What happened

The record, in order.

UNEP reported that Medellín's 30 green corridors, on 18 avenues and 12 waterways, received the 2019 Ashden award.

UNEP also reported the city's own statement that the corridors cool the local microclimate by up to 2 °C; independent verification was not found.

PreventionWeb (Reuters) reported in 2021 that the corridors pass through some poor neighborhoods and were cited as an example in the fight against heat.

El Colombiano reported in February 2014 that councillors said heavy structures on the Cinturón Verde slope in Comuna 8 conflicted with the protection of the green belt.
