The table illustrates the figures of fuel consumption, carbon dioxide emissions, and flight cost per hour for nine popular private jets.
Overall, it is clear that aircraft with higher flight costs use more fuel and emit more CO2. In addition, Gulfstream III has the highest figures in all three categories, while Cessna CJ II has the lowest numbers.
Looking at the lowest cost group, three planes cost $2,700 per hour to fly. Cessna CJ II consumes 136 gallons of fuel per hour and emits 3,002 lbs of CO2, which are the lowest figures in the table. Beechjet 400 requires more fuel at 182 gal/hr and produces 4,017 lbs of CO2/hr. Hawker 400XP uses slightly higher fuel, at 188 gal/hr, and releases 4,149 lbs of CO2/hr.
Regarding the remaining aircraft, three models cost $4,500 per hour. Cessna Citation XLS consumes 204 gal/hr. Learjet 60 records 209 gal/hr and 4,613 lbs CO2/hr, which are the highest in this group. Hawker 800XP consumes 188 gal/hr, which is the same fuel use and emissions as Hawker 400XP, but has a higher cost. For the most expensive group at $6,750 per hour, Challenger 605 consumes 280 gal/hr, the lowest in this group. Gulfstream 550 emits 8,342 lbs CO2/hr, ranking second highest overall. Finally, Gulfstream III records 488 gal/hr and 10,078 lbs CO2/hr, making it the highest in all categories.
