NEW: REGISTRATION OPEN

EARLY BEE2027

10'000 people leave their car parked for 31 days. We recently reached that goal — much faster than expected.

In the canton of Ticino, registration is open for the first time. And that's just the beginning: we're working on having even more places in 2027 — and as an Early Bee, you'll be the first to know what's next.

4 GOOD REASONS FOR Heart
31DAYS

Planet

GOOD FOR THE ENVIRONMENT

Almost half of all households still own a combustion-engine car today. The transport sector is responsible for a large share of CO2 emissions. By going without, you actively contribute to climate protection!

Movement

MORE EXERCISE & AN ACTIVE EVERYDAY LIFE

Step out of your comfort zone and into a new mobility experience: getting from A to B more mindfully in everyday life while moving more in the fresh air – that's already two good reasons to join.

Discover

DISCOVER SOMETHING NEW

Experience complete freedom without your own car? Just give it a try! 31DAYS lets you test alternative mobility with no strings attached.

Money

GOOD FOR YOUR WALLET

Smart people take the train. Getting around without a car can save you a lot of money. Comparing it with alternative ways of getting around is worth it! According to official calculations, owning a car easily costs CHF 7'000* a year on average.

Do the maths yourself!

What does
your car cost?

A car costs more than you think. Calculations show that the average cost per kilometre is CHF 0.76 for every kilometre driven.

Es war ein großartiges Erlebnis. Wir als Familie hatten viel Spaß.

Die 31days Challenge war eine tolle Erfahrung. Es ist wunderbar mit dem ÖV zu fahren, oder besser gesagt, gefahren zu werden. Ein Genuss, wenn man außerhalb der Stoßzeiten unterwegs ist. Beeindruckend war für mich, dass trotz knapper Umsteigezeiten alles bestens funktioniert. Weitere positive Erfahrung: Viel Zeit zum Podcast hören und Dinge zu durchdenken, recherchieren und vorzubereiten. Ein GA lohnt sich zwar noch nicht für mich, aber ich werde sicher mehr mit ÖV unterwegs sein. Cool ist beim GA auf jeden Fall, dass man nichts machen muss, außer ein- und auszusteigen. Auch mal irgendwo zwischendrin. Vielen Dank für die Erfahrung

So cool! Einmal einen Monat lang einfach gratis losfahren, viel Neues entdecken und dabei die eigene Mobilität überdenken.

Meine Erfahrungen waren sehr gut. Das ganze war sehr Niederschwellig, einfach erklärt und unkompliziert. Das einzige etwas aufwändige und nervige waren die Fotos mit der Kennzeichennummer und Code von der App die man zusammen mit sich selber fotografieren musste. Im grossen und ganzen aber eine wundervolle Erfahrung so das ich mir danach direkt ein GA geholt habe und dies verlängert :)
