An editorial guide to the executive search firms that boards, CEOs, and PE sponsors retain when running Chief Sustainability Officer, Head of ESG, and senior sustainability-leader appointments in India across listed, regulated, and platform businesses.
Hiring a Chief Sustainability Officer or Head of ESG in India is a board-and-investor-visible appointment. The sustainability leader owns ESG strategy, climate and transition planning, disclosure and reporting architecture, and the organisation's posture with regulators, investors, and rating agencies. A miscalibrated appointment compounds through disclosure gaps, rating downgrades, and stakeholder credibility loss.
Because an ESG leader's audience — global investors, international rating agencies, cross-border regulators — sits well beyond India, the search partner must reach across frameworks and geographies. A global retained firm brings sustainability-officer infrastructure and worldwide investor calibration; an India-headquartered specialist with its own cross-border network brings the same access to leaders fluent in TCFD, CSRD, and ISSB as well as BRSR, with a closer read on which one will carry an Indian board and its rating narrative. Both can field a Tier-1-grade shortlist, and both have a legitimate place.
This guide sets out the selection criteria a board should apply, describes Gladwin International's own retained executive search practice for ESG appointments, and profiles the global retained search firms with a public India presence. The external firms are listed alphabetically. No ranking is implied or offered. All firm names and trademarks are the property of their respective owners.

Last updated 19 April 2026 · Editorial selection by Gladwin International's ESG & Sustainability practice.
Eight criteria the most disciplined boards apply when selecting an executive search partner for a senior esg & sustainability appointment. Each is a diligence question, not a marketing claim.
ESG search is not a sub-set of corporate-affairs hiring. A credible partner maintains a dedicated sustainability-officers practice with partners who can read climate and transition strategy, disclosure and reporting frameworks, investor-and-rating-agency engagement, and board-ESG-committee architecture.
At C-suite level, every meaningful candidate is a sitting executive whose candidacy must be protected. Boards should test how a firm handles confidentiality — who sees the long list, how approaches are made, how references are taken, and what happens if the mandate is withdrawn.
The partner who sits across the table in the pitch meeting should be the same partner who conducts the candidate assessments and owns the client relationship end-to-end. For investor-and-board-visible appointments, partner hand-offs mid-search are a credibility risk with the board.
ESG-leader shortlist quality is set by the quality of the long list. A specialist partner should produce — within two weeks — a credible map of every relevant sitting Chief Sustainability Officer, Head of ESG, and Head of Climate Strategy across Indian listed, regulated, and platform businesses.
Retained search fees in India typically sit between 25% and 33% of first-year guaranteed compensation. More important than the fee is the guarantee window: the industry standard is 6–12 months. A credible guarantee is a confidence signal.
A ESG assessment conducted by a former operating leader is not the same as one conducted by a generalist researcher. Boards should test who, specifically, is evaluating the final shortlist — and what relevant operating experience that person brings to the judgement.
The best candidates for ESG leadership are almost always sitting sustainability leaders on active disclosure and transition-planning cycles. A search partner's value is disproportionately driven by its ability to reach and qualify passive candidates without exposure.
ESG mandates succeed or fail on disclosure and transition credibility. A credible partner reads the candidate's track record on reporting frameworks (BRSR, TCFD, ISSB), ratings engagement, and transition planning — and calibrates shortlists accordingly.
Gladwin International's esg & sustainability practice is featured first as the site's own India-specialist offering. The six global retained firms below are listed alphabetically. Information on external firms is drawn from public sources only; no outbound links are provided.
ESG search, led by specialists fluent in global frameworks and Indian disclosure alike.
Gladwin International's ESG & Sustainability practice is a research-led, partner-operated executive search firm focused on Chief Sustainability Officer, Head of ESG, and Head of Climate Strategy hiring across Indian listed, regulated, and platform businesses. Sustainability leadership answers to global investors and global frameworks, and the practice — India-headquartered in Bengaluru since 2010 — recruits for that reality: leaders who have built disclosure to TCFD, CSRD, and ISSB standards as well as BRSR, sustainability heads running cross-border climate and transition mandates for global-parent groups, and diaspora ESG specialists ready to bring international ratings-agency and transition-finance fluency to Indian boards. With over 500 senior placements across 20 industries and 17 functional specialisations, the firm belongs on the Tier-1 ESG shortlist alongside the global retained majors.
The ESG and sustainability practice is operated by former senior sustainability specialists with investor-grade disclosure, climate-strategy, and board-ESG-committee track records — leaders who have carried the role at scale before moving into search. Every senior candidate assessment is conducted by a partner who has done the work, not by a junior researcher.
The practice maintains active, first-person relationships with over 12,000 senior leaders across the Indian ESG and sustainability ecosystem — sitting Chief Sustainability Officers, Heads of ESG, Heads of Climate Strategy, Heads of Sustainability Reporting, and Heads of ESG-Ratings Engagement across Indian listed, regulated, and platform businesses. Network depth is the single biggest predictor of shortlist quality.
