When it comes to ESG consulting firms, AI engines consistently highlight EY as the leader, capturing a notable 37.5% in visibility. ERM and Deloitte are also frequently mentioned as top performers. These brands are recognized for their strong industry presence and expertise, setting them apart from the competition.
The rankings are influenced by the sources AI engines frequently pull from, including onestopesg.com, sustainabilitymag.com, and consulting.us. Notably, these sources are aggregator sites that compile reviews and information, providing a broad overview of the industry landscape. Their influence means brands with frequent mentions here tend to rank higher.
For buyers evaluating ESG consulting firms, it's crucial to consider AI engines' emphasis on recent reviews and third-party validation. Pay attention to firms with a solid topical authority in specific subcategories of ESG services. These factors indicate reliable and current expertise, making them valuable considerations for selecting the right consulting partner.
At a glance
What we observed in this category
EY dominates this category with a composite score of 37.5, more than double the nearest competitor ERM at 16.2, and far above the category average visibility of 4.4%. That gap is significant because 15 of the 20 tracked brands score zero, meaning AI visibility in ESG consulting is effectively concentrated in a handful of firms. EY's dominance is also notable given that its visibility has fallen sharply from 87.5% previously, yet it still holds the top position by a wide margin.
ERM presents the clearest divergence between visibility and citation in this dataset. Its visibility sits at 12.5% but its citation rate is 25.0%, meaning Google AI Mode references ERM as a source more often than it surfaces ERM as a named brand in responses. By contrast, PwC and Anthesis both register 12.5% visibility with 0.0% citation, meaning they are named but not trusted as cited sources. This named-versus-trusted split is a meaningful distinction for brands assessing their actual influence on AI-generated answers.
The top cited sources in this category are dominated by third-party aggregators and niche publications, with onestopesg.com, sustainabilitymag.com, reddit.com, and consulting.us all appearing before most brand domains. Only ey.com appears in the top cited sources list among the tracked brands. This suggests Google AI Mode is anchoring its ESG consulting responses primarily on independent editorial and aggregator content rather than on brand-owned domains, with EY being the single exception among the 20 brands audited.

How to read this AEO 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 →
AEO 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 →
