Environmental Due Diligence

Environmental Due Diligence

Environmental due diligence is one of the core competencies of Envi Experts.

Corporate transactions involve performance-relevant environmental risks. Success and security of the environmental due diligence, the diligent investigation of environmental liability and cost risks, are founded in a holistic testing system.
Our risk cost approach provides monetary results. Our holistic, process-oriented procedure ensures you a complete picture of the target. As a result our work technique makes all important economic, technical and environmental-administrative interfaces transparent.
Regardless of whether the targets are individual production companies, companies with branches or real estate, our environmental-oriented assessments provide a clear picture of risks, pragmatic action plans and a reliable implementation support.
EDD is only as good as its auditing structure. This reflects experience and professionalism. Envi Experts‘auditing structure makes all important technical, environment-administrative and economic environmental interfaces transparent. Over 20 years of experience have allowed us to develop an auditing framework that provides our customers the certainty that a successful transaction requires.

The structured audit of a target consists of Phase I and Phase II.


Typical topics of the Phase-I-investigation are e.g.:

  • Legal planning risks that endanger or limit utilization of the object,
  • technical environmental deficiencies that could trigger operational reliability risks, breach of obligations or official intervention,
  • pollutant contaminations on the premise and in the buildings and/or the indoor air that require remediation or restriction of constructional changes or
  • natural hazards like e.g. flooding that could endanger the existence due to the possible lack of insurance coverage.


If risks with need of technical testing were determined in Phase I, then an environmental investigation follows, Phase II. Depending on the requirement these technical investigations include soil-, groundwater- and building pollutant investigations or metrological system testing.
However, not only the risks are paramount for us, but also the opportunities. We don’t want to be a deal breaker, but rather show fair options that allow the investors an undisturbed post merger phase. At the same time, a seller can utilize the opportunity of the so-called vendor due diligence to identify risks early and with targeted measures to achieve a sale without undesired price reductions.
Our branch experience and our interdisciplinary cooperation in particular with the due diligence teams of the participating law firms and auditing companies ensure the realization of reliable contract documents. At the same time our monetarized results allow a clear economic risk assessment.

Special area of auditing: Product risks

Our extraordinary knowledge of material product risks and recycling management requirements for products is of particular importance. Supply chain- and pollutant risks could devalue the product, damage the company image and ruin the economic success of the target object.