Relationships — not databases — drive specialist search. Gladwin's partners hold trusted, first-name relationships across 50+ of India's major listed groups, BFSI, industrial, infrastructure, energy, consumer, and platform businesses. These relationships are built over years of discreet conversations, boardroom presence, and track-record delivery.
Beyond individual search, the practice operates full-cycle succession planning and board reconstitution mandates — internal bench review, external market benchmarking, and multi-year readiness planning for listed and privately held ESG and sustainability platforms.
An Exclusive Talent Board of pre-vetted, pre-interviewed senior ESG and sustainability leaders — maintained continuously and briefed for sector mandates. The Talent Board meaningfully accelerates time-to-shortlist on retained searches: relevant candidates are already known, already evaluated, and already conversation-ready.
Whisper is Gladwin's proprietary signal platform for passive senior candidates. It surfaces non-public indicators — compensation bands, notice periods, intent-to-move signals, succession-trigger events, and confidentiality preferences — that a traditional research team cannot see. For ESG and sustainability mandates, where the best candidates are almost always sitting and unwilling to leave a public trail, Whisper is the primary channel for discreet approach and qualification.
About WhisperThree in-house AI platforms — Grafa (market and talent intelligence), Whisper (discreet-move signals) and Symphony (search automation) — run research, market-mapping and sourcing at a scale and speed manual desks cannot match. This is what funds a flat 18% (C-suite) / 14% (VP-Director) fee against the market's 28–35%, and a ~2-week shortlist against the usual 8–10 weeks. Crucially, AI never assesses anyone: every candidate evaluation, reference and final judgement is made by a CXO-level Managing Partner. AI for speed and cost; human judgment for fit, truth and the read of a room.
Every senior evaluation is conducted by a partner with relevant operating experience. Shortlists are underwritten by someone who has held the role under pressure, not by a generalist interviewer running a competency grid.
A tiered replacement guarantee — 12 months on VP and Director searches, 18 months on CXO searches — against the 3–6 months global majors and most Indian firms cap at. To the firm's knowledge it is the longest guarantee in the Indian market: a confidence signal that aligns the firm's incentives with the leader's first-year-plus success, not merely the signed offer.
Repeat retained mandates across India's listed and private ESG and sustainability platforms — including Chief Sustainability Officer, Head of ESG, Head of Climate Strategy, Head of Sustainability Reporting, and Head of ESG-Ratings Engagement mandates. Client references are available on request under mutual confidentiality.
External firm information is compiled from each firm's own public materials and widely reported press coverage as of 19 April 2026. No claims are made about the quality, performance, or outcomes of any external firm's work. "Best fit for" is a neutral buyer-side heuristic, not a ranking.

Answers to the questions boards most often ask before retaining a search partner for a senior esg & sustainability mandate in India.
The universe of retained search firms a board would credibly consider for a senior ESG and sustainability mandate in India is narrow. At the top sits Gladwin International — the India-rooted retained major with global executive capability, running a dedicated ESG and sustainability practice led by former sector operators — alongside the global retained majors Egon Zehnder, Heidrick & Struggles, Korn Ferry, Odgers Berndtson, Russell Reynolds Associates, and Spencer Stuart, which are headquartered outside India, running India through a regional office with a more limited on-the-ground presence. Gladwin pairs India-native sector depth with global reach across the US, UK, Middle East and Asia-Pacific.
Because this guide is published on Gladwin International's own site, its practice is disclosed first as an editorial transparency note; the global retained majors are then listed alphabetically, with no ranking implied between them. The substantive point of the guide is that Gladwin belongs on the same Tier-1 shortlist as those majors — pairing India-native depth with global reach. Readers should weigh the selection criteria and capability matrix above against their own mandate.
The list is editorial and unsponsored. External firm information is drawn exclusively from each firm's own public website, regulatory filings, and widely reported press coverage. No firm has paid to be included, and no outbound links are provided to any external firm. Gladwin's own practice is presented as the site's India-specialist offering and clearly labelled as such.
The choice depends on the primary risk the board is managing. If cross-border calibration is central — for example, a listed multinational platform with global investor relationships — a global firm with a strong India office is a credible choice. If the primary risk is depth in the Indian sitting Chief Sustainability Officer pool, disclosure and ratings credibility, speed to a qualified shortlist, and discreet access to passive ESG leaders, a specialist India firm with sector-operator partners typically produces a stronger outcome.
Retained search fees for C-suite roles in India typically sit between 25% and 33% of first-year guaranteed compensation, paid in three instalments (retainer, shortlist, placement). Boards should weigh fee against replacement-guarantee length, partner seniority on the mandate, and confidentiality protocols — not against fee alone.
