Overview

Environmental Due Diligence & Assessment covers the environmental investigations performed in real-estate and corporate transactions — Phase I and Phase II Environmental Site Assessments (ESAs), contamination assessment, and regulatory due diligence that identify environmental risks and liabilities before a deal closes. It serves buyers, lenders, and investors protecting against environmental liability.

Demand is driven by transaction activity (every commercial property purchase and many financings require a Phase I ESA), regulatory requirements, and heightened concern over emerging contaminants (PFAS). It is a fragmented, specialized segment overlapping environmental consulting (profiled under Environmental & Waste Services), with recurring, transaction-linked demand and consolidation around environmental-services platforms.
