Making liveable smart cities a reality

By improving the quality of life for South Koreans with state-of-the-art technology, Sejong City hopes to attract 500,000 residents by 2030.

Smart cities are transforming our understanding of urban infrastructure. Sejong City sought to establish itself as a global pioneer for other smart cities driven by state-of-the-art technologies, including Big Data, AI and Internet of Things (IoT).

The Challenge

Rebalancing South Korea's urban influx

To address Seoul's air pollution and overcrowding, government officials recognized the need for a radical solution to mitigate an increasingly unsustainable influx of people.

Their goal was to create a brand-new city to act as the country's administrative centre. In 2011, work began on building Sejong City. In line with the UN Sustainable Development Goal 11, 'Sustainable Cities and Communities', Sejong has since received 'smart city' certification.

The Solution

A world-leading smart city

In 2018, Sejong piloted a project for a new international standard for smart cities - an opportunity to show how sustainable innovation could transform urban living.

The BSI Smart Cities and Communities Kitemark is based on guidance around sustainable development and resilience of communities (ISO 37102). It was created following a five-year process of research and engagement with city leaders and aims to change the way that cities operate.

These benefits include improved reputation, protecting vital services for society, technological improvements, and attracting new residents.
