Fleet emissions audit · Free · Instant
Three inputs.
A directional CO₂e estimate for your fleet.
Tell us your fleet size, EV share and shape. We'll show you a DEFRA-aligned estimate of annual emissions in ten seconds — no upload, no sign-up. Numbers are directional (±20%); the live Orbis platform replaces them with telemetry.
Cars, vans, HGV — anything that drives.
PHEVs and hybrids count as ICE for this estimate.
What's the fleet mix?
Mixed assumes 75% cars / 25% vans — typical UK commercial-fleet mix excluding HGV. HGV fleets need a different conversation — selecting it opens a contact form.

Your fleet is 10% BEV. The UK ZEV mandate targets 33% of new cars registrations in 2026 — measured cumulative parc share is currently ~5.8%. You're ahead of the typical trajectory.
This is a directional estimate. Orbis replaces every figure with telemetry.
Auditor-defensible, line by line, drawn directly from the vehicles.
A real Q1 2026 SECR — anonymised 223-vehicle fleet, 80.08 tCO₂e, every figure traceable to vehicle-level source. See the full sample →- Three-method reconciliation per vehicle — engine ECU, odometer-based, tank-level drawdown
- GHG Protocol + DEFRA 2025 compliance — Scope 1, 2, and 3 (well-to-tank + production)
- No aftermarket dongles, no field engineering — over-the-air data only
- Quarterly reports, sign-off ready — like the one above
