Many interesting comparisons and analyses can be made using the data from the results pages.
Note that the campaign results are calculated several ways. Here we explain the terms used, how the results are calculated, their units of measurement and what they tell about climate emissions on the way to school.
Note that for any of these kinds of results, you can also choose to show the results at different levels:
CO2 emission intensity
This figure indicates how carbon intensive the ”mix” of modes of transport used by the reporters is. For example, if most of the kilometers to school are travelled by car, the emission intensity will be higher than if most of the travel is by foot.
Unit of measurement: grams/kilometer/reporter
How is it calculated: The estimated CO2 emissions for the trip to school are summed together for all of the reporters, divided by the number of kilometers travelled and then divided by the number of reporters.
Number of reporters
This figure tells how many reporters submitted data in the campaign.
Unit of measurement: reporters
How it is calculated: The program counts up the number of reporters who have entered data.
Mean distance to school
This figure tells how far, on the average, reporters need to travel to get to school.
Unit of measurement: kilometer/reporter
How it is calculated: The program finds the sum of all the one-way distances to school registered and divides by the number of reporters.
Total CO2 emitted
This figure is an estimate of how much CO2 is put into the atmosphere by one day of one-way travel to school, by all reporters who have entered data.
Unit of measurement: kg
How it is calculated: The program finds the sum of estimated CO2 emitted by school travel reported by all reporters.
Mean annual CO2 emitted
This figure is an estimate of how much CO2 is put into the atmosphere from one year of travelling to and from school, for an average reporter.
Unit of measurement: kg/reporter/year
How it is calculated: Each reporter’s registered CO2 emission for a one-way trip to school is multiplied by 380 (to get 190 two-ways trips). The results is an estimate of that reporter’s CO2 emissions per year. All of the reporters’ annual emissions are then added together and the sum divided by the number of reporters, to get an average per reporter.
