What is ENO?

ENO is a global network of schools and communities for sustainable development.


Climate change

We have addressed climate change for nearly 20 years. Over 30 million trees have been planted thanks to our global tree planting campaigns.


Rating the environment

Look, hear and breathe. We use Envirate, a mobile app to rate the environment. Join us in Envirate events throughout the year!



We organise recycling campaigns during the school year. Schools post photos and videos of their projects on ENO Facebook.


Creative ENO ART

We believe in art as a way of expressing creativity and raising sustainable awareness. Contests on selected themes are organised during the year. We use recycled materials for all creative work.
