<p>Eco-city policy is one of the cornerstones of sustainable urban development strategies, integrating climate policy objectives with social and economic considerations. In recent years, numerous eco-city projects worldwide have emphasised green construction, renewable energy deployment, efficient water management, and sustainable lifestyles. But their role in promoting economic resilience and mitigating the socio-economic impacts of climate variability remains underexplored. Using the Sino-Singapore Eco-city in Tianjin, China, as a case, this study examines how climate variability is associated with property prices in eco-city and non-eco-city areas. The findings disclose that eco-city enhances economic resilience, stabilising local real estate markets through the integration of green development goals. However, limitations in industrial diversity, constrained economic scale, and concerns over social equity underscore the need to refine eco-city policies–ensuring not only environmental sustainability, but also economic inclusiveness and social justice. By bridging climate policy and energy justice, this research offers valuable insights into promoting equitable and resilient urban transitions under climate stress.</p>
