The whole school approach to Education for Sustainable Development (ESD) embraces a holistic and participatory educational philosophy that aims to enhance the potential of the school environment to function as an authentic and meaningful learning place. There is rich diversity in ways this approach plays out in different places, both within countries and globally. However, a common guiding principle is the integration of three lines of action: environmental management (“greening”) of the school, establishment of ongoing partnerships with the broader local community to address issues of social-environmental sustainability, and incorporation of sustainability in the curriculum. Hence, a whole school approach demands involvement of all parts of schools and stakeholders in the society to expose students to real sustainability issues. In this chapter, I describe how the idea of whole school approaches has developed in the literature by presenting different models and present a school organization model that can be used to guide implementation of ESD in a whole school approach. Aspects of school organization that facilitate implementation of ESD from a whole school approach are highlighted, with a focus on school leadership.
