Carbon footprint

Our entire upcoming trip will total 26,312 air miles. At ~0.44 pounds of CO2 generated per passenger mile, this will create 6 tons of carbon footprint.

Our carbon footprint for this trip weighs almost as much as a Tyrannosaurus Rex.

If these calculations survive under the gimlet-eye of our friend Sean (who knows about such things), we’ll purchase carbon offsets from Terrapass when we get home. Sean, use the Comments, okay?

Please share with your friends!

  1. So freakin awesome! Thrilled to know you two are able to follow through on your big travel plans. Googled the airport codes I didn’t know, great route. Nepal seems to be stunning and I’ve heard the same about Sri Lanka. If I can be useful for your Delhi and Mumbai time, reach out. Enjoy!

  2. A “.gov” website has a short and clean answer at

    In short, 1 gallon of fuel = 6.3lbs. Burning fuel breaks a carbon (1=atomic wt 12) to combine with 2 oxygens from the air (16 each, or 32 per carbon) to form CO2. So now you have an atomic weight 3.7 times the fuel alone. Burning also breaks off H which combines with oxygen to produce H2O, which also has a weight, but we’re not all that worried about excess pure water.

    Points to think about: 1) there’s no new weight, it’s just that we only measuring the CO2 output, 2) An online carbon footprint calculator will include other greenhouse gases so your results will be higher (and there’s the carbon footprint to get the fuel into the airplane).

  3. PS- I just checked and the cost of well verified carbon offsets on the State of CA market is $15/ton. So your web source selling at $5/ton is strange. Why wouldn’t they just sell to CA and get $10/ton more? They must not be able to verify carbon capture to the requirement standards of CA State’s market. If you’re going to buy poorly verified carbon offsets, might as well buy into a forest preservation system. It’s not really capturing a equivalent of the carbon you’re producing, it’s a land protection scheme to avoid cutting down forest with possible future carbon benefits. These guys are $9/ton
