Travel emissions down.
Costs down.

AI that finds the lower-cost, lower-carbon version of the trips your people already take, and surfaces it inside your booking tools - your actual trips and your actual savings, not a generic AI answer or an industry average.

How RouteZero works

Every trip has a better version. Our AI finds it.

Two flights on the same route, 30 minutes apart, can differ on both carbon and cost - one flies a newer, cleaner aircraft. A first-class rail seat can come in cheaper and greener than an economy flight. RouteZero finds savings like these across your whole programme, and helps your people take the better trip - shown right inside the booking tools they already use.

The 9:30 beats the 9:00It flies an A320neo - newer engines and winglets burn less fuel. Lower carbon and a lower fare than the 9:00.

RouteZero Foresight

The CFO chose the bigger CO₂ cut.

RouteZero models any change before you roll it out - a nudge, an incentive, a required swap - on your real travel history, so you see what each one saves. Start small and ramp up; once finance sees the numbers, the bolder move often wins.

RouteZero Data

Flights that never flew.
Refunds logged as trips.
Exchanges counted twice.
Fees that aren't travel.
Duplicate bookings.
Flights that never flew.
Stripped out, so the AI builds on real data.

Travel data lands from a dozen systems - booking tools, expense, card, car hire - and the emissions figures are patchy or plain wrong. RouteZero ingests any source, cleans and audits it, and applies advanced methodologies: one defensible baseline, accurate enough for an auditor - and the foundation of every saving the AI finds.

Questions

Frequently Asked Questions

No. RouteZero works alongside whatever booking platform you already use, whether that's Concur, Navan, TravelPerk, or anything else. No integration project, no workflow change for travellers or IT.

We work with whatever you already have - booking provider exports, expense reports, car hire records. We handle the collection and cleaning. You don’t need to prepare anything.

Not in our experience. Logicalis cut emissions by 42% while travelling more kilometres to meet more customers. The opportunity is usually in travelling smarter, not less.

RouteZero focuses on business travel - the flights, trains, hotels, and car hire your people book for work, at home and abroad (Scope 3 Category 6). Commuting matters too, and many organisations are already working on it; it’s a separate category we don’t cover. Business travel tends to be a larger share of emissions than it first looks, and the harder part to measure and act on - which is where we focus.

We reduce emissions; offsetting handles what’s left, in that order. Every tonne cut at source is a tonne you don’t pay to offset. Two things shrink the bill: lowering flight emissions at booking (a cleaner aircraft, a lower cabin, a more direct routing), and an accurate baseline, so you’re not buying credits for emissions that were never real - refunds, duplicates, double-counted exchanges. Offsetting then covers a smaller, genuinely unavoidable residual, not the whole footprint.

That’s the norm, not the exception. Messy, multi-source data is exactly what we’re built for. You don’t need clean data to get started. You just need data.

No. Most organisations start with RouteZero Data to get a clean baseline. Foresight and Intelligence build on that when you’re ready. Start wherever makes sense.

We use Cirium for flight-level fuel burn, Green Travel Pledge for rail, and DEFRA factors for car and hotel, with full methodology notes so every figure is auditable and SECR-ready.

Measurement is a necessary first step, but it doesn’t reduce emissions on its own. Many of the organisations we work with had sophisticated dashboards and carbon budgets before engaging RouteZero. What they lacked was a way to move from knowing their numbers to changing the trips that drive them - route by route, booking by booking.

Yes. We handle data to industry-standard security practices and have worked with organisations including HM Government where requirements are especially stringent.
