As various measures are being developed to achieve the Sustainable Development Goals (SDGs) on global issues, the role of Education for Sustainable Development (ESD) is gaining attention. In May 2021, the UNESCO International Conference on ESD was held and the Berlin Declaration was issued to promote ESD for 2030. The importance of ESD has also been included in the Course of Study in Japan; thus, all schools, including UNESCO Associated Schools Project Network at primary and secondary education and ASPUnivNet at higher education, must focus on nurturing “creators” for a sustainable society. In response to these movements, Sophia University launched a project, known as the Sophia-ESD project, to pursue research on the educational practices, policies, and theoretical significance of ESD. The research activities consist of three dimensions: (1) practical ESD, (2) evaluation model, and (3) comparative analysis. The goal is to engage in theoretical and practical research on ESD to enable high-quality and competency-based learning competencies. At the same time, we seek to expand our ESD education and research network in collaboration with relevant organizations in Japan and overseas.
