Data & Reporting

Reliable emissions figures. Board-ready reports. Actionable insights.

Consolidate fragmented travel data into one defensible baseline for cost and carbon - accurate enough to stand behind, and solid enough to set once instead of restating it next year. The foundation your reports, policy changes, and booking decisions build on, with the DEFRA-compliant methodologies your auditors require.

The problem

Travel data is harder to work with than it should be

Sustainability teams spend weeks wrangling data instead of reducing emissions. Sound familiar?

Fragmented sources

Booking provider reports, expense data, car hire, hotel , each in a different format, often changing between requests. Piecing it together is a job in itself.

Unreliable emissions

Booking providers include emissions figures but the methodology is unclear, factors are often misapplied, and companies have had to rebaseline because the numbers were wrong.

Back-and-forth

Chasing providers for corrections, re-requesting data in different formats, resolving missing columns. Time spent on data wrangling instead of reducing emissions.

No clear picture

Without reliable data, you cannot report accurately, identify the biggest levers, or measure whether your existing guidance is actually being followed.

How it works

From raw data to reliable emissions, automatically

RouteZero handles the full pipeline - ingestion, cleaning, auditing, enhancement, analysis, and reporting - so you get defensible figures without the manual work.

Ingest

Provide your data in any format - booking provider reports, expense exports, car hire data. RouteZero can also liaise directly with your travel management company to request and chase data on your behalf, so collecting it stops being your job.

Clean

Duplicates, refunds, exchanges, and ancillaries are automatically identified and removed, so your totals aren’t inflated by bookings that never flew. Every reconciliation is traceable to its source row.

Audit

Automated checks verify data quality: mileage, emissions cross-validation, missing data periods, timeline completeness, and booking uniqueness, so a wrong figure is caught here, not in front of your board.

Enhance

Flight numbers resolved via Cirium, distances independently recalculated, emissions computed using the right methodology for each journey: Cirium, Google Emissions, Green Travel Pledge, or DEFRA, so every figure holds up to scrutiny.

Analyse

Emissions, costs, and travel patterns broken down by type, route, office, and time period, so you can see where your biggest reductions and savings actually are. Guidance compliance measured at the trip level.

Report

SECR-ready reports with full methodology documentation and sensitivity analysis, ready for your board and auditors to sign off without a round of follow-up questions.

Data quality

Every booking checked. Every figure verified.

Automated, AI, and manual checks catch every duplicate, refund, and misapplied factor before it reaches a report - so your figures hold up when an auditor, or your board, asks how you got them.

Reporting

Board-ready reports with auditor-ready methodologies

SECR-compliant reports with full transparency over data sources, reconciliation steps, and calculation methods.

Everything your auditors need

SECR-compliant Scope 3 Category 6 reporting, ready to drop straight into your disclosure

Full methodology document covering emission factors, distance calculations, data reconciliation, and sensitivity analysis, so every figure can be traced back to its source

DEFRA conversion factors with radiative forcing on flights

Methodology-agnostic: Cirium, Google Emissions, Green Travel Pledge, or DEFRA, whichever the reporting context requires

Variance analysis vs provider-reported figures, so when your numbers differ from your TMC’s you can explain exactly why instead of being challenged on it

Biggest opportunity: advance booking

Only 22% of trips are booked 14+ days in advance, affecting 1,205 trips. Improving to 50% could save ~£180k and reduce emissions by 3.2%.

Questions

Frequently Asked Questions

Carbon-accounting platforms tell you what your emissions were. RouteZero is built to act on them, cutting carbon and cost together. The audited baseline is the foundation, not the finished product: because every figure traces back to the individual trips behind it, you can model policy changes on real journeys and surface lower-carbon alternatives at the point of booking. Most of the organisations we work with already had dashboards and budgets. What they lacked was a way to turn the numbers into changes to the trips that create them.

Any format your booking provider supplies. CSV, Excel, PDF reports. RouteZero’s ingestion pipeline handles the parsing. If formats change between requests (which happens often), we adapt automatically.

An initial baseline is typically ready within a few weeks, depending on data complexity. Ongoing reporting is faster as the pipeline learns your data patterns. We handle provider communication so you are not waiting on back-and-forth.

We are methodology-agnostic. We support DEFRA conversion factors (standard for SECR), Cirium flight fuel burn data, Google Emissions APIs (including contrail modelling), and Green Travel Pledge for detailed rail emissions. We use whichever approach your reporting context requires.

Yes. With your permission, we liaise directly with your travel management company to request data, chase corrections, and resolve format issues. You receive the final output, not the headache.

RouteZero consolidates data across booking provider reports, expense systems, car hire providers, and hotel bookings into a single unified view. Overlapping datasets are deduplicated automatically.

We support common standards like SECR (Scope 3 Category 6) out of the box, and each report includes a full methodology document covering emission factors, distance calculations, data reconciliation, sensitivity analysis, and known limitations. If your organisation has specific reporting requirements, we can work with you to tailor the output to match.

Every booking passes through automated audit checks: duplicate detection, mileage verification, emissions cross-validation, missing data periods, timeline completeness, and more. Issues are flagged and resolved before figures are finalised. Every reconciliation is traceable to its source.
