Search tips:
  • This form will search for words in the title OR the description. If you would like to search for the same term(s) across both the title and description, enter the same search term(s) in both fields.
  • This form will search for any of the words you enter in a field, not the exact phrase you enter. If you would like to search for an exact phrase, put double quotes (") around the phrase. For example, if you search for Bike Path you will get results containing either the word Bike OR the word Path, but if you search for "Bike Path" you will get results containing the exact phrase Bike Path.

  1. Calculation of air travel emissions

    Offset Emissions from Plane Trips

    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

    Best,

    Stephanie

  2. Transportation Emission files

    Hello Transportation SWATeam,

    Per our discussion today, here are a couple of files and links.

    1. The most recent version of the Clean Air Cool Planet emissions calculator.
    2. Excerpts from the calculator as related to transportation emissions.  Note the tab called “data for average commute” explains the current math for the average commute distance. 
    3. 2007 mode-choice survey details: http://www.ihavemiplan.com/results/index.html
    4. 2011 mode-choice survey details: https://icap.sustainability.illinois.edu/project-update/mode-shift-update

    Both of the mode choice surveys were done in completely different ways and not exactly for the purpose we are using them.  It would probably be good to develop a survey specifically for this calculation purpose that can be administered by the UI in future years.

    Thanks,

    Morgan
