The EU Delegation to Korea participated in the 2017 Seoul Car Free Day with its electric car. The EU's campaign for this year's car free day was to "stop idling" the car engines, as it is detrimental for the envrionment and health, especially that of children. The World Car Free Day started in the EU countries, but now it has come to Seoul. Every year there is the International Car Free Day, and during the week around the day, there are events to inform people about the harmful effects of car fumes. Many cities ban private vehicles from some of the busiest streets on the day. The 2017 Seoul Car Free Day was a rare chance for walkers in central SEoul to have free run of the streets that were closed for them.
