As part of UWE Bristol’s commitment to the city of Bristol in the UK being designated European Green Capital in 2015, they developed a massive open online course (MOOC) called Our Green City. This course was developed by 14 academic from across the university, in collaboration with 24 external organisations involved in the Bristol Green Capital Partnership and many students. The course was not only taken by the staff and students at the university, but learners from 71 countries. It explores how to drive public engagement in any green city with a number of presentations, quizzes and community-led discussions exploring challenges in the area of food, nature, resources, transport, leadership and energy.
