This research study documents several national initiatives, such as Enviroschools, New Zealand; Green School Award, Sweden; Green Schools, China; and the international programs of FEE Eco-schools and ENSI Eco schools. It is our intention to review these experiences of wholeschool approaches to sustainability in order to address the following questions: What does a sustainable school look like? Is there a formula for 'how' to run an effective and wide-reaching whole-school sustainability program? Is there evidence of effective methods to engage the community in these endeavours? What are the critical success components of whole-school sustainability programs?
