This report analyses the data collected by Erasmus + projects between 2014 and 2020 focalised on the education for environmental sustainability. The primary part of the study was searching the Erasmus + database and creating a list of 120 projects labelled as “good practices”. Starting from this list, 15 projects were chosen for the examination. The report summarises the results of the 15 case studies establishing and showing successful approaches in supporting the EU policies around environmental sustainability education.
