Frequently asked questions

Answers to the most important questions regarding implementation, cost structure, data protection and impact.
How can we encourage our employees to start carpooling?

Employers can encourage participation by communicating the service internally, offering incentives, and integrating it into their broader mobility policy. Karos supports you with a communication toolkit and guidance to help drive adoption among employees.

Does carpooling work for industrial zones with several employers?

Karos works well for industrial zones and business parks where several employers share the same area. By pooling commuters across companies, the network reaches the critical mass needed for reliable matching, even when a single company alone would have too few participants.

Can Karos support our CSR and sustainability reporting?

Yes. Carpooling contributes directly to lowering commute-related emissions, which can feed into your CSR and ESG reporting. Karos provides data on shared rides and estimated CO2 savings so you can document the environmental impact of your mobility initiatives.

Can carpooling help reduce parking pressure at our site?

Carpooling reduces the number of single-occupancy cars travelling to your site, which lowers demand for parking spaces and the associated costs. It is often a faster and cheaper solution than building new parking capacity.

How can Karos help our company with employee commuting?

Karos helps companies reduce home-to-work commuting challenges by connecting employees who live and travel along similar routes. This eases parking pressure, lowers commuting costs for staff and supports your corporate sustainability goals, especially for sites in areas with limited public transport.
