Values and beliefs lie at the heart of any organisational culture, expressed through artefacts and symbols, but especially though the behaviour of the people there. Key principles for sustainable cultures include recognising individual contributions, using fewer consumable resources, diversity and community working. Examples are given of school initiatives which show commitment to conservation. The role of leaders is critical in developing such cultures and leaders′ ability to think strategically and ensure personal goals cohere with school ones are central. Such leaders tend to be reflective, modest, unselfish, fair and effective at managing change. Change at local level is the key to larger scale reform at national educational system levels, and can address economic and political issues. Further examples stress schools′ community involvements and underline the conclusion that the greatest inspiration for young people in developing sustainable cultures is the actions and behaviour of leaders and other relevant adults.
