A livery applied at your own aircraft saves a flight that carries no passengers and no cargo. Pick the type and how long that flight would have been, and the number is right there.
Sustainability claims are only worth something if the arithmetic is on the table.
The same method lies behind the figure we publish for all projects since 2019, so the two can be compared.
Every one of these would make the result larger. We would rather publish the conservative figure.
Two hours is a realistic distance to the nearest free booth.
| Aircraft | Fuel not burnt | CO2 avoided | Beech trees, one year |
|---|---|---|---|
| Airbus A320 | 5,200 kg | 16.4 t | 1,315 |
| Airbus A321neo | 4,800 kg | 15.2 t | 1,213 |
| Boeing 737-800 | 5,000 kg | 15.8 t | 1,264 |
| Airbus A330-300 | 11,000 kg | 34.8 t | 2,781 |
| Boeing 767-300ER | 12,400 kg | 39.2 t | 3,135 |
| Boeing 777 | 19,200 kg | 60.7 t | 4,854 |
| Boeing 747-400 | 21,200 kg | 67.0 t | 5,359 |
Multiply by the number of aircraft in the programme and a fleet rebrand turns into a figure your sustainability report can use.
From the figures we use in our own project planning, per type, in kilogrammes per hour. If your operations department has its own figure for the type, use theirs — the arithmetic on this page is simple enough to redo with your own input.
Burning one kilogramme of jet fuel releases about 3.16 kilogrammes of CO2. That is the factor published by ICAO; Eurocontrol uses 3.15. We use a published value rather than one of our own, so that anyone can check the result.
Figures in older material of ours were calculated differently — the ones on this page are current.
No. The calculation covers one leg only. An aircraft ferried to a paint shop normally flies back as well, so in practice the saving is roughly twice what you see here. We publish the single-leg figure because it is the one we can defend without discussion.
The method is on this page, so your own team can reproduce and review it. For a concrete project we will put the calculation in writing with the aircraft, the assumed flight time and the resulting figure, so it can be filed rather than screenshotted.
Send the types and how many aircraft the programme covers, and you get the calculation as a document with the assumptions named.
