Extreme heat is increasingly pushing urban areas, infrastructure, and ecosystems beyond their limits, with cities being particularly vulnerable. Rising temperatures pose significant risks to public health, especially for vulnerable populations, and strain energy systems due to increased cooling demands. Without effective mitigation and adaptation strategies, the frequency and intensity of heatwaves are expected to rise, exacerbating climate-related challenges. UNEP's initiative aims to address these risks by promoting sustainable cooling solutions and enhancing urban resilience to protect communities and ecosystems.
