The concept of sustainable urban development has evolved significantly over the past decades, shifting from a purely environmental focus to a more integrated approach that encompasses economic, social, and ecological dimensions. Contemporary scholars argue that true sustainability in cities requires a systemic perspective, recognizing the interdependence of infrastructure, governance, and community well-being. For instance, investments in green transportation not only reduce carbon emissions but also improve public health and access to employment, thereby addressing social equity. However, critics caution that without robust regulatory frameworks, such initiatives may inadvertently lead to gentrification, displacing low-income residents. Therefore, effective urban policy must balance innovation with inclusive planning, ensuring that the benefits of sustainability are equitably distributed across all segments of society.
