To improve esg rating india outcomes, a listed Indian company should raise data completeness across all BRSR essential and leadership indicators, obtain BRSR Core reasonable assurance on environmental KPIs, and lift disclosure quality, since SEBI-registered ERPs such as CRISIL, CareEdge and ICRA score reliability and governance, not environment alone.
Where Indian ESG ratings originate
ESG ratings for listed Indian companies are issued by ESG Rating Providers (ERPs) registered with SEBI under the SEBI (Credit Rating Agencies) Regulations 1999 and the SEBI Master Circular for ESG Rating Providers reissued on 11 July 2025. Providers on the public register include CRISIL ESG Ratings and Analytics, CARE ESG Ratings (CareEdge), ICRA ESG Ratings, ESG Risk Assessments and Insights (Acuité) and SES ESG Research, among SEBI-registered ERPs. These ratings draw heavily on a company’s Business Responsibility and Sustainability Report, the statutory disclosure mandatory for the top 1,000 listed entities from FY 2022-23.
The levers that lift a score
Three levers move a rating: data completeness, disclosure quality and assured data. Full population of the roughly 140 BRSR indicators (98 essential and 42 leadership) closes the gaps that suppress scores. BRSR Core reasonable assurance, phased in by market-capitalisation rank from the top 150 in FY 2023-24 to the top 1,000 in FY 2026-27, strengthens the reliability of the environmental KPIs that ratings rely on most. Since the SEBI circular dated 28 March 2025, an entity may obtain either reasonable assurance or a third-party assessment under Industry Standards Forum standards.
- Complete every essential and leadership indicator, not only the mandatory minimum.
- Secure reasonable assurance on the nine BRSR Core ESG attributes.
- Cross-reference GRI, SASB and TCFD disclosures so one dataset serves several frameworks.
Weighting is not always environment-heaviest
Pillar weighting differs by provider and is not always environment-heaviest. The CRISIL ESG Ratings methodology dated May 2026 weights governance highest.
| Pillar | CRISIL weight (May 2026) |
|---|---|
| Governance | 40% |
| Environment | 35% |
| Social | 25% |
A strong governance narrative therefore matters as much as emissions data. Preparing the underlying data file and readiness for independent assurance is advisory work; the assurance and the rating itself are performed by independent accredited third parties and the SEBI-registered ERP respectively. An ESG discovery session can map current gaps before a rating cycle.
