Seoul's Weekly No Driving Day program is improving air quality, congestion and saving energy. Every year, two million cars stay off the road – decreasing traffic volume by 3.7%. CO2 vehicle emissions are being reduced by 10% - a total of 2 million tons of CO2, delivering annual savings of $50 million USD in fuel costs. The improved air quality is also improving the health of residents, saving the City millions annually. The program works because it is applied during weekdays, which encourages people to use alternate modes of transport to and from work.

What is it?

A voluntary program where people choose one day a week (Monday to Friday) as a no driving day. Participants are given incentives, which are provided by public organisations and private companies, such as discounted petrol, free parking and car washing, to use alternate modes of transport of the selected days. Participants are encouraged to take part as often as they can. Those participating just three times a year, for example, will have their incentives removed or diminished.

How does it work?

People wanting to take part in the scheme select a weekday that they will not drive. They register their chosen day on a website and receive an e-tag for the windscreen and sticker for the rear window. This enables the City to monitor usage through a RFID (Radio Frequency Identification), which verifies compliance and ensures that participants are registered and therefore eligible for the incentive scheme.

Incentives include: 

Public Organisations:

  • 5% Reduction in Auto Tax
  • 50% Discount on Congestion charge
  • 10~20% Discount on Public parking fees

Private Sector:

  • 1 to 6 cents/L Discount on Gasoline price
  • 10% Discount on Car maintenance cost
  • Free or Discount on Car washes

There are no real benchmarks set on the number of days participants are expected take part each year. However, if a participant only drove on the selected day three times a year, some of the incentives would be cancelled or stopped for that year.

Eligibility: Non-commercial vehicles carrying less than 10 passengers are eligible to take part in the scheme.

Time applied: 7am to 10pm on the selected day – excluding Saturdays, Sundays and Public holidays

CO2 emissions

1 million cars participating in the ‘No Driving Day’ program delivers a reduction of about 243,000 tons of CO2 emissions, a reduction rate of 9.3% and equivalent to about 6% of total CO2 emissions per year in Seoul and about 20% of CO2 emissions from the transport sector.

  • 3.7% decrease in traffic volume
  • 3% increase in operating speed
  • 50 m US$ annual savings in fuel costs
  • air quality improvement and clean city

Participants with e-tags – 653,000 (participation rate 30% of total eligible vehicles)

Next steps

The central Government is making efforts to spread such a program across the country. Since June 2006, all public institutions in Korea started adopting the similar system.

In July 2007, the weekly no-driving day program in Seoul will be unified to the electronic tag system, eliminating the requirements for paper stickers.


Recently, some satellite cities in Geonggi province have applied to participate in the program by sharing the electronic tag system in cooperation with Seoul city. Participants are also required to comply with the pre-selected no-driving days, which are then monitored by the RFID system.

The system is easy to apply to cities – it requires partnering with transport-related businesses to incentivise the community and setting up a monitoring system, through e-tags. Many existing e-tag systems can be expanded to include this type of monitoring.
