Co2 Emissions Reduction via formation flight
I had a quick look back over some of my PhD work in preparation of a new paper I’m writing. I found it slightly mad that I never really included any numbers on Co2 emissions.
So I’ve been working on some under the assumptions:
- The emissions index of CO 2 per kg of fuel burnt is estimated to be roughly 3.16 
- A rough estimate of 600 dollars per metric tonne of fuel 
Take Singapore Airlines as an example, on a single day some 200 flights could potentially fly in 100 formations pairs. This would save on average 6.7% of fuel against those same flights flying solo. This works out at 610 tonnes of fuel saved, and as a direct result would burn roughly 1,929 tonnes fewer of Co2. Not only that but they’d save 366k in the process but simply not buying the fuel.
That’s for a single day.
That’s like planting 704,085 trees a year and getting paid $133m for it.
Equivalent of planting 80 per hour:
And getting paid $190 per tree at the same time
