After a summer marked by extreme heat, drought and devastating wildfires, the need to take positive action has never been clearer. Schools can play their part by joining hundreds of schools around the world for JUST ONE Tree Day on Friday 16th October 2026.
Completely free for schools to take part in, JUST ONE Tree Day provides everything needed to run a fun and engaging day of climate education, including curriculum-linked teaching resources and activities. Schools can take part with a non-uniform or ‘wear something green’ day, with pupils invited to donate just £1 to plant a tree in one of JUST ONE Tree’s reforestation projects across
Africa, Asia and South America — with one tree planted for every £1 raised. The annual event gives children and young people a simple, positive way to make a difference while learning about climate change, biodiversity and the importance of restoring our planet.
Since JUST ONE Tree Day launched in 2019, more than 250,000 children across 17 countries have taken part, collectively helping to plant over 475,000 trees and restore ecosystems around the world.
The event also comes as JUST ONE Tree celebrates a major milestone: the charity has now planted its 6 millionth tree since it was founded — a landmark achievement in its mission to restore the planet’s ecosystems.
With climate change increasingly affecting children’s lives, JUST ONE Tree Day also aims to help ease eco-anxiety through positive action, showing young people that they are not powerless in the face of the climate and biodiversity crises.
JUST ONE Tree founder Amanda Bronkhorst said: “Many children today are experiencing climate anxiety because they are seeing the reality of the climate crisis all around them. JUST ONE Tree Day gives children something positive they can do. It shows them that their individual actions matter and that, when we act together, we can create meaningful change.”
JUST ONE Tree is a British non-profit organisation and proud partner of the United Nations Decade on Ecosystem Restoration. Its restoration projects help restore vital ecosystems and wildlife habitats, capture carbon dioxide from the atmosphere and support local communities through sustainable livelihoods.
There is still time for schools to sign up for JUST ONE Tree Day on 16th October.
