In a series of measures to cut urban pollution, the French capital will be introducing free mass transit for children under 11.

According to Le Parisien, “2019 is going to be a historic year for Parisian families”. Beginning in September, all children under 11 will be offered free public transportation.

The paper says the measure will stay in effect over the next 20 years, at least.

The change will cost taxpayers EUR 15 million a year.

Public transit passes for teenagers aged 14-18 will be 50% off. Teenagers will also be offered free Vélib’—the Paris public bicycle-sharing system—passes.

In 2018, Paris made mass transit free for persons with disabilities.

The city also plans to ban all cars running on petrol and diesel from its central area by 2020.
