UBC tool maps urban tree sites with highest cooling potential

Researchers at the University of British Columbia, in partnership with municipal authorities, have released a new modeling tool that assists cities in addressing the health and environmental impacts of rising temperatures. The software uses climate and urban data to identify neighborhoods where planting additional trees would provide the greatest cooling benefits, allowing planners to prioritize locations that maximize shade, evapotranspiration, and heat‑mitigation effects.

The model incorporates local temperature projections, building density, and existing vegetation cover to calculate potential temperature reductions for each site. City officials can input budget constraints and maintenance considerations, enabling a cost‑effective allocation of resources. Early trials in several UBC‑partnered municipalities have already highlighted previously overlooked green corridors that could lower street‑level temperatures by several degrees during heatwaves.

By offering a data‑driven approach to tree‑planting, the tool aims to help cities meet climate adaptation goals while improving air quality and public health. Municipalities that adopt the model can target investments where they will yield the most immediate and measurable cooling, supporting broader efforts to create more resilient urban environments.
