The concept of 'sustainable urbanism' has evolved significantly over the past decade, moving beyond mere environmental concerns to encompass social and economic dimensions. While early proponents focused primarily on reducing carbon footprints through green architecture and renewable energy, contemporary scholars argue that true sustainability requires a holistic approach. This includes fostering community resilience, ensuring affordable housing, and promoting equitable access to public spaces. However, critics contend that many so-called sustainable developments often lead to gentrification, displacing low-income residents and undermining the very social fabric they claim to strengthen. Thus, the challenge lies not in technological innovation alone, but in reconciling ecological goals with social justice. A recent study of European cities found that projects integrating participatory planning processes were more likely to achieve long-term sustainability outcomes, suggesting that governance structures play a pivotal role. Consequently, sustainable urbanism should be understood as a socio-political project as much as an environmental one.
