National and international guests and experts will learn about one of the most representative initiatives in Medellín’s urban transformation: the green infrastructure strategy that integrates mobility, ecological connectivity, and landscape through tree planting, landscaping, and the restoration of permeable surfaces along the city’s roads and streams. This is how the capital of Antioquia is positioning itself in climate action and sustainability with its green corridors, and it will demonstrate this during Climate Week Biodiversity 2026, from September 28 to October 10.
On one hand, the Secretariat of the Environment is leading 29 “blue corridors”—that is, those associated with the restoration of streams. Between 2016 and 2020, 18 of these were implemented, covering an area of more than 733,000 square meters, while between 2024 and 2026, the remaining 11 corridors were added, covering more than 340,000 square meters. For its part, the Secretariat of Physical Infrastructure reports 27 green corridors, which are associated with road networks: 18 between 2016 and 2020, covering more than 77,000 square meters, and 9 between 2024 and 2026, covering more than 23,000 square meters.
Collectively, the city has a network of 56 corridors, covering a total area of more than 1,300,000 square meters, which have helped reduce surface temperatures, improve air quality, strengthen urban biodiversity, and restore ecosystem services in various locations. Investment in this strategy exceeds $200,000 million, financed primarily with the District’s own resources.
The network of green corridors, along with the capabilities, talent, and partnerships that Medellín has built in recent years, underpin its selection as the host city for this year’s Climate Week. The city has established itself as a Latin American leader in urban innovation, territorial transformation, and connectivity, with the ability to bring together diverse stakeholders to build collective climate solutions.
“For the first time, Climate Week is coming to Medellín and Latin America, and this is no coincidence. Today, the city has 56 green corridors that have already transformed more than 20 kilometers of concrete into green spaces, contributing to cleaner air and a city better equipped to face climate change,” said Jaime Andrés Naranjo Medina, Secretary of Physical Infrastructure.
The public can view the schedule and register for the various events through the official website, subject to available capacity. Admission is free with prior registration here and here.
The event is organized by the Medellín Mayor’s Office, in partnership with Impact Hub Medellín, Fundación Socya, the Climate Week Network, and ACI Medellín.
