According to the Decision No 1386/2013/EU of the European Parliament and of the Council of 20 November 2013 on a General Union Environment Action Programme to 2020 we should aim to "Living well, within the limits of our planet". Our project will foster to trigger students awareness and good attitudes towards living well but in the same time respect the earth, the nature and generally our whole environment developing a more sustainable way of school life. A discussion will be urged among students on how to reduce litter production and energy waste in our schools. Students will have to evaluate litter problem in their school and then form a plan on how to solve it. Following this, students will share their thoughts with the other schools and develop an action research. Eventually, we will start to implement our plan. A common date will be defined in which we will clean a dirty area outside of our schools. At the end, students will evaluate their experience!
