As cities around the world brace for extreme temperatures and waves of unrelenting heat, urban greening is one of the best solutions for leaders to combat this reality.

Trees cool the air through evapotranspiration, filter pollutants and absorb stormwater, and enhance biodiversity in urban spaces.
