Calculation of air travel emissions

Posted by Morgan White on September 11, 2014

Good morning all,

To get air travel emissions, miles must be entered into the Clean Air-Cool Planet calculator. 

Mileage data is not tracked for our campus. So, I request air travel dollar data from OBFS.  This number has become more reliable in recent years because of the T-card implementation.


Air travel dollars are converted into miles using the passenger yield (fares per mile) data from Airlines for America


In fy 2013, dollars spent on air travel was $9,283,105.82.  Passenger yield was $0.1514 (this is fy 12, apparently fy 13 was not yet available).


Divide the two, and you get 61,477,522
