1) Print/copy worksheets (see below).
2) Determine round trip distances from zip codes to the event location.
3) Assign volunteers and plan logistics to record data as vehicles arrive.
4) Record data on vehicles during the event. Volunteers can observe how many people are in each vehicle as they park. Most people won’t know the distance they’ve traveled, so it will be quicker to ask each driver what their zip code is. Be sure to include all vehicles—participants, volunteers, event officials, vendors, flaggers, etc.
5) Post event, total up vehicles, mileage and emissions.
6) Complete a report, including a waste audit and vehicle metrics.
7) Complete the EDiSN Post Event Survey. Keep a record to compare metrics year to year.
8) Consider doing carbon offsets for your event.
A typical passenger vehicle on the road today has a average fuel economy of about 22 miles per gallon. A 10 foot Uhaul truck gets 12 MPG and the larger trucks get 10MPG. Every gallon of gasoline burned creates about 8,887 grams of CO2 (19.6 pounds). The worksheets provided assume a 22 MPG.
