About this activity

Suitable for all Secondary School Pupils (KS3-KS5)

The Carbon Calculator Activity Card is an innovative way to calculate the carbon footprint of travelling to school. This can provide a good indication of how your school community’s travel choices impact the environment. Although there will always be limitations to these calculations, this estimate can provide you with a good indication whilst helping you to quantify the impact of your project.

What is Carbon Footprint?

​This is a measure of the amount of greenhouse gases such as carbon dioxide released into the atmosphere as a result of the activities of a particular individual, organisation, or community.​

​It’s possible to calculate the carbon footprint of travelling to school. There will always be limitations to these calculations but this estimate can provide you with a good indication of how your school community’s travel choices impact the environment. It can also help you to quantify the impact of your project.

Why not calculate your carbon saving?

Do you think your schools travel carbon footprint has increased or reduced? Repeat the calculations for last year or your baseline survey and compare the results!

Activity steps

1
Collect the data
Identify the modes of travel within your class and average distance travelled through a class survey. For the whole school activity, please see the carbon calculator guide.
2
Discuss
Ask students to come up with a definition of a Carbon Footprint and how it might be relevant to school travel. Ask them why we measure in CO2 emissions per passenger and not per vehicle.
3
Demonstrate
Calculate the CO2 emissions for car/motorcycle as a class and ask students why the distance is multiplied by 2 for both this mode and for car share (journey to return car home).
4
Calculate
Allocate different modes to pairs/groups of students to make the calculations, using the instructions table and formula on the links page. Ask them to enter their figures in the totals column and then add up the overall total.
5
Evaluate
Discuss with students why carbon footprints can be controversial and what could be the limitations on their calculations? Students can write an article about their findings for your school Newsletter.
