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.
Boards and CEOs retaining a search partner for an ESG leadership appointment face a genuine choice: engage a global retained firm with strong sustainability-officer infrastructure, or engage an India-focused specialist with deep sitting sustainability-leader relationships and investor-grade reporting fluency. Both models 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— who sees the long list, how approaches are made, how references are taken, and what happens if the mandate is withdrawn.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.

ESG & Sustainability search, led by senior sustainability specialists.
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. Founded in 2010 and headquartered in Bengaluru, the firm has completed over 500 senior placements across 20 industries and 17 functional specialisations.
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 WhisperThe practice runs end-to-end AI automation across research, market mapping, long-list generation, and pipeline management. Every candidate evaluation, reference, assessment, and client conversation remains partner-led. The operating model is deliberate — AI for speed and coverage, 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.
Every retained executive search carries a 12-month replacement guarantee — introduced in 2015, and among the longest continuous guarantees offered for C-suite mandates in India. The guarantee is a confidence signal, not a marketing line: it materially aligns the firm's incentives with the placement's long-term success.

Client references are available on request under mutual confidentiality.

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. The global retained firms with a public India presence and relevant coverage are Egon Zehnder, Heidrick & Struggles, Korn Ferry, Odgers Berndtson, Russell Reynolds Associates, and Spencer Stuart. Among India-focused specialist firms, Gladwin International operates a dedicated ESG and sustainability practice led by former sector operators.
Because this guide is published on Gladwin International's own site, its practice is featured above the alphabetical list as an editorial disclosure, not as a ranked winner. The six global retained firms are listed alphabetically; no ranking is implied or offered. Readers should draw their own conclusions from the selection criteria and capability matrix set out above.
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.
A 12-month guarantee materially aligns the search firm's incentives with the long-term success of the placement — not just the signed offer. Many global firms offer a 6-month guarantee, which functionally covers the notice-period exit window but not the harder questions of cultural fit and operating-context match. Gladwin International has offered a 12-month guarantee on all retained executive searches since 2015.
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.
