As urbanization accelerates globally, concerns about air pollution have grown, impacting metropolises' quality of life. Hanoi - the capital of Vietnam - is among these cities, having faced deteriorating air quality due to industrialization, vehicular emissions, and the urban heat island (UHI) effect. While numerous papers address air pollution in Hanoi and strategies adopted globally, a gap exists in deliberating on the alignment of such strategies with Hanoi's context. This paper aims to bridge this gap by investigating Hanoi's air pollution, correlating it with strategies used elsewhere, and proposing tailored solutions. Focusing on urban greening, low-emission zones, and improved waste management practices, this study explores flexible approaches for mitigating air pollution. Considering these strategies within Hanoi's context is essential for evaluating their potential benefits in Vietnam's capital. By linking global strategies to Hanoi's specifics, this research aims to develop localized air pollution solutions, drive sustainable city development, and contribute to existing knowledge. Collaboration among stakeholders is essential for successful and comprehensive implementation, which will result in improved urban air quality for Hanoi residents.
