One More Tree Foundation is a non-profit organization founded by two friends to address climate change through practical environmental action. Its central ambition is to plant one million trees in Poland and Europe, while also supporting broader efforts to protect nature and improve local surroundings. The foundation works with individuals, businesses, local authorities, and communities to identify suitable planting locations and deliver projects that respond to local ecological needs.

Its activities include tree planting, pocket forests, flower meadows, urban greening, forest cleanups, and planting shrubs and flower bulbs. For businesses, it offers opportunities to take part in corporate tree-planting campaigns, employee volunteering, and other corporate social responsibility activities. The organization also provides ecological workshops and lectures to build environmental awareness among employees, students, and local residents.

Projects are designed to bring ecological, social, and aesthetic benefits, involve local communities, and support biodiversity through planting different tree species. As a non-profit, One More Tree Foundation directs the funds it raises toward environmental protection initiatives, helping create greener spaces intended to serve communities for years to come.
