Everything CarbonTrack
does for you.

The only platform built specifically to capture, calculate and report Scope 3 business travel and employee commuting emissions. At source, in real time, audit-ready.

We exist because the data problem
has never been solved properly.

Every ESG platform assumes clean data arrives at their door. Nobody fixed the broken step before it. Your finance team logs flights in emails, engineers record site visits on receipts, and sales reps forget to log anything at all. CarbonTrack starts at the trip. Not the spreadsheet.

The Problem We Solve

Every other tool starts too late.

The broken step in carbon reporting has always been data collection. CarbonTrack fixes it.

✗ Without CarbonTrack

  • Someone emails their mileage to a shared inbox
  • Someone manually copies it into Excel
  • Google Maps used for flight distances (wrong methodology)
  • DEFRA factors looked up manually, possibly outdated
  • Spreadsheet cleaned and formatted. Hours of work.
  • Report generated with no formula trail
  • Auditor asks "how did you calculate this?" and panics

✓ With CarbonTrack

  • Your team member logs the trip directly. 30 seconds.
  • Distance calculated instantly using Haversine for flights and Google Maps for road/rail
  • DEFRA 2025 factors applied automatically to 6 decimal places
  • Emissions calculated in real time. kgCO2e shown immediately.
  • Audit trail created for every single trip automatically
  • Dashboard updates live. No waiting for year end.
  • Auditor asks "how did you calculate this?" and you show them instantly
