Travel data with
verified CO₂ on every itinerary
Tictactrip returns the CO₂ footprint per passenger for every train and bus itinerary — the raw material for climate-aware products, green filters and Scope 3 reporting.
Sustainability needs to be measurable, not just aspirational
Most travel APIs treat CO₂ as a marketing afterthought. Tictactrip was built around the opposite premise: emissions data is a first-class field on every search result, computed consistently across carriers and modes.
That single design decision unlocks an entire family of products: green filters on OTA search pages, carbon budgets in corporate travel platforms, employee-commuting tools, Scope 3 reporting dashboards, and climate-aware fintech features.
Tictactrip is a French company, operated under GDPR and EU law — a natural fit for European sustainability programs and government-adjacent climate initiatives.
- CO₂ emissions per passenger per leg, on every itinerary
- Consistent methodology across all 250+ carriers
- Mode-aware estimates (train vs bus vs intercity)
- Operational-profile adjustments per carrier
- Suitable for Scope 3 (category 6 & 7) reporting
- GDPR-compliant — French / EU jurisdiction
Why CO₂ data on every itinerary
The capabilities partners ship on day one.
Feed Scope 3 reporting
Each booking returns audit-friendly emissions per passenger. Aggregate them into corporate ESG dashboards, GHG accounting or carbon-budget products.
Comparable, not just a number
A consistent methodology across carriers means you can rank itineraries by carbon impact — not just price or duration — without ad-hoc normalisation.
Operated under GDPR
Tictactrip is a French company and runs the API under EU law — important for government, ESG and climate programs with strict data-handling requirements.
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 stays consistent across operators so values are directly comparable.
Can I use the emissions data without booking through Tictactrip?
Yes. Many climate-tech partners hit the search endpoint purely for emissions data — for example to power green decision-support flows even when the booking is handled elsewhere.
Is the data suitable for Scope 3 corporate reporting?
The emissions returned per booking are designed to feed Scope 3 (category 6 business travel and category 7 employee commuting) workflows. Our team can walk through methodology details on request.
Does the API let me filter by lowest emissions?
Each itinerary returns its CO₂ footprint in a consistent field. You apply your own sorting and filtering logic — most partners surface a "Greenest option" badge or sort the cheapest itineraries by CO₂ as a secondary criterion.
