Private Jets
The real carbon cost of a flight hour
A light jet burns about 1.3 to 2.2 tonnes of CO₂ per flight hour; a heavy jet 2.8 to 5.3. Durable removal for one light-jet hour costs roughly $740 to $1,250 at today's prices.

~2 t per hour
Massive Carbon Footprint
Transport & Environment puts the average private jet at about 2 tonnes of CO₂ per flight hour.
Not counted
Contrails & Radiative Forcing
Contrails and other non-CO₂ effects add warming on top of the CO₂. Neutral's estimates count CO₂ only and say so.
5–14x
Fuel Inefficiency
Transport & Environment estimates private jets are 5 to 14 times more carbon-intensive per passenger than commercial flights.
