Hi

Had a look and couldn’t find anything but I’m carp at searching.

Does anyone know or can point me to where I could find some data on the co2 generated from burning 100LL, I’m looking from the POV of working out a cost to offset.

Thanks

That seems an awful lot. Tell me I have it wrong.


That's precisely what I thought, if it's kgs, which is the most obvious unit, that seems a lot per litre.

Edited to say, I've had a quick Google and that's probably right. :shock:

So from burning Avgas there is circa 2.5 times the mass of CO2 produced, in addition to the other by products.

Holy moly. :shock: What we need are CO2 burning engines. :thumright:

Well, I've learned plenty this morning, including not to post a question before my first coffee. Of course the units of the answer depends on the units you input.

I hope this fog burns off so that I can go and create 312.48 bananas worth of CO2.

I almost beat you to it and then I recalled I hadn't had my first coffee. :wink:

It's not looking good according to Windy. I've given up all hope of ever flying again here, due weather. :evil: :evil:

A carbon atom has an atomic weight of 12.

Avgas is approximately 85% carbon, and most of those carbon atoms will end up being combined with two oxygen atoms, each of atomic weight 16, to produce a CO2 molecule of weight 44.

The extra mass comes from the oxygen being dragged out of the free atmosphere by the combustion process.

The above is a vast oversimplification, but if you work it through with even those numbers, you come very close to the conversion factor in @Rob P ‘s post above.

Reading this, I though those figures sounded nuts, but a quick google for petrol produce a figure of around 2.4kg per litre on multiple sources. For example.

Can't reduce that, but we can support offsetting via tree planting to absorb some of it. Either directly if you or your airfield has spare space, by sponsoring tree planting schemes such as this one.

I suppose the the argument becomes, why not plant trees and not fly, therefore doing even more good!
