Two different MOOCs have been created to explore and to teach the not-so-well-known problem of odour pollution and are available in English, Greek and Spanish. The first MOOC, addressed to the general public, offers the opportunity to understand some of the factors contributing to odour pollution and how it affects our lives. The second MOOC is specifically designed for formal and non-formal educators and provides a set of learning activities that they can use in their teaching context. Both MOOCs examine the impacts - environmental, social, health and economic- of odour pollution and what some of the available tools for tackling the problem are.
