Urban heat islands, where cities are warmer than rural areas, exacerbate heatwaves. In 2024, 60% of global cities implemented mitigation strategies, reducing temperatures by 3°C on average. Green roofs, covering 20% of urban buildings, cut cooling costs by 15%. However, installation costs of $200 per square meter deter widespread adoption. A 2023 study found that 70% of residents in mitigated cities reported better health. Reflective pavements reduce heat by 10%, but 25% of projects face maintenance issues. Tokyo leads with 30% of its buildings using green roofs. Critics argue that mitigation diverts funds from housing, while supporters emphasize climate resilience. Low-income areas, with 40% less green space, benefit least. Public participation is low, with 65% of residents unaware of initiatives. Funding relies on public-private partnerships, with 50% of projects privately financed. Regulatory frameworks vary, slowing progress in some regions.
