The Sustainable Development Goals (SDGs) as an ambitious and universal agenda to transform our world have issued the world a bold challenge: Provide all children with quality early childhood development, care, and preprimary education by 2030 (United Nations [UN], 2015). As a key instrument to achieve the SDGs, education for sustainable development (ESD) "empowers learners to take informed decisions and responsible actions for environmental integrity, economic viability and a just society for present and future generations" (United Nations Educational, Scientific and Cultural Organization [UNESCO], 2017, p. 7). International recognition of ESD as a key enabler for sustainability has been growing steadily and expanding to different stakeholders, which encourages early childhood education (ECE) to be more active in the transformative process (Engdahl, 2015; United Nations International Children's Emergency Fund, 2019; World Organization for Early Childhood Education [OMEP], 2017). ECE has all the possibilities in the world to lead children into interest, knowledge, and values that will give support for a more sustainable life and world, since children by nature are open-minded and curious toward the world around them
