What is ENO?

A global school and community network
for sustainable development


Climate change

Climate change has been the regular topic in ENO since the beginning in 2000.
Tree planting has been the most visible activity since 2004.


Rating the environment

We use Envirate in ENO, a mobile app to rate environment with our three senses: look, hear and breathe. Envirate weeks or days are being organised globally during the year.



Recycling campaigns will be organised during the school year.
Schools post their photos and videos of their projects  in ENO Facebook events.


Creative ENO ART

ENO is supporting children’s art as the way of expressing their creativity and raising sustainable awareness. Special contests will be orgainsed during the year. For all the creative work we use recycled materials.
