Recharging also requires a non-contact recharging facility to be installed at the station (such a recharging system is running in other Korean cities such as Jeju, Suwon and Pohang). The introduction of compressed natural gas buses is another example of low-pollution transport policy in Sejong. The central government provided a subsidy to Sejong to help the city adopt CNG buses. Sejong’s bus network includes 72 routes, served by 130 buses, among which 24 are BRT types.
