Why we exist

We do the work most of the industry skips

Business travel is one of the largest, most stubborn corporate emission categories. Most of the carbon industry measures it broadly and sells offsets; we went deep on travel instead - on the harder work of actually cutting the emissions, and the cost with them.

Reduce first

The order matters: cut emissions at source, and offset only the genuine residual. Reduction is the hard part, so much of the industry skips to offsets. We do the hard part.

Cost and carbon aren’t in conflict

The most sustainable travel option is often the cheapest. Our platform helps organisations capture both savings simultaneously.

Complexity simplified, not hidden

Travel data is messy, policies are nuanced, and stakeholder interests compete. We make that complexity legible, not invisible.

Depth over breadth

We don’t cover every emission source. We go deep on travel because specificity is what drives action.

Behaviour change isn’t easy

RouteZero identifies the precise balance of carbon, cost and experience that unlocks better company outcomes.

Founders

Built by people who know the problem

Domain experience from inside large multinationals, and engineering that runs from satellite systems to large-scale data platforms.

Dan Brown

Dan Brown

CEO & Co-founder

Having seen the challenge of managing travel emissions first-hand while working in large multinational organisations, Dan co-founded RouteZero to bring transparency and accountability to corporate travel data. At RouteZero, he works with customers to turn sustainability commitments into measurable reductions, embedding sustainable choices into everyday travel decisions to meet the IPCC’s challenge of halving emissions by 2030.

Albie Baker-Smith

Albie Baker-Smith

CTO & Co-founder

With a background in software engineering, from satellite systems to large-scale data platforms, Albie co-founded RouteZero to tackle a problem where technology can deliver measurable, real-world impact. He leads the platform’s technical strategy, spanning data architecture, emissions modelling, and product design. His primary engineering challenge is building the intelligence layer that makes optimal journeys the natural choice, at scale and without compromise.

The platform

Three products, one platform

Understand your emissions, model the changes before you commit, and act at the point of booking. Each works on its own; together they turn raw travel data into lower-carbon, lower-cost trips.
