GREEN DRIVING AMERICA (and Idle-Free California and Idle-Free VT)

IDLE-FREE SCHOOLS CAMPAIGNS MEASURED IMPACTS: SCHOOL YEARS

UPDATED 2024

 

Calculations based on reductions (or increase) in fuel consumption and CO2 emissions for school year, relative1 to the number of vehicles observed - initial vs final measuring

 

2014-2015: Vermont six schools: 31% idle reduction overall

- Hartford High School- 85% idle reduction  Reduction: fuel: 112 gal; CO2: 2,240 lbs

- St. Albans City School- 58% idle reduction  Reduction: fuel: 58 gal; CO2: 1,160 lbs

- Champlain Valley Union HS- 36% idle reduction Some final data incomplete

- Essex Middle School- 20% idle reduction  Reduction: fuel: 15 gal; CO2: 300 lbs

- South Royalton School- 5% idle reduction  Reduction: fuel: 3 gal; CO2: 60 lbs

- Middlebury Union HS- 16% idle increase  Increase: fuel: 7 gal; CO2: 140 lbs

 

2015-2016: Vermont five schools: 41% idle reduction overall

- Shelburne Community School- 74% idle reduction Reduction: fuel: 195 gal; CO2: 3,892 lbs

- Lyndon Town School- 58% idle reduction  Reduction: fuel: 97 gal; CO2: 1,940 lbs

- Stowe Middle School- 39% idle reduction  Reduction: fuel: 22 gal; CO2: 440 lbs

- Main Street Middle School- 33% idle reduction Reduction: fuel: 14 gal; CO2: 280 lbs

- Hunt Middle School- 0% idle reduction   Reduction: fuel: 0 gal; CO2: 0 lbs

 

2017-2018: California two schools: 67% idle reduction overall

- Orangevale Open K-8- 67% idle reduction  Reduction: fuel: 499 gal; CO2: 9,980

- Katherine L. Albiani MS- data incomplete  Final measuring not conducted

 

2022-2023: California two schools: 75% idle reduction overall

- Eagle Peak Middle School- initial measuring campaign only

- Carlmont High School- 75% idle reduction  Reduction: fuel: 141 gal; CO2: 2,829 lbs

 

2023: Vermont one school

- Woodstock Union HS&MS- initial measuring campaign only

 

TOTALS: 16 CAMPAIGNS; 13 INITIAL AND FINAL MEASURED CAMPAIGNS - 41% IDLE REDUCTION AVG. DIRECT* FUEL REDUCTION (GALS.)-12 CAMPAIGNS: 1,149 (96 gal. per school avg.)

AVG. DIRECT* CO2 EMISSIONS REDUCTION-12 CAMPAIGNS: 22,981 lbs. (1,915 lbs. per school avg.)

*indirect unknown reductions by informed drivers beyond schools

 

1RELATIVE FORMULA EXAMPLE (Orangevale Open K-8):

initial vehicles observed: 67 x 1.925 = 129 (final vehicles observed)

initial gallons 175 day school year: 389 x 1.925 (based on 129 vehicles) = 749

final gallons 175 day school year: 250

DIFFERENCE: reduction of 499 gallons fuel consumption and 9,980 lbs. CO2 emissions
