Your fart’s carbon footprint


According to Elgood (2007), humans produce up to 1.5 liters of gas per day.  I’m assuming all gas volume figures in this post are at standard atmospheric pressure.

According to Britanica, up to 10% of your farts are methane (not mentioned if by weight or by volume, I’m assuming volume), which makes .15 liters of methane per day.

Which means at 717 gram/liter, you fart up to 110 grams of methane per day.

According to the Intergovenmental Panel on Climate change, methane is about 23 times as potent a greenhouse gas as compared to carbon dioxide.

That brings us to the carbon equivalent of almost 2.5 kilos of CO2 per day just from farting.

Now, being that the CO2 emissions of a Prius are 104 gram/kilometer, that means that just by sequestering your farts, you would reduce your greenhouse footprint enough to offset driving 20 kilometers in a Prius per day.

And now you know.
