Business travel counts too.
Grey-fleet mileage claims, rail, air, road and hotel nights sit inside the same assessment as the fleet itself. Add each trip below and this page totals it instantly — itemised, with the exact published factor shown against every line, and nothing sent anywhere.
Figures are the UK Government's own 2026 GHG Conversion Factors for Company Reporting (DESNZ), used unmodified. See the published dataset.

This calculator runs entirely in your browser. Closing or reloading the page clears it — download the CSV first if you want to keep a copy. Totals here are self-assessed, exactly like the rest of the GreenTurtle Standard: not an audit, not a third-party certification.
Already run an expense platform that calculates travel emissions per transaction on the DEFRA/DESNZ method — Capture Expense, for example? That export is measured travel and drops straight into your assessment instead of re-keying it here.
