Sustainability by Education is an organization composed of students from different nationalities, studying in different countries of Europe and we all agree in one powerful statement: it is necessary to transmit the global environmental problematic we are facing to the mass population and the best way to achieve this is to share our knowledge in schools. We organize interactive workshops related to climate change, renewable energies and sustainability where the students are able to understand and apply in a practical way all the concepts explained. This workshop is mainly designed for schools, differently adapted for students who are from 9 to 18 years old. The duration of the talks can be from 2 hours to a whole day activity. Local associations (such as cultural centres or “boy scouts” groups) are also addressed with the workshops.
