Tree Cities of the World Sets New Record, Showcasing the Global Power of Trees

Representing 24 countries and six continents, these communities range from small towns of 1,500 residents to cities of 12 million, collectively speaking 37 languages and home to over 134 million people. 

Tree Cities of the World celebrates cities that prioritize urban forestry to enhance livability, sustainability, and climate resilience. The program, aligned with FAO’s Green Cities initiative, connects municipalities with global networks of urban forestry professionals, supporting canopy growth and community forest management. Recognition often translates into increased local funding and public support for trees — a critical resource for cities facing environmental and social challenges. 

“Trees bring people together,” said Sophie Plitt, program manager at the Arbor Day Foundation. “They transcend borders and language, infusing cities and neighborhoods with boundless value. They clean the air, cool our streets, and create spaces where life can flourish.” 

At its core, Tree Cities of the World is more than a recognition program; it’s a rapidly growing global movement. By upholding its five core standards, cities join a network of passionate organizers and tireless tree planters, transforming how communities value their urban forests. As the program continues to expand, it reinforces a simple yet profound idea: trees are a shared investment in a healthier, more resilient, and more connected future.
