope 3 greenhouse gas emissions. India has not yet mandated ISSB adoption, but SEBI has indicated its intention to align the BRSR framework progressively with ISSB standards.⁷

Conclusion

India's BRSR framework, BRSR Core assurance requirement, ESG Rating Provider regime, and green bond standards collectively constitute a materially more sophisticated ESG regulatory architecture than existed five years ago. This blog has argued that the BRSR Core's introduction of mandatory third-party assurance is the most significant structural advance, that the ERP framework addresses a genuine market integrity gap, and that the absence of Scope 3 emissions reporting – required under IFRS S2 and the EU CSRD – is the most significant omission in the current BRSR architecture. Institutional investors and corporate issuers operating in the Indian market should treat ESG disclosure obligations as a first-order compliance matter, benchmark their current reporting against the BRSR Core KPIs, and plan for progressive alignment with ISSB standards as SEBI's stated convergence trajectory becomes regulatory mandate.
