This chapter explores the state of Early Childhood Education for Sustainability (ECEfS) in Taiwan. While Taiwan's government has taken steps to align national goals with sustainable development through initiatives like the National Sustainable Development Commission and the ‘Sustainable Development Goals Education Handbook,’ there is limited focus on integrating sustainability into early childhood education specifically. School resources and initiatives like school sustainability websites, the Green School Network, and Sustainable Campus Global Information Network exist, but direct references to early childhood education remain scarce. Potential connections are identified between the current early childhood curriculum and sustainability concepts, suggesting areas for alignment. Research and practice in Taiwan around sustainability education involves both bottom-up efforts and top-down government initiatives, but there is a significant lack of research focused at the early childhood level. Most sustainability education studies concentrate on primary school and above. Recent national competitions featuring the SDGs for early childhood curricula signal a potential shift, but challenges remain. These include the inadequate integration of sustainability in early childhood education practices, limited emphasis on sustainability in preschool teacher training, and a fragmented policy and research approach to ECEfS. Overcoming these obstacles will be key to advancing ECEfS in Taiwan.
