The Carbon Cost of Flying Private, Route by Route
Real CO₂ emissions from the Flyius brokerage dataset — where private flying emits the most, and the levers that actually reduce it.
Updated 2026-07-10
A single private jet flight can emit up to 78,400 kg of CO₂ one-way. We measured the carbon cost across 811 routes — and, honestly, where the real levers to reduce it are.
CO₂ per flight, by cabin
The bigger the cabin, the higher the emissions. Average CO₂ per flight climbs steeply from a light jet to an ultra-long-range one — which is exactly where the first reduction lever sits.
The 15 most carbon-intensive private jet routes
Topping the list: New York → Maldives at 78,400 kg of CO₂ one-way on an ultra-long-range jet. Here are the 15 highest-emitting routes in the catalogue. Sort by CO₂, CO₂ per km or distance.

The cabin lever: same route, far less carbon
On New York → Maldives, an ultra-long-range jet emits 78,400 kg of CO₂ versus 33,600 kg on a light jet — roughly 2.3× more. Flying the smallest cabin that has the range for the trip is the single most effective way to cut a private flight's footprint.
The SAF gap
Sustainable aviation fuel can cut lifecycle emissions sharply — but it is available on only 2.8% of routes today (23 of the catalogue). Until supply scales, cabin choice and routing remain the levers within a traveller's control.
Methodology
CO₂ figures are indicative per-flight estimates from the Flyius brokerage dataset (snapshot 2026-07-10), covering 791 of 811 routes; the 15 shown are the highest-emitting by ultra-long-range CO₂, deduped to one direction per city pair. Structural catalogue estimates, not a time-series.
