Treecorp is a start-up company that plants trees to help the planet, with the aim of bringing benefits to communities and ecosystems, focusing our actions on environmental and social sustainability. We plant trees to absorb CO2 and create natural parks to preserve different species of plants and trees.

We also support gender equality and are always looking for new challenges and opportunities to broaden our positive impact.

Treecorp means "corporation of trees": just as trees form corporations to collaborate in protecting themselves and maintaining biodiversity, Treecorp works in schools with a sustainability education project to directly teach children how to behave responsibly toward our planet.
