Since the 1970s, the understanding of cultural heritage (CH) has expanded from a focus on monumental conservation to a systemic, socially constructed concept shaped by communities and dynamic values. While recognized as a resource for sustainable development, CH remains marginal in global policy agendas, notably in the UN’s 2030 Agenda. This paper explores how the Historic Urban Landscape (HUL) approach and broader heritage systems can function as enablers of sustainable urban development, moving beyond heritage-as-object to heritage-as-process. It synthesizes conceptual advances, policy frameworks, and empirical cases—such as Capitals of Culture programs, adaptive reuse initiatives, and circular economy models—to analyze how heritage systems contribute to environmental, social, and economic sustainability. Drawing on a value-based and people-centered framework, the paper identifies key principles, models, and success factors for integrating CH into urban planning. Case studies from Europe and Asia illustrate the potential of heritage to foster inclusive governance, community resilience, and innovation, while also exposing challenges such as institutional fragmentation, gentrification, and policy–practice gaps. The findings highlight the need for holistic, cross-sectoral, and participatory strategies to embed CH meaningfully in urban transformation processes, offering concrete insights for advancing heritage-led sustainable development through the lens of systems thinking.
