Verticals

Overview

Environmental Consulting & Engineering covers the advisory and technical services that help clients comply with environmental regulation and manage environmental risk — site assessment, permitting, compliance, impact studies, ESG and sustainability advisory, and remediation engineering. At ~$21B it is led by large diversified firms (AECOM, Tetra Tech, Jacobs, ERM, Stantec) and a fragmented base of specialists.

Demand is driven by environmental regulation, infrastructure and energy projects, climate and ESG reporting, and emerging contaminants (PFAS), with ESG/sustainability and PFAS the fastest-growing practice areas. It is consolidating around scaled multidisciplinary firms and an active M&A arena for environmental and sustainability expertise.

A people business attached to a permitting queue. Growth tracks the volume of infrastructure and energy projects needing environmental review, and the constraint on scaling is licensed staff — which is exactly why the segment consolidates through acquisition rather than hiring.
