||Mercantile Value Reduction: Accounting for Stigma on Contaminated Land in Germany
||16th Annual European Real Estate Society Conference in Stockholm, Sweden
||The clean-up and re-use of contaminated land is a risky endeavour for many reasons. The clean-up may be incomplete so that some pollution goes undetected. Some substances in the ground may be unknown to be pollutants at the time of the clean-up process but turn out to be such later on. Areas may be completely clean but yet suffer a depressed market value because of ‘stigma’, i.e. the psychological fear that some negative impact or remaining cost may appear even though a proper site clean-up had been conducted. The phenomenon of stigma on contaminated land has been widely debated in the United States but received little scholarly attention in Europe – despite the fact that accounting for stigma is a legally approved best practice of appraisal in European countries. This paper surveys the German approach for the accounting of stigma on contaminated land and proposes a risk scoring method of accounting based on a survey among German appraisers and a study of sales practices of the Brandenburgische Boden GmbH – an East German property conversion company in charge of revitalising 22000 ha of lands formerly used by the Russian army in Germany.
