In this scholarly review we critically discuss the last 30 years of research on pluralism in environmental and sustainability education (ESE). Pluralism has been a focal point for a vast amount of theoretical and empirical studies in the research field. Since the journal "Environmental Education Research" (EER) was established, 158 articles have been published that to some extend refer to pluralism or pluralistic ESE. In this review we analyse the state-of-the-art of pluralism in relation to current societal changes and challenges. By placing three decades of research on pluralism in relation to key challenges that face democratic society and education, we outline prospects for future research and discuss what role pluralism can, and should, take in ESE research.
