The Urgency

Most Companies Aren't Ready for Assurance

SEBI has accelerated timelines, but data infrastructure, governance processes, and internal controls lag far behind requirements.

A significant proportion of top 500 companies lack the ESG data systems, internal controls, and evidence trails needed for third-party assurance (industry observation).

Questions

Frequently Asked Questions

What exactly is BRSR Core and why does it need assurance?+

BRSR Core is a subset of 9 ESG attributes (49 KPIs) identified by SEBI as the most critical indicators. Unlike regular BRSR disclosure (self-reported), BRSR Core requires "reasonable assurance" from an independent assurance provider — similar to a financial audit. This means your ESG data must meet the same rigour standards as your financial statements.

Is my company required to do BRSR Core assurance?+

If you are among the top 500 listed companies by market capitalisation, BRSR Core assurance is already mandatory for FY 2025-26. For companies ranked 500-1,000, it becomes mandatory from FY 2026-27. This is the final step — all top 1,000 companies will be under assurance by next year.

Can we really get assurance-ready in just 12 weeks?+

The 12-week timeline is achievable for companies with existing data collection practices and dedicated client-side coordination. For companies with very low ESG maturity, we may recommend a 16-week extended programme. The diagnostic phase (Weeks 1-3) will determine the right timeline for your organisation. Readiness depends on the quality of your starting data and the responsiveness of internal teams — the programme defines the review procedures, not a guaranteed outcome.

Do you provide the actual assurance, or prepare us for it?+

This programme prepares your data, controls, and evidence for assurance — it does not include the assurance opinion itself. The final reasonable assurance opinion must come from an eligible independent assurance provider appointed directly by your company, in accordance with SEBI's requirements. Your company is responsible for selecting and engaging the assurance provider. Our mock audit simulates the assurance process to help identify and close gaps before the formal engagement.

What is the payment structure?+

Payments are milestone-based, tied to deliverables: 30% at engagement signing, 25% after diagnostic completion (Week 3), 25% after data architecture & collection (Week 8), and 20% after mock audit & final deliverables (Week 12). This ensures you pay as value is delivered.

What happens after the 12-week sprint?+

All tiers include post-sprint support (60-180 days depending on tier). During this period, we can support you in responding to queries from your independently appointed assurance provider and help remediate any findings. Note: RSustain does not appoint the assurance provider on your behalf. Your company must directly engage an eligible independent assurance provider in accordance with SEBI requirements.
