摘要：The aim of the paper is to contribute to the research on education for environmental citizenship in a comparative perspective. The central concept of education is the complex issue of knowledge. In the present paper, different knowledge forms, knowledge use, and types of knowledge production in environmental education are analysed for two EU countries, France and Hungary, together with two candidate countries, Serbia and Turkey. We review the most important theories and publications, the research questions and the methods considered to be examples for our present work. The second part of the paper presents the case studies according to the theoretical priorities. Evidence-based papers on cases in different European countries illustrating and discussing the evaluation of the types of knowledge used in environmental education and sustainability projects, as well as analysing the power-related components of knowledge use are reviewed. In the final part, case studies are compared and conclusions are drawn.
