ETwinning help us to introduce a European educational perspective, approaching schools from different countries. "A Greener Education" is a project aimed at turning educational centres into more sustainable spaces where environmentally friendly practices are a routine and the students are aware of the climate change. All this through closing Science, Technology, Engineering and Mathematics (STEM) education to the students. This project is based on common needs for all educational centres to improve a better use of resources. We need to encourage innovation and motivation, foreign language learning and bilingual teaching methodology, respect and environmental harmony and encouragement of STEM education.
