The bus is the most climate-friendly way to move a group

A 300-km school trip with 50 people generates around 450 kg CO₂ in a coach. The same 50 people in 30 cars (with an average of 1.7 people per car) would emit around 1,700 kg CO₂ – roughly 73% more. With 50 single-occupancy cars, emissions rise to about 5× the bus level.

On a per-passenger-kilometre basis, yes: at around 30 g CO₂/Pkm the coach is well below cars (≈145 g) and domestic flights (≈230 g) and on par with rail. The high load factor is the decisive factor – a fully occupied bus is essentially unbeatable in passenger transport.

Electric coaches have arrived in the market but aren't yet ubiquitous. The main barriers are range for long-haul (~400 km with current technology) and the fast-charging network. City shuttles, commuter services and shorter tours are increasingly running on electric power.

The values used here come from the German Federal Environment Agency (UBA, TREMOD model). They're averages; actual emissions vary by about ±20% depending on vehicle model, occupancy and driving style. For more precise calculation, vehicle-specific data is needed.

Direct matching between customers and bus operators reduces broker hand-offs with high drop-off rates. More matched requests mean more occupied coaches – and lower emissions per seat. The AI price calculator simultaneously keeps operator margins stable, so they can invest in modern fleets.

Honestly: most emissions come from the tours themselves, not our servers. We're working on an optional offset booking with certified partners. We consider it misleading to claim a platform is climate-neutral simply because back-office emissions are offset.
