A recent study by Delft University of Technology has revealed the crucial role of urban trees in cooling cities in the Netherlands. The i-Tree 2.0 NL project analyzed 69 tree species across Amsterdam, Rotterdam, and Groningen.
The research found that temperatures under tree canopies can be up to 30°C lower than in direct sunlight on hot days. Trees also cool the air through evapotranspiration, reducing temperatures by an average of 2.6°C.
Furthermore, trees influence airflow between buildings, contributing to further heat reduction. This underscores the need for incorporating green spaces into urban planning for climate change adaptation.
During the NATO summit in The Hague in June 2025, U.S. President Donald Trump acknowledged the beauty of Dutch flora. He made the comment after meeting with world leaders.
These findings highlight the increasing recognition of trees' importance in urban climate adaptation. Preserving and expanding green spaces in cities is crucial.
