Urban heat mitigation subsidy policies
The Cool City Imperative: A Strategic Framework for Urban Heat Mitigation Subsidies Abstract: The 21st-century city is becoming an oven. The Urban Heat Island (UHI) effect—a phenomenon where urban areas experience significantly higher temperatures than their rural surroundings—is exacerbating the deadly impacts of climate change, turning metropolises into traps of hazardous heat. This thermal penalty has severe consequences: spiking energy demand, compromising public health, degrading environmental quality, and impairing economic productivity. In response, a suite of urban heat mitigation strategies, from reflective cool surfaces and green infrastructure to smart urban design, has emerged. However, widespread adoption is hindered by a classic market failure: the costs of mitigation are private and upfront, while the benefits are public, diffuse, and long-term. This article argues that strategically designed public subsidies are not a mere policy option but a fundamental urban gov...
