ESG and Sustainable Mutual Funds in India: Institutional Adoption Roadmap

ESG-themed mutual fund AUM in India has grown from roughly ₹2,747 crore in early 2020 to an estimated ₹9,700–10,800 crore by 2024–2025 — a meaningful multiple, but still a small fraction of the industry’s roughly ₹82 lakh crore total assets. The more consequential development is not the AUM figure itself but the regulatory infrastructure SEBI has built around it: mandatory Business Responsibility and Sustainability Reporting (BRSR) for large listed companies, a BRSR Core assurance requirement now embedded directly into ESG fund eligibility rules, and a 2025 reform permitting AMCs to launch multiple ESG schemes with clearly named, differentiated strategies. For institutional allocators and AMC leadership, the practical roadmap question is how quickly India’s ESG disclosure infrastructure matures enough to support genuinely differentiated, defensible sustainable investment products at scale.

Introduction

ESG investing in India has followed a different path than in Europe or the United States, where retail demand often preceded regulatory infrastructure. In India, SEBI’s disclosure framework — BRSR, then BRSR Core — has been built largely ahead of retail demand, positioning the regulator as an active architect of ESG data quality rather than a reactive enforcer responding to an already-mature market.

Industry Background

SEBI classifies ESG funds as thematic equity mutual funds, a categorisation that itself signals a conservative regulatory stance: ESG is treated as one investment theme among several, not a separate asset class deserving distinct regulatory treatment. Since 2023, the framework has required that all ESG schemes clearly disclose their specific ESG strategy in the scheme’s name and structure, explicitly aiming to reduce the risk of misleading sustainability claims that has drawn criticism of ESG investing in more mature markets.

Current Market Landscape

As of the current framework, ESG schemes must invest at least 80% of assets in line with their declared ESG strategy and at least 65% of AUM in companies providing assured BRSR Core disclosures, with full compliance required by September 30, 2025. Following this tightening, SEBI simultaneously loosened the product-design constraint that had previously limited each AMC to a single ESG scheme, allowing multiple ESG schemes with distinct named strategies — exclusionary, best-in-class, integration, and others — provided each meets the underlying allocation and disclosure thresholds.

Latest Industry Statistics

Recent performance data suggests ESG funds in India have moved past their early “ethical but lower-return” reputation: several leading ESG funds reported five-year CAGRs in the 18–22% range as of a 2025 snapshot, broadly competitive with diversified equity peers, while a separate analysis of thematic ESG funds found a three-year average return of approximately 16.5% with a median of 14.67%. SEBI’s BRSR framework currently mandates comprehensive sustainability disclosure for the top 1,000 listed companies, with BRSR Core and value-chain reporting coverage thresholds continuing to expand toward FY27, a trajectory expected to improve underlying ESG data quality and further reduce greenwashing risk over the medium term.

Regulatory & Policy Updates

SEBI’s regulatory sequence has been deliberate: first, mandate comprehensive BRSR disclosure across large listed companies; second, require ESG schemes to invest a defined majority of assets in companies meeting BRSR Core assurance standards; third, once that data foundation existed, relax the one-scheme-per-AMC constraint to allow product differentiation. This build-then-open sequencing is distinct from SEBI’s approach in some other domains (such as its more exploratory, pilot-based approach to tokenization), reflecting a regulator that treats sustainability-linked financial claims as requiring a verified data foundation before product proliferation is permitted.

Key Industry Challenges

The most significant institutional adoption barrier remains data quality and comparability: even with BRSR Core assurance requirements, ESG scoring methodologies vary meaningfully across rating agencies and AMCs, meaning portfolio composition can differ substantially between funds claiming similar ESG strategies. A second challenge is scale economics — ESG remains a small enough category that many schemes lack the AUM to justify dedicated research and stewardship infrastructure proportionate to genuine ESG integration, as opposed to a lighter-touch exclusionary screen. A third challenge is investor education: many retail investors continue to associate ESG investing with lower returns despite recent performance data suggesting otherwise, a perception gap that constrains demand-side growth even as supply-side product options expand.

Strategic Analysis

The multiplicity reform creates a genuine strategic inflection point for AMCs with credible ESG research capability: rather than a single, generically-labelled ESG scheme competing for a small pool of assets, AMCs can now build a genuine ESG product suite — differentiated by strategy type and target investor — that better matches institutional allocators’ increasingly specific ESG mandates (some institutional investors want strict exclusionary screens, others want best-in-class integration approaches). AMCs without differentiated ESG data infrastructure, however, risk launching multiple schemes that are ESG in name only, precisely the greenwashing risk SEBI’s disclosure tightening is designed to prevent.

Technology Trends

ESG data infrastructure — automated BRSR Core disclosure verification, real-time portfolio-level ESG scoring, and audit-ready documentation of how each scheme’s declared strategy translates into actual holdings — is becoming a genuine technology differentiator for AMCs competing in this space, not a back-office compliance afterthought. This mirrors the broader pattern across SEBI’s recent regulatory wave, where documented, auditable evidence increasingly matters as much as the underlying investment decision itself.

