With growing populations – predominantly in the tropics – and rapid urbanization, the impact of global warming is felt most acutely in cities. Research shows that the world’s cities are heating up at twice the global average rate due to the urban heat island effect – a phenomenon where urban areas experience higher temperatures than outlying areas due to a combination of diminishing green cover, heat gain and thermal properties of the materials commonly used in urban surfaces, as well as waste heat from human activities (such as industrial processes, transport and air conditioning).
This guide by UNEP offers planners an encyclopedia of proven options to help cool cities sustainably, providing improved health and productivity, economic benefits, and reduced power usage and emissions. The guide’s 80 supporting case studies and examples demonstrate the effectiveness of the strategies outlined and can help cities find an approach best suited to their unique contexts.
