Sacramento County Idle-Free Schools, an Idle-Free California Inc. funded project, is being implemented by Idle-Free California for the 2017-18 school year. Following recruitment of interested science, math, social science, social studies, STEM, and environmental studies teachers — with approval of school administrations — three middle schools within the Unified School Districts of Sacramento County are participating in long-term, student-led studies/campaigns that are addressing the health, climate, and energy impacts of vehicle idling on school grounds. Idling “hot spots” are a common occurrence at many schools, for instance when parents sit in their vehicles with engines running while waiting for students during afternoon pick up.1
These studies/campaigns promote science, mathematics, and project based learning by engaging students in a before and after study of idling vehicles; they further provide students with the opportunity to learn how to run a public service campaign and empower them to make a positive difference in the school community.
These campaigns are modeled on the excellent EPA Region 8 Idle Free Schools Toolkit.
Note: Participating school parents, PTOs or school parent clubs are also encouraged to participate!
1These campaigns do not address idling of school buses as California already regulates the idling of school buses and other heavy-duty vehicles.
Why an idle-free schools project?
• The EPA states: "Idling vehicles contribute to air pollution and emit air toxins, which are pollutants known or suspected to cause cancer or other serious health effects. Monitoring at schools has shown elevated levels of benzene, formaldehyde, acetaldehyde and other air toxics during the afternoon hour coinciding with parents picking up their children. Children’s lungs are still developing, and when they are exposed to elevated levels of these pollutants, children have an increased risk of developing asthma, respiratory problems and other adverse health effects. Limiting a vehicle’s idling time can dramatically reduce these pollutants and children’s exposure to them."
• The California legislature, in 2016, adopted ACR 160, a resolution that addresses the issue of vehicular air pollution. Specifically, it encourages motorists to not idle their motor vehicles near places where children congregate. This resolution lists many compelling reasons to avoid idling at schools or just about anywhere.
• In addition to the benefits in idling reduction these efforts provide, (1) students learn organizational, analytical and communication skills as they perform data analysis, are empowered by showing drivers the significant benefits in shutting off engines when parked, and take pride in making a positive difference in their school community, and (2) motorists learning of the benefits potentially apply them beyond schools.
Idle-Free California, previously Idle-Free Vermont, has successfully implemented idle-free schools campaigns in Vermont for several years. The most recent year of school participation yielded a 46% reduction in idling. Details here. Teacher commendations. Shelburne Community School campaign. We are excited to continue these efforts in the Golden State!
How it works and what's included!
These studies/campaigns utilize a five step process:
(1) Sept. or Oct.: An initial training session in the classroom is given by Idle-Free California Executive Director Wayne Michaud. It features a 45 minute PowerPoint and video explaining what idling is, the benefits in avoiding it, and campaign steps. Handouts for students and teacher toolkit are provided.
(2) Oct. or Nov.: Starting 15-20 minutes before afternoon dismissal (if possible) five to seven students conduct a study of initial unobtrusive data collection per day for four school days, measuring the amount of idling. Vehicles are timed for how long they idle; from this information, fuel consumption and CO2 emissions can be calculated.*
(3) Nov.: Schools install two no-idling signs provided by the project and announce support of the idle-free campaign in the school newsletter and/or on the school website.
(4) Feb.: Students conduct a driver contact event for two days. With a display of idle-free signs made by students and parents, students approach parents/guardians in vehicles and follow a memorized script as they explain the benefits in avoiding idling; drivers receive informational handouts provided by the project.
(5) April: In the same manner as step 2, students conduct a study of final unobtrusive data collection for four days.* Then "before" and "after" data are compared to determine a difference.
*For steps 2 and 5 schools optionally are welcome to supplement data collection by utilizing emissions analyzer and sensor equipment that schools or districts may have available.
Note that students are made aware idling when parked can be necessary such as for the well-being of passengers that are infants, frail elderly, or pets in weather extremes. They also learn that a small number of vehicles — hybrids such as a Toyota Prius or electric vehicles such as a Nissan Leaf or Tesla — seldom idle or do not idle when running.
School administration commitment to campaigns:
Once a teacher is interested in project participation, the teacher is asked to obtain verbal approval of the school administration; if written approval is required by the school, an approval form is available.
The school administration is expected to support the campaign in the following ways:
• install at least one of the two NO IDLING signs provided by the project in the school pick up area, following initial data collection (Oct. or Nov.)
• announce support for the campaign in the school community, following sign installation (Oct. or Nov.); project provides suggested talking points for school newsletter and/or school website
• sustaining the effort: in succeeding years, schools are strongly encouraged to remind the school community to avoid idling several times each year

DATA INCOMPLETE. Explanation from school: Students not given permission to be dismissed early to observe
vehicles waiting prior to dismissal. Students could only observe vehicles from the time of dismissal when vehicles in
line slowly move forward to school entrance.
To address this issue, participating schools in future efforts must agree to allow students to conduct observations at
least 15 minutes prior to dismissal.
