Per year around 480 billion Euro are spent on the public procurement in Germany. This market power can contribute to the conservation of biodiversity if e.g. biodiversity criteria are embedded in public tenders and thus it becomes the bidders’ responsibility to assign biodiversity-friendly agriculture, construction works and property management. The German Federal Agency for Nature Conservation recognized a research demand how to include the public protective good “biodiversity” as a legitimate criteria in public tenders as well as existing ecolabel standards. Main goal of this feasibility study is to prove if biodiversity can be considered in German public procurement and the construction sector. If so, specific applicable and practical action plans will be drafted.
