A long-term campaign was launched in the ENO Programme in 2008. Our target is to plant 100 million trees by the end of 2017. 17 million trees have been planted by 2014The ENO Programme challenges all the children and youth and their schools or associations in the world to join this common effort. They are welcome to join ENO Tree Planting Days, for instance.

ENO schools plant trees during the school year. In addition, there are two special tree planting days. They are around 22 May and 21st of September. Both dates are UN theme days, first one for biodiversity and latter for peace..
