Cool Pavement in Los Angeles Reduces Urban Heat During Heatwaves
US · Published Aug 3, 2026
Los Angeles has been implementing a 'cool pavement' initiative since 2021, applying a solar-reflective coating to streets, parking lots, and basketball courts to combat the urban heat island effect.
This phenomenon causes cities to be 1–7°F (0.5–3.9°C) hotter than surrounding rural areas due to heat absorption by manmade structures.

Impact & Risks

The implementation of cool pavement in Los Angeles has shown promising results in reducing the urban heat island effect, which disproportionately affects densely populated areas with limited green spaces. By lowering ambient temperatures and moderating temperature fluctuations, the initiative could improve public health outcomes, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions. However, the long-term effectiveness and scalability of this solution remain to be fully understood, as further studies in other cities are needed to confirm its broader applicability.
