## X4US Description
X4US is a shared mobility app that gives employees of partner companies and communities access to a fleet of electric vehicles for urban transportation. By sharing vehicles, we reduce the number of cars on the road, decrease traffic congestion, and contribute to carbon neutrality.

HOW IT WORKS

X4US operates through communities. Your organization—whether a company, residential complex, or another partner community—allocates you a balance that you can use for trips with the available shared vehicles. Every trip is recorded transparently, with clear information about distance traveled, duration, and cost at the end of the journey.

WHAT YOU CAN DO WITH X4US

• Access a multimodal fleet, including e-bikes, e-scooters, electric cars, and BEN vehicles

• Find available vehicles near you using the map

• Unlock vehicles with your smartphone via Bluetooth—no physical keys required

• View vehicle rules, instructions, and pricing before starting a trip

• Track your available balance and review detailed trip information

• Monitor your community’s positive environmental impact through intuitive CO₂ savings indicators

• Belong to multiple communities (company, residential complex, or others) using a single profile

• Manage your personal network and invite contacts to join your network

• Report issues directly through the app

ACCESS

X4US is available exclusively to employees and members of partner organizations. To use the app, your email address must be authorized by your organization. If your company or community is not yet an X4US partner, you can find more information at [PLACEHOLDER: website or corporate email].

ABOUT THE PROJECT

X4US is operated by BEN4US and developed by CEIIA – Centre for Engineering and Product Development, as part of the Be.Neutral Agenda for carbon-neutral mobility in Portugal.
