Advertising which targets children and promotes unhealthy food such as chips and ice cream will be banned throughout the Amsterdam metro system from January 1 next year.

The ban follows the city council’s alliance with the Stop Kindermarketing campaign, which aims to bring an end to the promotion of unhealthy food aimed at children.

The city has decided to start its campaign with a ban on advertising unhealthy food at its own and subsidized events, and at council-owned locations. This includes the city’s 58 metro stations, including those of the yet-to-be opened North/South service, officials said in a statement.

Figures from the city’s health board in 2015 show one in five Amsterdam children is overweight.
