Challenge / Goal

Every day in Vitoria-Gasteiz, over 40,000 people commute to work in the city's industrial estates. Most of these 40,000 trips are by car alone, generating significant emissions. Reducing the thousands of daily journeys from the city centre to industrial estates by commuters promises to have meaningful positive impact on both environment and society. The city seeks to do so in a way that can rationalise the use of cars for commuting without “criminalising” drivers through a promotion of shared mobility. The expected outcome is to change the habits of the people who live in Vitoria-Gasteiz while at the same time reducing the carbon footprint of the city.


To address this challenge, French startup Karos Mobility is optimising commuting with a pilot of their app in the city, matching drivers with passengers headed in the same direction with the aim of reducing the number of cars on the road each day. This allows commuters to maximise their trips, and even financially incentivises drivers to share their route with others. The way it works is that drivers set their route in the app and wait for other users to sign up, with each journey netting the driver at least €1.50 per passenger. With the employment of artificial intelligence and geolocation, the app matches drivers with the best possible passengers for their route.

Karos Mobility’s app delivers a host of benefits for users, and the cities they live in, by cutting unnecessary travel expenses and reducing commuters’ environmental footprint. The startup already boasts over one million users in Europe who use the app to carpool to and from work, providing successful examples to further enhance the implementation in Vitoria-Gasteiz. Beyond the positive environmental impacts of shared mobility, the Karos Mobility network is expected to deliver meaningful social and economic benefits by increasing social cohesion and connections through ride sharing. Finally, the financial benefits to users are also intended to be signficant, providing individual cost savings on daily commuting.

Citizen participation

Karos Mobility is actively engaging with users in the pilot, and these users are seen as fundamental because they are the ones who will help the app grow by word of mouth and who will advocate its benefits.
