CO₂ on every itinerary
Each itinerary carries an estimated CO₂ footprint per passenger per leg — the bedrock of climate-tech products that need to compare modes, routes or carriers.
Solution · Green-tech & sustainabilityTravel data with
Travel data with
verified CO₂ per passenger
Build climate-aware booking, employee commuting platforms and carbon-budget products on top of European rail and bus inventory.
Climate platforms need real inventory, not just emission factors
Most sustainability tools start with emission factors — but a useful product needs to connect those numbers to actual bookable journeys. That's where Tictactrip fits.
We expose 250+ European train and bus carriers through one REST API. Every itinerary returns CO₂ emissions per passenger per leg, alongside price, duration and carrier metadata — the raw material green-tech products need to compute alternatives, score business trips or run carbon budgets.
- CO₂ emissions per passenger per leg, on every itinerary
- 250+ rail and bus carriers across Europe
- Multimodal itineraries to surface lower-emission alternatives
- Real-time pricing for spend-and-emissions comparisons
- End-to-end booking when you want to close the loop
- GDPR-compliant — operated under French and EU law
Why Tictactrip for green-tech & sustainability
The capabilities partners ship on day one.
Surface low-carbon alternatives
Compare a short-haul flight to high-speed rail on the same origin-destination pair. Build product flows that nudge users toward the lower-emission option.
Feed Scope 3 reporting
Aggregate booking-level emissions into corporate Scope 3 reports, ESG dashboards or carbon-budget products. The data structure is consistent and audit-ready.
EU-based and GDPR-compliant
Tictactrip is a French company operating in compliance with the GDPR. A natural fit for European sustainability and government-adjacent climate programs.
Integration
One REST call, multimodal results
The same endpoint powers every Tictactrip integration. Authenticate, send a search payload, and receive itineraries with price, duration, carrier and CO₂ emissions. Then book through /book and deliver tickets to your users.

}'Frequently asked questions
The points product and engineering teams check before integrating.
How are CO₂ emissions calculated?
Emissions are estimated per passenger per leg based on the mode (train or bus), the carrier-specific operational profile and the leg distance. The methodology is consistent across operators so values are directly comparable.
Can I use the emissions data without booking through Tictactrip?
Yes. Many climate-tech partners use the search endpoint to surface emissions for decision-support flows even when the actual booking is handled by another channel.
Do you support employee-commuting use cases?
Yes. Several green-tech partners build employee-commuting platforms on top of Tictactrip — combining home-to-office routing with the CO₂ data the API returns.
Is the API suitable for Scope 3 / GHG accounting?
The emissions returned per booking are designed to feed into Scope 3 (category 6 business travel and category 7 employee commuting) workflows. Our team can walk through methodology details on request.
