ENO Tree planting days

Fight against climate change by planting trees! Schools and communities have planted trees with ENO over 20 years. Over 30 million trees have been planted thanks to our global tree planting campaigns.

ENO Green Cities

ENO Green Cities Network was launched in March 2012. It’s a different approach on sustainable city networks as it’s based on educational co-operation between schools and city administration, in a concrete way.

Climate Action

Climate change is one of the most urgent and biggest problems. We all have to do our part to reduce the effect of climate change. ENO has many operations to act!

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.
