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

Development Year Impact
SEBI BRSR mandatory 2023 (top 1000) Standardized ESG disclosure
BRSR Core 2024 Assurance requirements
Green Taxonomy 2025 (draft) Climate financing standards
NGT active enforcement Ongoing Environmental liability risk
Labor code reforms 2020 (not fully implemented) Compliance complexity
POSH Act enforcement 2023 amendments Social compliance scrutiny

Deal-Breaker Potential

Environmental:

  • Pollution control violations → Operating license risk
  • Hazardous waste non-compliance → Criminal liability
  • Climate litigation exposure → Stranded asset risk
  • Forest/environmental clearance gaps → Project viability

Social:

  • Labor disputes → Business disruption
  • POSH violations → Management liability
  • Community opposition → Project delays
  • Supply chain issues → Reputational damage

Governance:

  • Related party transactions → Value leakage
  • Board composition issues → Regulatory non-compliance
  • Anti-corruption gaps → FCPA/UK Bribery Act exposure
  • Whistleblower retaliation → Cultural problems

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

Section 8: Post-Acquisition Integration

100-Day ESG Plan

Section 9: Recommendations

For Acquirers

  1. Start Early: ESG DD from preliminary stage
  2. Engage Specialists: Technical expertise for environmental sites
  3. Materiality Focus: Prioritize deal-breakers; don't boil ocean
  4. Integration Planning: Build ESG into Day 1 planning
  5. Protect in Docs: Strong warranties, indemnities, escrows

For Sellers

  1. Pre-DD Preparation: ESG data room readiness
  2. Address Known Issues: Fix fixable problems before sale
  3. Disclosure Approach: Full disclosure reduces post-closing risk
  4. BRSR Compliance: Demonstrate ESG maturity
  5. Narrative: Tell positive ESG story proactively

For Advisors

  1. Integrated Approach: Don't silo ESG from other DD
  2. Sector Expertise: ESG issues vary by industry
  3. Quantification: Help clients value ESG factors
  4. Deal Terms: Draft appropriate protections
  5. 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.
