A city that is just 24 minutes long

The city of the Little Mermaid and of the Tivoli Gardens, the world's second most ancient amusement park.

Its urban area sees 1,300,000 Danish people move around with 750 thousand bikes, greatly exceeding the number of cars: A remarkable achievement for a capital ranked among Europe’s greenest, now aligned with the national climate goal of becoming carbon neutral by 2050.

In October 2022, the reduction had reached 80%, which is already a good landmark, also thanks to Cityringen (one of the fundamental projects of the CPH Climate Plan 2025), the Line 3 of Copenhagen's Metro, which greatly contributed to this result. Built from 2011 to 2019, it includes a 43-km long circular route, 17 underground stations (approximately 30 metres underground) and two 15.5-km long tunnels.

Excavations took place mainly in limestone rock and glacial soils, in a densely populated urban centre, rich in historic buildings, including the Magasin du Nord (excavations were carried out up to 1.5 metres from its foundations). Numerous archaeological finds were discovered (some up to a thousand years old) during works. They were handed to Copenhagen's Museum. These include: ceramics, texture, foundations of ancient buildings and even bulwarks of an old port, making this the largest archaeological excavation in Northern Europe.  

With Cityringen completed, 85% of residents lives at a maximum of 600 metres (10 minutes by foot) from a metro station or a railway station. Travelling along the entire line only takes 24 minutes, at an average of 40km/h. Up to 72 million passengers will be able to travel on it every year. Copenhagen, with its 4 metro lines has now become the «15 minutes city»: just fifteen minutes of intermodal mobility for one's main daily travel needs are now required. And, obviously, bikes can be brought on board the metro.
