Colombia once again stood out in environmental matters after four of its territories were certified as Tree Cities of the World in 2026. Medellin, Cali, Barranquilla, and Tocancipa received this international recognition granted by the Food and Agriculture Organization of the United Nations (FAO) and the Arbor Day Foundation, thanks to their policies for protecting urban trees, restoring green spaces, and promoting environmental education programs.
The distinction places these cities within a global network made up of 283 territories in 26 countries that have demonstrated a sustained commitment to urban sustainability. The program values actions aimed at strengthening the relationship between communities and nature within urban environments.
The announcement comes amid growing global attention toward resilient cities capable of facing challenges such as climate change, air pollution, and rising temperatures through green infrastructure and environmental conservation strategies.
What does it mean to be a Tree City of the World?
The Tree Cities of the World recognition honors municipalities and cities that meet international standards in urban forest management. To obtain this certification, local governments must demonstrate that they have an authority responsible for managing trees and green areas, specific protection regulations, updated species inventories, an annual budget dedicated to urban forestry, and ongoing educational activities.
Beyond the symbolic title, the certification represents a roadmap for building healthier cities. Urban trees play key roles such as carbon capture, temperature reduction, improved air quality, and protection of local biodiversity.
In addition, these green spaces have a social impact, as they promote recreation, mental well-being, and community ownership of public spaces. For this reason, more and more local governments are incorporating tree planting as a central part of their development plans.
Medellin, Cali, Barranquilla, and Tocancipa: examples of green management in Colombia
Among the distinguished Colombian cities, Medellin received the certification for the fourth time. The capital of Antioquia has promoted ecological corridors, recovery of green areas, and massive tree-planting campaigns. In recent years, it has also strengthened its urban greening strategy to reduce heat and improve sustainable mobility.
Cali also earned its fourth certification, supported by species monitoring programs, protection of urban watersheds, and conservation of its forests within the metropolitan area. The city has also promoted citizen campaigns for the care of parks and tree-covered spaces.
Barranquilla, meanwhile, reached six recognitions, consolidating itself as a leader on the Caribbean coast in urban forestry. In recent years, the city has transformed avenues, parks, and public spaces through landscaping projects that increase vegetation cover.
The case of Tocancipa also drew international attention. The municipality, located in the department of Cundinamarca, earned its third distinction, demonstrating that smaller localities can also lead successful sustainability processes when there is long-term environmental planning.
