Whitepaper: Permeable Pavement and Urban Heat Island Mitigation by Porous Lane

The urban heat island (UHI) effect, characterised by higher urban temperatures relative to rural areas, poses severe challenges to urban health, liveability, and sustainability. Among the array of mitigation strategies, permeable pavement systems have emerged as a proven, effective, and multifaceted solution. This white paper synthesises global research and practical guidance to show how permeable pavements reduce surface and ambient temperatures, improve stormwater management, and deliver co-benefits for cities seeking resilience in a warming climate.
