In today's world, developing environmental consciousness in children is crucial to ensuring a sustainable future. Sweden is an example of a country that is committed to protecting the environment and sustainable development, which becomes apparent through its educational policies and practices. Sweden has a large number of organizations whose main goal is to encourage the environmental consciousness of children and educators, as well as parents, about important environmental issues. The Swedish preschool curriculum integrates ecology and sustainability as key aspects of education. Kindergarten programs focused on teaching children about recycling, energy conservation and understanding nature and its cycles. The importance of children's autonomy and active participation in decision-making on issues affecting the environment is particularly emphasized. Sweden is dedicated to education that promotes environmental, social and economic sustainability, with the goal of creating environmentally conscious and responsible future citizens. This approach allows children to develop a sense of responsibility and become active participants in the preservation of the environment. Researches show the importance of professional training for educators to better understand and apply all aspects of sustainability to their teachings. Case studies provide approaches that enable children to learn the importance of sustainability in a fun and engaging way. Also, it is important to recognize that education for sustainability is not only the responsibility of the educational system, but also of society. Research points to the need to change the approach in educational practice in order to integrate the values of sustainable development to all levels of education even more than it already is to assure a more sustainable future.
