A new approach to education has been proposed, called Education for Sustainable Development (ESD), with the goal of developing education in order to foster individuals who will contribute to the realization of a socially, economically, and environmentally more sustainable society. From the beginning of the 21st century, this has given rise to discussions and practices on related themes all over the world, including in Asia. While the environment surrounding education is markedly changing in Asian societies, with educational reforms actively pursued in many Asian countries and regions, their situations greatly differ depending on the context in which they find themselves. Today, departing from the conventional modes of teaching and learning that focus on the acquisition of an already systematized body of knowledge and skills, the field of education the world over is now shifting its focus to what is called key competencies, adopting and experimenting with new teaching and learning styles to develop abilities referred to as 21st-century skills. Based on these theoretical and conceptual discussions, a number of initiatives have been adopted as policies, school curricula, and educational practices in order to promote ESD in Asian countries. It is possible to divide Asian countries into three groups based on the place of ESD in their countries, as well as their degree of socioeconomic development and the popularization of school education: (a) countries that have accumulated experience in the practice of environmental education or development education; (b) countries that have been witnessing growing environmental consciousness and its rapid institutionalization in recent years, with varying degrees of implementation of environmental education; and (c) countries in which the elimination of poverty and inequality remains the most pressing issue and ESD is promoted in connection with development issues. Although the introduction of ESD is greatly affected by each country’s socioeconomic situation, it is important for all countries in Asia to promote equitable and sustainable education in order to realize a sustainable society. Thus, Asian countries need to form a social consensus to promote ESD, which requires the participation and responsibility of the whole of society.
