Building ESG Leadership: How India's Sustainability Professionals Develop Skills for C-Suite and Board Roles

There is no established career path to becoming India's Chief Sustainability Officer. Unlike the CFO, whose career progression from chartered accountant to finance manager to VP Finance to CFO follows a well-worn route with clear competency milestones, or the CTO, whose journey from software engineer to engineering lead to VP Technology has predictable waypoints, the CSusO's career trajectory is typically eclectic, cross-disciplinary, and improvised.

This is partly a function of the field's youth: sustainability as a professional discipline is barely 30 years old, and ESG as a corporate governance framework is barely 20. In India, the BRSR mandate is only two years old. There are no IITs with a B.Tech in Corporate Sustainability. The CAs and MBAs who became CFOs had well-established professional development infrastructure; the environmental engineers, corporate lawyers, IAS alumni, and NGO professionals who are becoming CSusOs have had to build their executive credibility through less conventional routes.

But there is a discernible pattern in the career trajectories of India's most successful sustainability leaders — and an emerging clarity about the experiences, credentials, and capabilities that reliably build the competency architecture that boards and CEOs are looking for. Understanding this pattern is valuable for sustainability professionals at every career stage, and for the CHROs and boards responsible for building ESG leadership pipelines.

The Three Archetypes of India's ESG Leaders

Gladwin International's research across 150+ sustainability leadership placements in India identifies three dominant career archetypes that reach CSusO and board-level ESG roles.

The first archetype is the Technical-to-Strategic Transition Leader: typically an environmental engineer, chemical engineer, or climate scientist who built deep technical expertise in environmental compliance, emissions measurement, or process engineering, and then systematically developed commercial, regulatory, and stakeholder management capabilities over a 15-20 year career. Many of India's best CSusOs in energy-intensive sectors (steel, cement, chemicals) follow this path. Their technical credibility is their superpower — the ability to engage substantively with scientists, regulators, and auditors on the actual substance of sustainability commitments — but they must consciously develop the commercial and leadership skills that technical experts often lack.

The second archetype is the Consulting-to-Corporate Transition: sustainability professionals who built their advisory skills at major consulting firms (EY, Deloitte, PwC, KPMG, McKinsey, BCG) or specialised sustainability consultancies (South Pole, ERM, DNV GL, Bureau Veritas), developing deep expertise in sustainability strategy, reporting frameworks, and stakeholder engagement — and then transitioned into corporate leadership roles where they could own and execute the strategies they had previously advised on. This pathway is particularly common among sustainability leaders in financial services, FMCG, and technology companies.

The third archetype is the Business Leader with Sustainability Mandate: a commercial or operational leader — a plant head, a supply chain director, a CFO — who took on sustainability accountability as an extension of their operational role and developed ESG expertise through the practical demands of managing a complex sustainability programme. This archetype is most common in manufacturing and industrial companies where sustainability is deeply embedded in operations, and where the CSusO needs to maintain operational credibility alongside sustainability expertise.

"The CSusOs who have the most impact in Indian industrial companies are those who can sit in a steelmaking operations review and be taken seriously, and then present to a BlackRock ESG analyst and be equally credible. That requires years of deliberate capability building in both directions." — Partner, Gladwin International, ESG & Sustainability Practice, 2025.

The Competency Milestones by Career Stage

For individuals on a sustainability leadership career path, there are identifiable competency milestones at each career stage that predict readiness for the next level.

Early career (0-7 years experience): The priority is deep technical foundation in at least one domain — GHG accounting and carbon markets, environmental compliance and regulatory affairs, sustainability reporting frameworks (GRI, SASB, CDP, BRSR), or social impact and community development. Certifications that build credibility at this stage include the GRI Professional Certification, ISAE 3000 assurance training (for those moving toward sustainability auditing), CDP training on company-level climate disclosures, and the Sustainability Accounting Standards Board (SASB) Fundamentals Certificate.

The single most important early-career experience is working on BRSR assured reporting for a listed company — either in the company's sustainability team or as an assurance provider — because it builds the intersection of regulatory knowledge, data management, and audit-quality documentation that are foundational for senior sustainability leadership.',

Mid-career (7-15 years experience): The priority shifts to developing commercial acumen and cross-functional credibility. The sustainability professional who remains a pure technical specialist at this stage will not make it to C-suite. The experiences that matter most are: taking ownership of a supply chain sustainability programme (which requires engagement with procurement, operations, and supplier management beyond the sustainability function); working on a green bond or sustainability-linked loan transaction (which builds sustainable finance credibility and CFO-level relationships); and managing a major regulator relationship — SEBI engagement for BRSR, MoEF&CC engagement for environmental clearances, or BEE engagement for energy performance standards.

