Do you want to help create a healthier, fairer, more environmentally sustainable society? Do you want to empower children and young people to do the same? Do you want to make your school more climate-friendly? If so, this guide is for you! The guidelines and examples are based on a survey looking at climate action projects at 55 schools in 12 countries. All schools in the survey are part of UNESCO’s Associated Schools Project Network (ASPnet). In addition, this guide draws on examples and research published in peer-reviewed journals, books, national and international guidelines and frameworks and programme websites.
