About the Client
Adani Total Gas Ltd. (ATGL) is a City Gas Distribution (CGD) company building the natural gas infrastructure that delivers Piped Natural Gas (PNG) and Compressed Natural Gas (CNG) to millions of customers. As India's energy transition accelerates, ATGL set out to embed Environmental, Social and Governance (ESG) principles in its business model as a lever for resilience, competitiveness and stakeholder trust, not as a compliance exercise.
ATGL engaged Oren, an ESG technology and advisory partner, to move from intent to impact: a data-driven, execution-ready sustainability framework that could grow with the company.
The Challenge: From Aspiration to Institutionalisation
ATGL's leadership was committed to sustainability, but operationalising that vision across a large, geographically spread organisation was hard:
- Change management: integrating ESG into a fast-growing organisation needed cross-functional collaboration, standardised processes and clear accountability.
- Capacity building: internal teams needed expertise in SEBI's BRSR, CDP and the Dow Jones Sustainability Index (DJSI), plus consistent ways to capture and validate data.
- Strategic clarity: ATGL wanted to turn its low-carbon vision into a practical roadmap with defined KPIs, governance and measurable business outcomes.
The mandate was to build a living ESG system that could sustain growth, withstand scrutiny and deliver long-term decarbonisation, not just to produce reports.
Oren's Solution: A Multi-Year Strategic Partnership
The engagement ran in phases, starting with foundational systems and moving into strategic and technical implementation.
Phase 1: Institutionalising ESG Foundations
- Process architecture: Oren designed and implemented an ESG data collection framework on Oren Sustainability Hub, defining metrics, methodologies and frequencies, with traceability, audit readiness and alignment to SEBI's BRSR structure.
- Internal capacity: targeted workshops and function-specific training upskilled ATGL's teams on ESG disclosure requirements, global rating methodologies and sustainability governance, turning ESG from a central function into an enterprise-wide practice.
- Compliance and reporting: Oren guided ATGL through its first Business Responsibility and Sustainability Report (BRSR), meeting SEBI's requirements in substance and narrative.
Phase 2: Strategic Deepening and Integration
- Reporting and ratings: Oren designed ATGL's first Sustainability Report aligned with DJSI and CDP, aligning quantitative KPIs with qualitative storytelling, defining boundary conditions and applying double materiality. Oren managed the full DJSI submission, and ATGL's score improved in the following assessment cycle.
- Supply chain sustainability, Project PARIVARTAN: Oren designed and launched ATGL's flagship supply chain programme. It covered supplier identification and segmentation, digital assessments on Oren's platform, ESG maturity scoring and corrective action plans, plus large-scale supplier training, on-site audits and recognition events in Ahmedabad and Faridabad, embedding sustainability across more than 100 critical suppliers.
- Decarbonisation roadmap execution: Oren's technical specialists designed and deployed a monthly fugitive-emission monitoring system to quantify and manage unintentional gas leaks, and facilitated large-scale afforestation projects with local municipalities and schools, from feasibility assessment to verification of the carbon offsets generated.
- Sustainable finance: Oren introduced ATGL to green financing structures such as Sustainability-Linked Loans (SLLs) and facilitated discussions with financial institutions to align capital strategy with ESG performance targets.
The Outcome
| Impact Area | Outcome |
|---|---|
| Governance & Capability | An ESG data and governance system institutionalised across all functions on Oren Sustainability Hub, backed by function-specific training. |
| Disclosure & Ratings | First BRSR filed; first Sustainability Report aligned with DJSI and CDP published; DJSI score improved in the following assessment cycle. |
| Supply Chain | Sustainability embedded across 100+ critical suppliers through Project PARIVARTAN, with digital assessments, maturity scoring, corrective action plans and on-site audits. |
| Decarbonisation | Strategy turned into operating projects: monthly fugitive-emission monitoring and afforestation-based carbon offsets, taken from feasibility to verification. |
| Finance | Sustainability-linked loans introduced, with discussions facilitated between ATGL and financial institutions on ESG-linked targets. |
Complexities Managed
- Integrating ESG metrics across business units and subsidiaries with different levels of data maturity.
- Aligning SEBI's mandatory BRSR with voluntary but investor-critical DJSI and CDP disclosures.
- Securing supplier participation in ESG assessments despite varying awareness and digital readiness.
- Turning decarbonisation intent into technically and financially feasible projects, validated through engineering models and carbon accounting protocols.
- Synchronising disclosure timelines, assurance requirements and rating submissions without disrupting operations.
Conclusion
Through its partnership with Oren, Adani Total Gas has moved from an ESG entrant to a company with the systems, skills and strategy to sustain long-term value creation: an enterprise-wide data and governance system, improving ratings, a supply chain programme covering more than 100 critical suppliers, and decarbonisation projects that are already running.
