RouteZero

Core Features

RouteZero takes a data-first approach to business travel, treating emissions, spend and traveller behaviour as parts of one system. It ingests bookings and expense data, applies transparent Scope 3 methodologies, then uses behavioural insights and scenario modelling so climate goals translate into everyday travel choices. Within that approach, key capabilities include:

• Granular carbon engine – Calculates emissions for flights, rail, hotels and other trips using methods aligned with the GHG Protocol’s Scope 3 Category 6 (Business Travel) and defaulting to DEFRA emission factors.

• Integrated spend and emissions tracking – Consolidates bookings and expense claims to show CO₂e and spend by traveller, department, project and supplier, helping teams see where emissions and budgets concentrate.

• Policy Lab scenario modelling – Lets organisations test interventions such as air-to-rail shifts, class changes or new approval rules, projecting their cost and emissions impacts before rollout so stakeholders can agree evidence-based policies.

• Regulatory-aligned reporting & auto-export – Brings Scope 3.6 data from multiple providers into one place and outputs it in formats aligned with frameworks like CSRD, CDP and B Corp, supporting supply-chain transparency for business travel.

• Behaviour-change and incentive tools – Uses behavioural psychology and nudges to reward employees for choosing lower-carbon routes, enabling reported emissions and travel costs to fall simultaneously in customer pilots.

• Multi-modal travel optimisation – Helps users compare and book rail, flights and hotels while automatically providing lower-carbon, competitive options.

Closing Insights

RouteZero grew from founder Albie Baker-Smith’s attempt to find the lowest-carbon route for his own travel, evolving from a University of Bristol carbon calculator into a platform aimed at large enterprises and public institutions with significant business-travel footprints. Its distinguishing feature is the way it combines granular, standards-aligned carbon accounting with behavioural science, AI-assisted policy modelling and cost analytics, so travel decisions can be changed at scale rather than offset after the fact.

Customers such as Logicalis, the UK’s Natural Environment Research Council and the University of Bristol report reductions in business-travel emissions and costs, illustrating how RouteZero adapts to different governance and reporting needs across sectors. Its momentum is reinforced by backing from investors and incubators including Innovate UK, ESA BIC UK, Setsquared Bristol, Geovation and the University of Bristol Endowment.

Given rising scrutiny of Scope 3 supply-chain emissions (often the largest share of corporate footprints) where business travel (Scope 3.6) is a material component, specialised tools like RouteZero are increasingly significant. With business pricing tiers (Starter from £450/month, Growth from £1,500/month and Enterprise by negotiation, plus a per-booking fee), integrations for travel-management and expense systems, and options for bespoke decarbonisation campaigns and consultancy from RouteZero experts, organisations can combine travel booking, carbon analytics and advisory support in one stack.
