The 15-minute city: Urban planning and design efforts toward creating sustainable neighborhoods

The purpose of this study is to explore the 15-minute city concept's underlying principles, sustainability contributions, and implementation challenges. We show that it relies on the seven basic principles of human-scale urban design, density, diversity, flexibility, proximity, digitalization, and connectivity. These principles can contribute to social, economic, and environmental sustainability in various ways. However, the 15-minute city can also been criticized for being physically deterministic, failing to take into account the needs of different social groups, biodiversity, energy-efficiency, clean energies, and culture and heritage.
