Tree-Nation

You reforest the world
https://tree-nation.com

Tree-Nation is the largest reforestation platform enabling citizens and companies to plant trees around the world.

Tree-Nation’s mission is to reforest the world. The organisation offers people the possibility to select from over 300 different tree species which can be planted in 50 different reforestation projects located in 6 different continents. In every project, the species are carefully selected according to the specific benefits they bring for the environment and to the local population. Each tree planted on the Tree-Nation platform is assigned its own unique URL, which means the species, the location, the plantation project information and the CO2 compensation values can be tracked throughout the lifetime of the tree. Since its inception in 2006, more than 130,000 users and more than 2,200 companies have planted 5 million trees using its platform.
