An environmental due diligence audit is a systematic survey of sites/buildings or possible investments on potential risks coming from soil and groundwater contamination or building contaminants e.g. asbestos & Co. On the basis of this inventory, known as "Phase I", a decision is made as to whether further technical investigations need to be initiated and carried out, if necessary.
An environmental due diligence audit can be valuable beyond any merger or acquisition interests, e.g. if a company would like to know the current status of a site. For sites with a long changing history this can be crucial.
The reports are also available in English on request.
