CA4S is an innovative citizen science and engagement project aimed to educate pupils and parents about the causes and effects of air pollution on health and how to reduce their contribution and exposure to air pollution through their travel aspirations. We did this through engagement of practical teachings, mapping and taking action.

Cycling was found to be the favoured option for pupils, however, there are many barriers such as safety, not owning a bike and inability due to younger siblings. 68.4% of pupils stated that safety was their biggest consideration for mode of transport to school. Additionally public transport was seen as “dirty”, expensive and less safe than a car as well as being perceived to making you late. Following the project there was an increase in desire of action to be taken for more sustainable travel. Multiple ideas such as car sharing and walking buses are being put forward and implemented.