Formal education at this stage should focus on what the career trajectory has NOT naturally provided. Technical leaders should invest in a business education — ISB's sustainability leadership programme, IIM Ahmedabad's executive programme in ESG, or an international degree programme at institutions like Imperial College London's Centre for Climate Finance or the Cambridge Institute for Sustainability Leadership. Commercial leaders moving toward sustainability should invest in technical sustainability training — climate science courses, GHG accounting certification, or TCFD implementation training.

Senior career (15-20 years experience): The priority is building the board-level presence and capital markets credibility that CSusO roles require. Board advisory or committee membership at a non-competing listed entity is the most powerful board-readiness experience — it builds familiarity with board dynamics, board reporting, and the governance expectations that boards have of their executive sustainability leaders.

Sustainable finance experience becomes critical at this stage. Participating in the structuring of a green bond or transition bond — working alongside investment bankers, credit rating analysts, and legal counsel to create a sustainability-linked capital market instrument — builds the financial markets credibility and vocabulary that CSusOs increasingly need. Several India-based sustainability professionals have built this credential through roles at institutions like NABARD (which is a major green bond issuer), SBI (which has issued the largest green bonds in Indian banking), or through sustainability advisory roles at investment banks.

Building India Stack and Regulatory Intelligence

For India's sustainability professionals, one distinguishing competency that is rarely emphasised in global sustainability career frameworks is deep knowledge of India's domestic regulatory and policy architecture — and specifically, how the regulatory environment for sustainability is evolving.

The sustainability professionals who develop direct relationships with India's regulatory institutions — SEBI's sustainability reporting division, MoEF&CC's climate change division, BEE (Bureau of Energy Efficiency), MNRE (Ministry of New and Renewable Energy), and the Expert Committee on Carbon Markets — have access to regulatory intelligence that is simply not available from published guidelines and gazette notifications alone. This intelligence — knowing what is being considered, what is being debated, what is six months away from finalisation — is among the most valuable strategic assets a CSusO can bring to their board and CEO.

Building these relationships is a deliberate career investment. It happens through participation in SEBI technical advisory groups on BRSR evolution, MoEF&CC stakeholder consultation processes on sectoral decarbonisation roadmaps, CII, FICCI, and ASSOCHAM sustainability committees, and ISA (International Solar Alliance) working groups for renewable energy transition professionals.

The Board Director Pathway for Sustainability Leaders

SEBI's listing obligations now require all top-1,000 listed companies to have at least one independent director with ESG-relevant expertise on their board audit committee or, increasingly, on a dedicated sustainability committee. This is creating new board opportunities for experienced sustainability professionals — and a new aspiration for mid-career ESG leaders who are thinking about their 15-year career arc.

The sustainability professionals who are being appointed as independent directors at listed Indian companies typically combine: deep domain credibility (recognised as a thought leader in their sustainability specialisation, having published, spoken at major industry forums, or contributed to regulatory frameworks); commercial orientation (having managed budgets, business relationships, or P&L accountability in their executive career); and governance readiness (having served on audit committees, advisory boards, or sector regulatory bodies in capacities that build board-level judgement).

Gladwin International is increasingly conducting board-level sustainability director searches alongside our CSusO executive search work, and the talent pool — while growing — remains constrained. The sustainability professionals who invest in board readiness development now will be entering a market where demand structurally exceeds supply for the foreseeable future.',

What Organisations Must Do

For Indian companies, the imperative is clear: build the ESG leadership pipeline through structured development, not just external hiring. The external talent market for senior sustainability leadership is thin and intensely competitive. The organisations that will have the strongest ESG leadership teams in five years are those investing in development today.

The most effective organisational development interventions are cross-functional rotation of high-potential sustainability professionals into P&L roles and vice versa; sponsorship of sustainability leaders through board preparation programmes; co-creation with academic institutions (TERI, IIMB's Centre for Corporate Governance and Citizenship, IIT Delhi's Department of Management Studies) on curriculum development and talent development programmes; and structured mentorship of mid-career sustainability professionals by board members with sustainability expertise.',

India's ESG leadership moment has arrived. The companies and professionals who prepare most deliberately for it — who invest in the competency architecture, the regulatory intelligence, and the commercial credibility that C-suite sustainability leadership requires — will define India's corporate sustainability story for the next decade and beyond.
