Share the ride.
Split the cost. Spare the planet.
Every ride counts.
RIDR is the fair ridesharing platform: put trips that are already happening to better use, reward drivers fairly, and give riders an affordable way to get there. Fewer cars, freer roads, less CO₂.
A smarter, fairer way to move.
RIDR connects drivers who are already on the road with riders heading the same way. Payments are processed securely by Stripe, our licensed payment provider. RIDR is an intermediary software platform, not a transport company.

See what a shared ride moves
In commuter traffic there are on average just 1.1 people per car. Those empty seats are the lever. Set the sliders to your anchor and see the yearly effect. Every assumption is disclosed and adjustable below.
CO2 saved
Directly tied to fossil fuel saved. A countable currency for ESG reporting.
Vehicle-km avoided
Kilometres no car drives anymore.
Fewer cars (peak)
Fine dust avoided
Tyres, brakes, road. Stays even with EVs.
Fuel costs saved
For the participants per year.
External costs relieved
Climate, health, accidents, noise. For society.
Parking area freed
Vehicle-kilometres of participants per year
Assumptions and method
Method: avoided vehicles = participants x adoption x (1 minus 1 divided by occupancy). Annual km per commuter = distance x 2 x work days. Avoided vehicle-km is the product. CO2, fine dust, fuel and external costs scale linearly with avoided vehicle-km. Parking spaces equal the vehicles removed at peak time.
Default data basis: commuter occupancy 1.1; non-exhaust fine dust up to 60 percent of traffic fine dust; car external costs about 11 cents per passenger-kilometre, here applied conservatively per vehicle-km; surface parking space about 28,500 euro, from 25 m2. Sources: German Federal Parliament/DIW, Federal Environment Agency (UBA), ifeu, bpb, Allianz pro Schiene.
Honest limit: driver detours and the exact displaced mode are simplified. For robust communication, use the real net effect from the app data.