Business Implications

For CXOs evaluating ESG product strategy, the practical decision is whether to build genuine differentiated ESG research capability to support multiple schemes under the new multiplicity rules, or to maintain a single, well-resourced ESG offering rather than diluting research depth across several thinly-differentiated products. For institutional allocators and family offices increasingly asked to demonstrate ESG integration in their own reporting, India’s improving BRSR Core data foundation offers a more defensible basis for ESG allocation decisions than was available even two years ago.

Case Studies

SEBI’s BRSR Core integration into ESG fund eligibility. By requiring ESG schemes to invest at least 65% of AUM in companies providing assured BRSR Core disclosures, SEBI directly linked fund-level ESG claims to company-level, independently assured sustainability data — a structural design choice that distinguishes India’s ESG fund framework from jurisdictions where fund-level ESG claims can rely more heavily on third-party ratings without equivalent underlying company disclosure assurance requirements.

The ESG scheme multiplicity reform. SEBI’s move to permit multiple named ESG strategies per AMC, following the earlier one-scheme restriction, illustrates a broader regulatory pattern of expanding product flexibility only after the corresponding disclosure infrastructure (BRSR Core assurance) was in place. Early evidence of this approach’s effect on genuine strategy differentiation, rather than simple product proliferation, will be an important signal for how successfully the reform achieves its intended purpose over the next reporting cycle.

Best Practices

AMCs should treat BRSR Core data quality as core research infrastructure rather than a compliance checkbox, given that fund-level ESG credibility now depends directly on the assurance quality of underlying portfolio company disclosures. Before launching additional ESG schemes under the multiplicity reform, AMCs should validate that each proposed strategy has genuinely distinct research and portfolio construction logic, not just a different name applied to a similar underlying holdings set.

Executive Recommendations

Boards overseeing ESG product lines should require explicit evidence that each ESG scheme’s declared strategy (exclusionary, best-in-class, integration) produces a portfolio genuinely differentiated from the AMC’s other ESG offerings, both to satisfy SEBI’s disclosure intent and to protect against reputational greenwashing risk. Institutional investors and family offices allocating to ESG mutual funds should request specific BRSR Core assurance evidence for underlying portfolio holdings rather than relying solely on the fund’s ESG label or marketing description.

Future Outlook

BRSR Core and value-chain reporting coverage is set to expand through FY27, which should meaningfully improve the underlying data foundation for ESG fund construction and disclosure over the next two to three years. Institutional adoption is likely to grow steadily as data quality improves, though ESG is likely to remain a moderate-sized thematic category within the broader industry rather than approaching the scale seen in more mature international ESG markets in the near term.

Conclusion

India’s ESG mutual fund category remains small in absolute AUM terms, but SEBI’s disclosure-first regulatory sequencing has built a more defensible data foundation than exists in many more mature ESG markets. AMCs and institutional allocators that engage seriously with BRSR Core data quality, rather than treating ESG labelling as a marketing exercise, are best positioned as the category scales.

Frequently Asked Questions

1. How large is the ESG mutual fund category in India? ESG-themed mutual fund AUM grew from roughly ₹2,747 crore in early 2020 to an estimated ₹9,700–10,800 crore by 2024–2025, still a small fraction of the industry’s total AUM.

2. What is SEBI’s BRSR Core requirement for ESG funds? ESG schemes must invest at least 65% of AUM in companies providing assured Business Responsibility and Sustainability Reporting (BRSR) Core disclosures, alongside investing at least 80% of assets per their declared ESG strategy.

3. Can an AMC launch more than one ESG fund in India? Yes — SEBI has removed the earlier restriction limiting AMCs to a single ESG scheme, now permitting multiple ESG schemes with distinct, clearly named strategies.

4. Do ESG funds in India underperform conventional equity funds? Recent data suggests otherwise — several leading ESG funds reported five-year CAGRs in the 18–22% range, broadly competitive with diversified equity peers.

5. What are the main ESG fund strategy types permitted in India? Common strategies include exclusionary, best-in-class, and integration approaches, each of which must be explicitly named in the scheme’s title under SEBI’s disclosure rules.

6. What is BRSR Core, and why does it matter for ESG funds? BRSR Core is an assurance-backed subset of India’s Business Responsibility and Sustainability Reporting framework, intended to provide more reliable, verifiable ESG data than voluntary disclosures alone.

7. Is greenwashing a risk in Indian ESG mutual funds? SEBI’s disclosure and naming requirements are specifically designed to reduce this risk, though variation in ESG scoring methodology across funds and rating agencies remains a genuine challenge for comparability.

8. How is institutional demand for ESG funds evolving in India? Institutional allocators increasingly request specific evidence of ESG strategy differentiation and underlying BRSR Core assurance, reflecting a shift from simple ESG-label-based allocation toward more scrutinised, data-backed decisions.
