Introduction: India’s ESG Shift from Company Boundaries to Ecosystem Accountability
Over the last few years, ESG in India has largely been understood through the lens of corporate self-disclosure. With the introduction of the Business Responsibility and Sustainability Report (BRSR), companies focused on building internal data systems, aligning departments, and learning how to disclose environmental, social, and governance performance within their own organisational boundaries. That phase is now decisively ending.
India’s ESG ecosystem is entering a new stage one where sustainability performance is no longer assessed only within factory walls or office premises, but across the entire business ecosystem. Regulators, investors, and global value-chain partners increasingly recognise a fundamental reality: the majority of environmental and social risks associated with businesses do not sit in corporate headquarters; they sit in supply chains.
Greenhouse gas emissions are largely embedded in purchased goods and logistics. Labour risks often arise at contractor and supplier sites. Water stress, waste mismanagement, safety incidents, and compliance failures frequently originate outside direct operations. It is this reality that the next phase of BRSR seeks to address.
With the expansion of BRSR Core and the growing regulatory focus on value chain disclosures, Indian companies are now being pushed towards ecosystem-level accountability. FY 2025–26 becomes a turning point not because a new format will apply, but because the nature of ESG itself is changing. Sustainability is no longer something a company “has.” It is something a company must now “build and govern” across its business relationships.
Why Value Chain Reporting Is Becoming Inevitable
Globally, ESG regulation is moving in one clear direction: upstream and downstream accountability. Whether it is Scope 3 emissions, human rights due diligence, responsible sourcing requirements, or climate risk management, the message from regulators and capital markets is consistent, corporate responsibility does not end at the organisational boundary.
India’s approach through BRSR reflects this global evolution. While early ESG disclosures helped establish transparency, regulators have now turned their attention to credibility, completeness, and impact. Without value chain integration, sustainability disclosures remain partial and often misleading.
From an environmental perspective, for most manufacturing, FMCG, pharmaceutical, infrastructure, and technology companies, over 70% of emissions sit in the value chain. Water stress is often linked to raw material regions, not corporate campuses. Waste and packaging impacts largely arise downstream. From a social lens, contractor safety, migrant labour, working hours, wage practices, and grievance redressal often sit with vendors rather than payroll employees. Governance risks such as corruption, data misuse, and regulatory non-compliance frequently emerge through third parties.
In this context, value chain ESG reporting is not an optional enhancement. It is a structural necessity.
The gradual expansion of BRSR Core metrics toward value chain coverage reflects this inevitability. Over time, Indian listed entities will increasingly be expected to demonstrate that they understand, monitor, influence, and improve ESG performance not just internally, but across their significant business relationships.
What “Value Chain Partner Reporting” Actually Means in Practice
There is widespread misunderstanding around value chain reporting. It does not mean collecting data from every small vendor overnight. It means moving from a company-centric ESG model to a risk-based, prioritised, structured ecosystem model.
Under BRSR Core, value chain focus will gradually require companies to:
- Identify key upstream and downstream partners
- Prioritise them based on spend, risk, dependency, geography, and material ESG exposure
- Begin structured engagement, data collection, and monitoring
- Build systems to consolidate and validate partner-level ESG data
This includes, over time, capturing information such as:
Environmental parameters
Energy use, renewable share, emissions, water withdrawal and discharge, waste management practices, hazardous material handling, environmental permits, and regulatory compliance.
Social parameters
Number of workers, contract labour composition, wage structures, working hours, occupational health and safety systems, accident records, welfare facilities, and grievance redressal mechanisms.
Governance parameters
Codes of conduct, anti-bribery systems, compliance maturity, data protection practices, audit mechanisms, and ethical reporting channels.
Critically, this information will need to move from anecdotal confirmations to structured, documented, and progressively verifiable datasets.
This is why value chain reporting is fundamentally not a sustainability team project. It is an organisational transformation exercise.
Why This Is Not Merely a Reporting Change
Many companies initially approach BRSR value chain expansion as a documentation challenge. In reality, it is an operating-model challenge.
