In Ecomaths, Stefan Gates explores reducing car use by comparing a journey in a taxi and pedalling a rickshaw to Bristol train station. On the rickshaw his passenger is cycle expert, Ian Tsang, who directs him to the first cycle path in England from Bath to Bristol that has up to 3000 people using it each day. He then sees a brand new cyclepath being built and meets project manager, Francis Mann. He explains the carbon cost of building the new cyclepath and gives Stefan the figures for carbon savings when someone goes by bike instead of by car. Stefan and Ian use the information to calculate how long it will take to repay the carbon cost based on how many people change from car to bike – after that it’s all carbon saving. Stefan then visits Chester Park Primary School, joining students who are collecting data and calculating the percentage of people who walk, cycle or come by car to the school. They compare their figures with the Bristol City Council's figures to see if the Bike-it scheme at the school is working.
