ESG Assurance: 9 Attributes Mandated for Indian Boards

In 2023, the Securities and Exchange Board of India (SEBI) introduced a new mandate requiring disclosures and assurance for the value chain of listed entities as per the Business Responsibility and Sustainability Reporting (BRSR) Core. The regulatory expansion shifts corporate accountability beyond direct operations to encompass intricate supplier networks. Companies in India must now scrutinize their entire supply chain, demanding auditable ESG data from external stakeholders, a level of oversight uncommon in global mandatory reporting frameworks.

Companies have increasingly reported on ESG metrics, but the SEBI BRSR Core mandate now demands auditable 'reasonable assurance' and deep value chain scrutiny. Many corporate governance structures are not yet equipped to provide this. The new requirement elevates ESG reporting from a qualitative exercise to a quantitative, verifiable standard, creating tension between existing capabilities and stringent new regulatory expectations.

Indian listed entities face a multi-year, phased transformation of their ESG data management and board oversight. The multi-year, phased transformation will likely separate those with genuine sustainability integration from those with only performative efforts. The mandate compels a re-evaluation of ESG assurance and risk management for corporate boards by 2026, forcing a shift towards deeply embedded, auditable frameworks rather than mere compliance.

The New Mandate: From Voluntary to Verifiable

The SEBI BRSR Core mandate fundamentally redefines corporate ESG reporting in India. It shifts focus from voluntary disclosures to mandatory, auditable data, specifically requiring reasonable assurance on 9 key ESG attributes, according to Glocert International. The SEBI BRSR Core mandate departs from earlier, less rigorous standards, compelling robust internal controls and data collection. SEBI's phased approach requires the top 1000 listed entities to obtain this assurance progressively, as stated by Uniqus. Reasonable assurance demands independent verification, extending beyond data aggregation to the reliability of underlying systems, especially for the value chain. By narrowing the focus to 9 core attributes, SEBI aims for concentrated effort on impactful, auditable areas, driving tangible governance changes and integrating ESG into core risk management.

The BRSR Core's demand for 'reasonable assurance' on 9 key ESG attributes, particularly across the value chain, signifies a fundamental shift from voluntary, qualitative reporting to mandatory, auditable data collection. The BRSR Core's demand for 'reasonable assurance' exceeds typical global expectations, compelling significant investment in ESG data infrastructure, expertise, and internal controls. Companies must develop systems to gather auditable data from direct operations and their entire supply chain, a complex undertaking requiring new technologies and collaboration. While leading global companies like American Tower have proactively embedded ESG into executive compensation and board-level oversight, the BRSR Core will compel all top Indian listed entities to rapidly develop similar, auditable governance structures, regardless of their current maturity. Unprepared firms face substantial compliance hurdles, potential reputational damage, and increased operational costs as they scramble to build robust data and assurance frameworks by the 2026 deadline. By focusing on a subset of 9 critical ESG attributes, SEBI strategically targets the most impactful and auditable areas. The focus on a subset of 9 critical ESG attributes ensures a focused push towards fundamental governance change, creating a competitive disadvantage for those who delay internalizing these stringent requirements. Companies embracing this targeted approach early can optimize resources and position themselves as leaders in sustainable finance, attracting ESG-conscious capital.
