Whether you are working with a single site or a complex global portfolio of sites, we have the resources, tools and processes to execute time sensitive, cost effective and standardized due diligence services.

With access to over 4,500 environmental professionals through the Inogen Alliance and the use of a best-in-class web-based information management system, we can collect, evaluate, and report on environmental risks related to properties anywhere in the world with the level of accuracy and transparency required of sound business transactions. We focus on both the tangible and intangible risks to help you understand the complete picture of your transaction.

Our Due Diligence Services

Desktop Reviews

To screen the targets for known issues, data room reviews, review of commercially available databases, and review of publicly available information from regulators, agencies, or otherwise.

Site Visits

To review the site operations, conditions, infrastructure, interview personnel, and assess the potential for neighboring or regional issues.


With facility-level personnel as well as interviews with the c-suite team to ferret out less tangible issues, geared around specific topics (culture, management systems, organization, pending litigation, formerly owned properties, etc.).

Phase I/II Environmental Site Assessments (ESA)

More formal processes used to identify and/or characterize potential subsurface contamination risks (i.e., soil, groundwater, soil vapor).

Material Compliance Reviews (MCR)

Formal reviews of site conditions and operations to identify compliance risks that are material to the deal, associated with applicable environmental, health, and safety regulations.


Screening tools include product stewardship assessments, assessment of water resourcing risks, energy efficiency evaluations, sustainability programs (benchmarking), GHG/Climate Change screening assessments.

Financial Reviews

To evaluate reserves, operational budgets, and planned CAPEX for indications of known liabilities and/or discrepancies with expected expenditures.

Social and Cultural Risk Evaluations

To serve the needs of global financing institutions as well as corporate requirements for ESG standards, following IFC performance standards as well as EBRD performance requirements.

Integration Risk Assessments

To analyze due diligence with foresight to understand EHS challenges from a post-acquisition integration standpoint (merging management, systems, policies, procedures, and cultures).

Liability Identification, Quantification, and Risk Transfer

To identify and understand EHS downside risks, evaluate triggers, assess the likelihood of realizing the risks. Then we develop plans for managing the risks post-acquisition, and offer tools and solutions for mitigating exposures.

Cost Modeling and Probabilistic Liability Quantification

For situations involving significant uncertainties and unknowns forecasted as part of the risk analysis. Probabilistic modeling can provide a reasonable approach to risk quantification such that the risks can be incorporated into financial models at the deal table.

Transportation Safety and Compliance

Evaluate targets for fleet safety, vehicle maintenance records, driver training programs, and DOT compliance. We also have the capability to quickly benchmark a target against its peers for vehicle inspection rates (and associated violation rates), behavior analysis and safety improvement performance ratings, crash indicator scores, enforcement cases, fines imposed, and vehicle out-of-service rates.
