Lamai International School (LIS) on Koh Samui has embraced an Education for Sustainable Development (ESD) program within its curriculum. ESD fosters changes in knowledge, skills, values, and attitudes to promote a more sustainable and equitable society. It empowers students to make informed choices and take responsible actions in favor of environmental preservation, economic sustainability, social justice, and healthy lifestyles. The LIS ESD initiative aligns with the UN Agenda 2030 and its 17 Sustainable Development Goals, featuring a significant focus on Socio-Emotional Learning. Through this program, our students cultivate the knowledge, skills, attitudes, and values required to address challenges related to sustainable development. By adopting a holistic approach to Sustainable Development and involving parents and the local community, LIS is dedicated to nurturing responsible citizens committed to a better world and personal well-being.
