As urban centers account for over 70% of global CO? emissions and 78% of energy consumption, the imperative to transition toward sustainable smart cities has become critical. This article examines the transformative role of predictive analytics, artificial intelligence (AI), and advanced sensing technologies in addressing the challenges of resource management, environmental sustainability, and urban resilience. With over 700 global cities committed to net-zero emissions by 2050, AI-driven solutions such as smart grids, intelligent transportation systems, and digital twin technologies are redefining urban governance. Case studies from cities like Seattle, Tucson, and Las Vegas demonstrate measurable outcomes, including up to 30% reductions in traffic congestion, 10% declines in CO? emissions, and enhanced efficiency in water infrastructure spanning thousands of miles. By integrating real-time data analytics with machine learning, cities are transitioning from reactive to proactive management frameworks, enabling optimized energy distribution, waste reduction, and adaptive urban planning. This work synthesizes emerging trends in smart city technologies, emphasizing their capacity to align economic growth with ecological stewardship. The analysis underscores the necessity of scalable, interoperable systems to meet the demands of a rapidly urbanizing global population projected to reach 60% by 2030. By 2025, predictive analytics will serve as a cornerstone for achieving sustainability targets, fostering resilient urban ecosystems, and mitigating climate change impacts through data-driven innovation.
