The objective of this Toolkit is to inspire, encourage and support universities to develop and implement their own transformative strategies for establishing green, resource-efficient and low carbon campuses. It will provide an opportunity to build stakeholder capacity to deliver systemic, institution-wide integration of sustainability principles into all aspects of university business. This initiative is intended to improve the sustainability performance of universities globally and to provide support to other stakeholders embarking on their own sustainability journeys. Further, it will enhance the practical relevance of universities to sustainable development and by extension, the new paradigm of the “green economy”. In short, the aim is to encourage and promote the contribution of universities to the overall sustainability of the planet. We cannot have a sustainable world where universities promote unsustainable – conversely, the sustainable university can help catalyse a more sustainable world.
