Background and Objective

Once devastated by war, Incheon has transformed into the Republic of Korea’s second-largest economic hub, anchored by its port and international airport. With rapid expansion and industrialization, the city now faces coastal vulnerability and inequality between new and old districts. Its 2045 Carbon-Neutral City Vision integrates environmental, economic and social priorities to achieve net-zero emissions while revitalizing urban areas. The core objectives include advancing low-carbon industries, strengthening disaster resilience, and promoting inclusive housing and mobility systems. Incheon’s 2040 Urban Master Plan institutionalizes these goals, ensuring that carbon neutrality, ecological restoration and equitable development drive the city’s sustainable transformation.

Actions and Implementation

Incheon advances its sustainability vision through strategic, results-oriented initiatives. The One Dollar Housing project provides ultra-affordable rental homes for newlyweds and young families, easing demographic pressures and improving social equity. The Intelligent Transport System integrates AI and real-time monitoring to improve safety, reducing traffic fatalities and emergency response times. The city’s hydrogen economy strategy featuring over 2,300 hydrogen vehicles and the world’s largest liquefied hydrogen plant anchors its industrial transition toward clean energy. Meanwhile, the Stream Restoration Project engages citizens and businesses in rehabilitating five major waterways, institutionalizing ecological stewardship through legislation and participatory partnerships that reinforce long-term environmental recovery.

Outcomes and Impacts

Incheon’s integrated approach has yielded tangible improvements across social, environmental and economic dimensions. The One Dollar Housing initiative reduced housing costs by 96 per cent for participants, supporting family formation and stabilizing population trends. ITS deployment cut traffic deaths by 27.6 per cent and boosted emergency response reliability to 94 per cent. Stream restoration improved water quality and generated USD 42 million in annual ecological value. The hydrogen cluster has driven clean industrial growth and created new jobs, while emissions show a steady decline. Collectively, these results reflect Incheon’s success in translating sustainability principles into equitable, measurable urban transformation.

Sustainability and Scalability

Through its 2040 Urban Master Plan and 2045 Carbon-Neutral Vision, Incheon embeds sustainability into long-term governance and cross-sector planning.

Its policies integrate smart transport, renewable energy and inclusive housing into one cohesive framework. Public-private partnerships, citizen participation, and continuous monitoring ensure accountability and adaptability. The model’s scalability lies in its legislative integration, enabling replication in other cities facing industrial transition or climate risk. By combining fiscal innovation, stakeholder engagement and data-driven management, Incheon demonstrates a replicable pathway to sustainable urban evolution.

Gender and Social Inclusivity

Incheon’s policies promote inclusivity through equitable housing, safe mobility and participatory governance. The One Dollar Housing project directly supports young couples and families, reducing financial barriers to marriage and childrearing. Transport upgrades prioritize vulnerable users children, seniors and people with disabilities through smart crossings and pedestrian-friendly design.