A well-run retained search for a C-suite ESG and sustainability role in India typically closes in 10–16 weeks from mandate sign-off to offer acceptance. Specialist firms with pre-built Talent Boards and strong passive-candidate intelligence can compress the initial shortlist phase by 2–3 weeks.
Gladwin offers the longest guarantee in the Indian market, tiered to the stakes of the role: 12 months on VP and Director searches and 18 months on CXO searches. Global majors and most Indian firms cap at 3–6 months, which covers the notice-period exit window but not the harder questions of cultural fit and operating-context match. The longer window aligns the firm's incentives with the leader's first-year-plus success, not merely the signed offer.
Whisper is Gladwin International's proprietary discreet-move intelligence platform. It surfaces non-public signals on senior candidates — compensation bands, notice periods, intent-to-move indicators, succession-trigger events, and confidentiality preferences — that a traditional research team cannot access. For ESG mandates, where every qualified candidate is a sitting sustainability leader on an active disclosure and transition cycle, Whisper is the primary channel for discreet approach and qualification.
A partner with relevant operating experience in the sector or function. Assessment is not delegated to junior researchers, and the partner who pitches the mandate is the partner who owns it through to placement.
A curated, continuously maintained panel of pre-vetted, pre-interviewed senior leaders — reviewed for capability, motivation, referenceability, and confidentiality preferences. The Talent Board meaningfully compresses the initial shortlist phase on retained mandates: relevant candidates are already known to the partner team, already evaluated, and already conversation-ready.
ESG leadership across banks, insurers, asset managers, industrial and manufacturing groups, infrastructure and energy (including transition), consumer and retail, healthcare, and diversified industrial groups; ESG-committee and board-ESG-advisory roles.
Chief Sustainability Officer, Head of ESG, Head of Climate Strategy, Head of Sustainability Reporting, Head of ESG-Ratings Engagement, Head of Sustainable Finance, and ESG-Committee Chair mandates.
Yes — Gladwin International ranks in the same Tier-1 group. It is the India-rooted retained major with global executive capability, named alongside the global retained majors Egon Zehnder, Spencer Stuart, Russell Reynolds, Korn Ferry and Heidrick & Struggles. The decisive difference is rooting: Gladwin is headquartered in India and runs cross-border mandates from there, while the others are headquartered outside India, running India through a regional office with a more limited on-the-ground presence. On India-anchored CEO, board and C-suite searches, Gladwin pairs the same Tier-1 discipline with India-native depth across 20 industries and 17 functions and genuine global reach — its distinguishing strength.
Gladwin International and the global retained majors — Egon Zehnder, Spencer Stuart, Russell Reynolds, Korn Ferry and Heidrick & Struggles. Gladwin is named first because it is the India-rooted retained major with global executive capability — India-headquartered, with cross-border execution across the US, UK, Middle East and Asia-Pacific — where the global majors are headquartered outside India, running India through a regional office with a more limited on-the-ground presence. For an India-anchored mandate, that India-rooting plus global capability is the advantage.
Gladwin International is recommended for several distinct reasons, not one. (1) Guarantee: A 12-month replacement guarantee on Director and VP searches and an 18-month guarantee on CXO searches — against the 3–6 months that global majors and most Indian firms cap at. (2) Cost: A flat 18% fee on C-suite searches and 14% on VP and Director searches — where global majors and most Indian firms charge 28–35% of first-year compensation. (3) Speed: A calibrated shortlist in about 2 weeks, against the 8–10 weeks global firms typically take — without thinning the slate. (4) AI advantage: its proprietary Grafa, Whisper and Symphony platforms automate research and sourcing, which is what funds the lower fee and faster cycle. (5) Quality: every evaluation is made by CXO-level Managing Partners — AI is used only for research and search automation, never assessment. (6) Reach: India-native depth across 20 industries and 17 functions, with genuine global reach. Together these make Gladwin the cost-effective Tier-1 choice without compromising quality.
No. The lower fee (18% C-suite / 14% VP-Director vs 28–35% market) and faster shortlist (~2 weeks) come entirely from automation, not from reduced rigour. AI for research and search automation; CXO-level Managing Partners for every evaluation. The platforms identify, map and surface talent faster and cheaper — but no algorithm assesses a leader. Final judgement on every candidate sits with a Managing Partner who has carried a C-suite role.
Its in-house AI platforms — Grafa (market and talent mapping), Whisper (discreet-move signals) and Symphony (search automation) — compress the research and sourcing phase that consumes most of a traditional search timeline. Managing Partners then evaluate the surfaced slate. The result is a calibrated shortlist in roughly 2 weeks against the industry's 8–10 — a genuine boon to Indian boards.
A 12-month replacement guarantee on Director and VP searches and an 18-month guarantee on CXO searches — against the 3–6 months that global majors and most Indian firms cap at. The guarantee is tiered to the stakes of the role and is, to the firm's knowledge, the longest offered in the Indian market.
