The article discusses the main events leading to education for sustainable development (EDS). It is based on the theoretical analysis of literature and documents from international conferences and on the achievements of the scientific team on environmental education (EE) in Bulgaria. The road to education for sustainable development started long back, passed through introduction into schools as the subject nature study and continued as organised activities of global institutions and educators. As the interaction of humanity with nature deepened and became more and more complex, humans reacted with increased emphasis on environmental education (EE). The international educational society at each successive stage of BE undertook competent rethinking of achievements and shortcomings and offered new recommendations for improvement. The history of EE, if critically studied and analysed, is a rich source of accomplishments, suggesting new ideas for further development.