Supplier ESG data cannot be collected without contractual rights, onboarding processes, training systems, internal ownership, digital tools, and senior management backing. Procurement teams are not traditionally designed to manage ESG performance. Legal agreements rarely contain sustainability clauses. Vendors are often selected purely on cost, quality, and timelines, not ESG maturity.
Once value chain reporting begins, companies immediately confront questions such as:
- Who owns supplier ESG engagement internally?
- What happens if suppliers cannot provide data?
- How is data verified?
- How are non-compliances handled?
- How do we support MSME suppliers without disrupting business continuity?
- How do ESG risks influence sourcing decisions?
These questions shift ESG from reporting into governance, risk management, commercial negotiations, and operational control.
This is why value chain reporting cannot be approached reactively. Without early system-building, companies risk fragmented efforts, inconsistent data, supplier resistance, and reputational exposure.
The Current Reality of Indian Supply Chains
Across most Indian sectors today, supplier ESG maturity remains uneven.
Large Tier-1 suppliers may have certifications, policies, and EHS systems. However, deeper tiers often operate with minimal documentation, limited formal controls, and low awareness of ESG expectations. Many MSMEs do not measure energy, emissions, or water. Social compliance may rely on statutory registers without structured monitoring. Governance systems are frequently informal.
At the same time, Indian corporates themselves often lack:
- Centralised supplier ESG databases
- Standardised ESG questionnaires
- Internal ESG risk scoring frameworks
- Supplier training programs
- Defined escalation and remediation pathways
As a result, when value chain disclosures begin, companies often struggle even to define what information they should ask for, let alone how to collect and manage it.
This gap between regulatory expectations and operational readiness is precisely why FY 2025–26 is so critical. It is not the year to start reporting. It is the year to start building.
What Indian Companies Must Start Doing Now
The transition to value chain ESG integration requires a phased, structured roadmap.
The first step is value chain mapping and risk prioritisation. Companies must understand who their critical partners are, where major ESG risks sit, and which relationships matter most from both business and sustainability perspectives. This allows focused effort rather than indiscriminate data collection.
The second step is governance design. Organisations must establish cross-functional ownership structures involving sustainability, procurement, legal, compliance, operations, and IT. Clear roles, escalation mechanisms, and leadership oversight are essential.
The third step is supplier ESG onboarding. This includes drafting supplier codes of conduct, integrating ESG clauses into contracts, designing ESG questionnaires, and communicating expectations clearly and progressively.
The fourth step is capacity building. Suppliers must be supported through guidance documents, training sessions, helplines, and pilot programs. Without supplier enablement data quality and compliance will remain weak.
The fifth step is data architecture. Whether through digital platforms or structured internal systems, companies must build mechanisms for collecting, validating, consolidating, and reporting supplier ESG data. Audit trails, document storage, and review workflows will become increasingly important.
Finally, companies must design improvement and remediation pathways. Value chain ESG is not about eliminating all non-compliances immediately. It is about identifying risks, supporting improvements, tracking progress, and integrating sustainability into sourcing strategies over time.
Why Early Movers Will Gain a Strategic Advantage
Companies that start building value chain ESG systems early will gain advantages on multiple fronts.
From a regulatory perspective, they will be better prepared for future expansions of BRSR Core and allied ESG regulations. From an investor perspective, they will demonstrate credible risk management and governance maturity. From a commercial perspective, they will be better positioned to serve global customers increasingly demanding traceable and responsible supply chains.
Operationally, early engagement reduces disruption, allows phased implementation, and builds trust with suppliers. Strategically, it enables companies to shift from reactive compliance to proactive sustainability leadership.
Most importantly, it transforms ESG from a reporting burden into a resilience and value-creation lever.
Conclusion: Value Chain Readiness Will Define ESG Leadership in India
India’s ESG journey is entering its most complex and consequential phase. The expansion of BRSR Core toward value chain accountability reflects a broader global transition from transparency to responsibility, from disclosure to governance, from corporate boundaries to ecosystems.
For Indian companies, FY 2025–26 is not about filling new tables. It is about building new capabilities. Those who use this period to design systems, engage partners, and embed ESG into commercial and operational foundations will shape the next generation of responsible business leadership.
Value chain readiness will not merely determine reporting quality. It will determine credibility, competitiveness, and long-term sustainability.
