Executive Summary
ESG (Environmental, Social, Governance) due diligence has evolved from a "nice-to-have" to an essential component of M&A transactions in India. With SEBI's Business Responsibility and Sustainability Reporting (BRSR) requirements, increasing lender focus on ESG, and growing liability for environmental and social violations, acquirers ignore ESG at their peril. This article provides a practical framework for ESG due diligence in Indian M&A, covering key areas, red flags, and deal structuring considerations.
Key Drivers:
- SEBI BRSR mandatory for top 1,000 listed companies
- Lender ESG covenants increasingly common
- Environmental liabilities can be material
- Social issues create reputational and operational risk
- Governance failures lead to post-acquisition surprises
Introduction
When Tata Steel acquired Bhushan Steel, the deal included not just manufacturing assets but also environmental liabilities, labor issues, and governance problems. When Hindustan Unilever acquired GSK Consumer Healthcare, ESG alignment was a positive factor in integration.
ESG due diligence is no longer about ticking boxes - it's about understanding risks that can make or break a deal.
Section 1: Why ESG Due Diligence Matters in India
The Indian ESG Landscape

Section 7A: Key Judicial Precedents for ESG Due Diligence
Labour Law Cases Relevant to Social DD
1. BHEL v. State of U.P. (2003) - Supreme Court
| Aspect | Details |
|---|---|
| Citation | Appeal (civil) 2459-2461 of 1999 |
| Judges | Justice Shivraj V. Patil, Justice D.M. Dharmadhikari |
| Date | 21-07-2003 |
Issue: Whether BHEL was the employer of gardeners engaged through a contractor.
Holding: The Supreme Court applied the control test and found BHEL was the true employer:
- BHEL exercised direct supervision
- Maintained attendance records
- Had managerial involvement
"When a contractor's engagement is a sham, the principal employer is deemed to be the real employer."
DD Implication: Acquire must assess whether contract labour arrangements are genuine or sham - potential liability for regularization and back-wages.
2. NTPC v. Karri Pothuraju (2003) - Supreme Court
| Aspect | Details |
|---|---|
| Citation | Appeal (civil) 5990 of 1997 |
| Judges | Justice S. Rajendra Babu, Justice Doraiswamy Raju |
| Date | 13-08-2003 |
Issue: Whether canteen workers engaged by contractors are entitled to regularization as NTPC employees.
Holding: Where statutory obligation exists (Section 46, Factories Act) to maintain canteen, workers are employees of principal employer regardless of contractor arrangement.
DD Implication: Statutory obligations (canteen, security, etc.) create employer liability for contractor workers. Check all such arrangements in target company.
M&A/Takeover Cases
3. Harinarayan G. Bajaj v. Union of India (2007) - Bombay HC
| Aspect | Details |
|---|---|
| Citation | WP/174/1998 |
| Judges | Justice J.N. Patel, Justice A.A. Sayed |
| Date | 26-11-2007 |
| Designation | Land Mark Judgment |
Issue: Whether indirect acquisition of control through a holding company triggers SEBI Takeover Regulations.
Holding: Indirect acquisitions via holding company do not trigger 1994 Take-Over Regulations if no shares of listed target are directly acquired.
"The narrow scope of the 1994 Regulations excluded indirect control through an unlisted holding company."
DD Implication: Structure of acquisition matters for regulatory triggers. Indirect holdings require careful analysis under current SAST Regulations (which have since been amended).
Environmental Liability Cases
4. AP Pollution Control Board v. CCL Products (2019) - Supreme Court
| Aspect | Details |
|---|---|
| Citation | Civil Appeal No. 7005 of 2017 |
| Date | 22-07-2019 |
DD Implication: Environmental bank guarantees are readily enforceable. Verify all guarantees given by target and ensure these are factored into deal pricing.
Governance/FEMA Cases
5. ND Investments v. Union of India (2015) - Bombay HC
| Aspect | Details |
|---|---|
| Citation | NMAL.168.2015 |
| Judges | Justice S.C. Dharmadhikari, Justice Sunil P. Deshmukh |
| Date | 21-01-2015 |
Issue: FEMA violations for remittances made before establishing Indian subsidiary.
Holding: Court reduced pre-deposit requirement but affirmed that FEMA violations carry serious penalties. Tribunals must consider prima facie hardship.
DD Implication: FEMA compliance history is critical for targets with foreign investment. Historical violations may result in pending penalties or show-cause notices.
Due Diligence Checklist Enhancement Based on Case Law
| Case Law Issue | DD Action Item |
|---|---|
| Sham contractor arrangements | Review all contractor agreements; assess control tests |
| Statutory obligation workers | Verify canteen, security, housekeeping arrangements |
| Indirect acquisition structure | Map holding structure for regulatory triggers |
| Environmental guarantees | List all bank guarantees; factor into valuation |
| FEMA compliance history | Review all foreign investment history; check for SCNs |
Escrow and Holdback
When to Use:
| Situation | Escrow Approach |
|---|---|
| Identified contamination | Specific amount based on remediation estimate |
| Pending environmental litigation | Expected liability + buffer |
| Labor disputes | Settlement estimate + legal costs |
| Compliance gaps | Remediation cost estimate |
Price Adjustment
ESG-Related Adjustments:
Price Adjustment Framework:
QUANTIFIED LIABILITIES:
├─ Known remediation costs → Deduct from price
├─ Pending litigation → Discount by probability-weighted liability
├─ Compliance capex needed → Deduct NPV of required spend
UNQUANTIFIED RISKS:
├─ General ESG weakness → Overall discount negotiation
├─ Transition risk → Scenario-based adjustment
├─ Reputational concerns → Strategic value adjustment

- Protect in Docs: Strong warranties, indemnities, escrows
For Sellers
- Pre-DD Preparation: ESG data room readiness
- Address Known Issues: Fix fixable problems before sale
- Disclosure Approach: Full disclosure reduces post-closing risk
- BRSR Compliance: Demonstrate ESG maturity
- Narrative: Tell positive ESG story proactively
For Advisors
- Integrated Approach: Don't silo ESG from other DD
- Sector Expertise: ESG issues vary by industry
- Quantification: Help clients value ESG factors
- Deal Terms: Draft appropriate protections
- Integration Support: Continue beyond closing
Conclusion
ESG due diligence in Indian M&A has transitioned from optional to essential. Key takeaways:
| Aspect | Implication |
|---|---|
| Regulatory drivers | BRSR, CCTS, NGT make ESG compliance measurable |
| Liability exposure | Environmental, social liabilities can exceed deal value |
| Value creation | Strong ESG enables synergies; weak ESG requires investment |
| Deal structuring | Proper warranties, indemnities, escrows protect acquirers |
| Integration | ESG alignment needed from Day 1 |
The acquirer who skips ESG due diligence may save time and cost in the short term - but risks purchasing problems that will cost multiples more to fix later.
For sellers, ESG-ready companies command premiums; those with ESG gaps face discounts or deal failure.
ESG due diligence is not about being virtuous - it's about being smart.
