A sustainability strategy needs to consider – from all the SDG areas – what the school can and should deliver for its key stakeholders: students, parents, communities, local environments and supplier partners (e.g. food providers, uniform outfitters, transportation services). Private businesses often carry out a ‘materiality’ exercise to assess and evaluate where they have the greatest responsibility to deliver change. Through this, they assess and prioritise the issues which are most important both in the eyes of their stakeholders and for business longevity. Some examples of key potential issues for schools could include student health and wellbeing, reducing food waste, improving energy and water efficiency, reviewing supplier partnerships for ethical and sustainable practices and educating students on production practices.
