Locations

If one sensor: leave sensor in one location for 1 week, then move locations every week.

If several sensors: leave each sensor in one location for a week

School: Drop of and pick up location

• Measure if CO2 is higher during drop of und pick up times than during the day
• Measure if CO2 in this location is on average higher than other locations
• How many people drop off and pick up their kids by car?
• How long or cars idle on average?

Green Spaces: A park, forest, field

• Measure if CO2 fluctuates during the day (according to the diurnal cycle)
• Does the green space contain many trees? What kind of trees?
• How big is the green space? Is it close to major roads?

Major road

• How is the average CO2 compared to other locations?
• Is the CO2 higher or lower at different times? E.g. during morning and evening rush hour, weekends vs weekdays?

Analysis

Compare measurements between the different locations

• Are the average CO2 measurements different between each location?
  • Compare hourly measurements & 24h average
  • What are the possible reasons for the differences in measurements between the locations?
  • Think of solutions to reduce the CO2 measurements for each location

Compare the measurements at each location throughout the day and week

• Does the CO2 stay constant throughout the day or week?
  • Are there specific times or days when the measures are higher than usual? Are those times constant or random?
  • What are possible reasons for the higher measurements at certain times?
  • Think of solutions to reduce the CO2 measurements during the peak CO2 times

Advanced Actions

Turn cars off during drop off and pick up

• Measure one week with normal drop off and pick up
• Implement a “Climate Week”, where cars are required to be turned off while waiting to pick up their children
  • Measure if there is a difference between the two weeks, especially the peak hours
  • Advocate at the school to implement a permanent policy

Is your school suitable for the students to walk or cycle to the school?

• Implement a “Climate Week”, where students are urged to walk or cycle to the school. (Students can track how many km/miles they walked or cycled, or how many days of the week they did that instead of commuting by car)
• Measure the week before and then measure during “Climate Week”
  • Are there differences in CO2 levels between the two weeks?
  • Was there a reduction in traffic, parking needs etc?
  • Think of ways you could improve and promote active commuting to the school
