This study aimed to investigate research articles that relate to education for sustainability, primarily in early childhood, in order to describe to what extent a holistic perspective on education for sustainability has been applied, and how the social dimension is conceptualized. The review comprised research articles in Nordic Journals of Education, International Journals of Early Childhood Education, and International Journals of Education/Environmental/Sustainability education. The findings disclosed that researchers within the field of education for sustainability acknowledged, to a large extent, environmental, economic, and social aspects, and thus applied a holistic perspective. This review shows, however, that even if the social dimension were conceptualized as strongly related to topics such as social justice, citizenship, and the building of stable societies, few articles have investigated diversity, multicultural perspectives, or migrant children's situations in the context of early childhood education for sustainability. This review discloses that the concept of belonging is rarely used in connection to migrants and refugees in research on early childhood education for sustainability. A further argument encourages the inclusion of these aspects in further research which claims social sustainability.
