BRSR vs CSRD: Key Differences Indian Companies Must Understand in 2026

Indian companies operating globally or supplying to European markets face a dual sustainability reporting challenge: SEBI's BRSR framework domestically and the EU's Corporate Sustainability Reporting Directive (CSRD) internationally. While both frameworks share the goal of standardising ESG disclosure, they differ significantly in scope, methodology, assurance requirements, and enforcement mechanisms. Understanding these differences is critical for compliance teams, CFOs, and sustainability officers planning their reporting strategy.

Scope and Applicability

BRSR applies to the top 1,000 listed companies on Indian stock exchanges by market capitalisation. It is mandated by SEBI and applies exclusively within the Indian regulatory jurisdiction. CSRD, by contrast, has a far broader reach. It applies to all large EU companies, all EU-listed companies (including listed SMEs), and critically, non-EU companies that generate over EUR 150 million in net turnover in the EU. This means Indian companies with significant EU revenue, subsidiaries in the EU, or those in EU supply chains may need to comply with CSRD reporting standards from FY 2028 onwards.

Reporting Standards and Frameworks

BRSR is built on India's National Guidelines on Responsible Business Conduct (NGRBC) and structured around nine principles covering ethics, sustainability, employee welfare, and stakeholder engagement. The reporting format is prescribed by SEBI with specific templates. CSRD uses the European Sustainability Reporting Standards (ESRS), developed by EFRAG, which are significantly more granular and detailed. ESRS requires a double materiality assessment — evaluating both how sustainability issues affect the company (financial materiality) and how the company affects society and the environment (impact materiality). BRSR does not formally require double materiality, though it does address both dimensions implicitly.

Assurance Requirements

Under BRSR Core, the top 250 Indian companies must obtain reasonable assurance on 42 specific KPIs. The scope of assurance is targeted and phased. CSRD requires limited assurance initially, transitioning to reasonable assurance over time, covering the full breadth of ESRS disclosures. The assurance scope under CSRD is substantially broader, encompassing environmental, social, governance, and value chain disclosures. For Indian companies subject to both, coordinating assurance processes to avoid duplication and optimise cost is a significant planning consideration.

Value Chain and Scope 3 Disclosure

Both frameworks require value chain disclosure, but the depth differs. BRSR asks for basic information on supply chain ESG practices and includes a section on top-of-value-chain disclosures. CSRD and ESRS go much further, requiring detailed Scope 3 emissions accounting, supplier-level ESG data, and transition plan disclosures aligned with the Paris Agreement. Indian textile exporters, auto component manufacturers, IT services firms, and pharmaceutical companies with EU clients should particularly note these enhanced value chain requirements.

How to Manage Dual Compliance Efficiently

The most effective approach is to build a unified ESG data infrastructure that can serve both BRSR and CSRD requirements. Start with BRSR compliance as your foundation, then layer CSRD-specific requirements (double materiality, ESRS-aligned disclosures, enhanced Scope 3 accounting) on top. This avoids duplicate data collection and creates a single source of truth for sustainability metrics. C² specialises in building integrated ESG reporting frameworks that simultaneously meet BRSR, CSRD, TNFD, and TCFD requirements. Our technology platform streamlines cross-framework data collection and ensures your disclosures are globally credible.
