When AI engines like ChatGPT, Claude, Perplexity, and Gemini answer questions about ESG consulting firms, EY comes up in 87.5% of responses, making it the clear frontrunner in this category. ERM and Deloitte follow as the next most-cited brands across the 20 firms tracked. If you are shortlisting firms based on market presence, those three names dominate the conversation AI engines are having with buyers like you.
The rankings reflect which sources AI engines pull from most heavily. The top cited domains include sustainabilitymag.com, managementconsulted.com, and onestopesg.com, a mix of trade publications and aggregator or listicle-style sites. When aggregators dominate citations, it means a firm's visibility depends heavily on being featured in roundup articles and third-party rankings, not just on its own website or thought leadership content.
For a buyer using this page to shortlist firms, pay attention to which brands appear consistently across multiple third-party sources, not just which firm has the biggest brand. AI engines weight recent coverage, external validation, and topical specificity, so a firm with strong reviews on aggregator sites and published work on your specific ESG subcategory (climate risk, supply chain, reporting frameworks) will likely serve you better than one riding on general brand recognition alone.
At a glance
What we observed in this categoryauto-generated
EY dominates the ESG consulting AI visibility landscape with a 87.5% visibility score, more than three times higher than any competitor and well above the category average of 10.0%. The next closest brands, ERM, Deloitte, and PwC, each sit at 25.0% visibility. This gap is structurally significant because it means AI-generated responses to ESG consulting queries reference EY in nearly nine out of every eight query sets, while most other large firms appear only occasionally or not at all.
ERM presents the clearest divergence between being named and being cited. Its citation rate of 37.5% is the highest in the category, yet its visibility is only 25.0%, matching Deloitte and PwC. PwC, by contrast, holds 25.0% visibility but a 0.0% citation rate, meaning AI responses mention PwC without linking to its domain. Anthesis shows the sharpest version of this pattern, earning a 25.0% citation rate with zero visibility, suggesting AI treats it as a credible source without naming it in answer text.
Google AI Mode is the sole top engine recorded for every brand in this dataset, confirming that the entire competitive dynamic in ESG consulting AI visibility plays out on a single platform. The top cited external sources include sustainabilitymag.com, managementconsulted.com, and linkedin.com, none of which are brand-owned properties for the ranked firms. ERM is the only ranked brand whose own domain (erm.com) appears in the top cited sources list, giving it a structural citation advantage that its composite score of 28.8 partially reflects.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically. How AI search ranking works →
