The Council Regulation (EEC) No 2081/1992 "on the protection of geographical indications and designations of origin for agricultural products and foodstuffs" addresses two problems of food markets in the European Union. Producers are facing increasing competition and downward pressure on prices, while high, uniform quality and environmental standards lead to a certain "uniformity" of foodstuffs. As a result, products can hardly be distinguished from each other on the basis of objectively verifiable criteria. Therefore consumers are faced with the problem that clear and comprehensible product informations for their purchase decisions are difficult to obtain. To address these problems, by Regulation (EEC) No 2081/1992 a legal framework for food producers was created to protect products with a traditional reference to the origin region extensively as well as to strengthen regional economy and protecting consumers from being misled. In the present work, a conceptual framework, based on literature analysis, is created to investigate the effectiveness of a protected designation of origin in a case study on "Styrian Pumpkin Seed Oil PGI". For this purpose, a producer- as well as a consumer-survey were conducted. The present results show that the certification of a "protected geographical indication", in the case of pumpkin seed oil, is a suitable framework to meet the corresponding targets for the involved producers. Furthermore, it has been found that the criteria of protected designation of origin are perceived correctly by consumers, whereas the recognition of certification is very low. The success of the protected geographical indication in the present case is more affiliated to the specific implementation rather than the certification itself.
