car maintainance especially the engine, and tire pressure and condition• 53 We have tried to include the most common modes of transport to school across the globe - but we have probably missed some! Some mistakes might also be made when calculating distance or entering the data.
| We chose to make the CO 2nnect calculator relatively simple so that pupils could spend more time learning about their local transport systems and working with others to find sustainable solutions | For example, the amount of CO 2 emitted by a car using petrol will depend on many things:• The multipliers assume a certain average number of passengers in each mode of transport |
|---|---|
| There will always be some error in these measurements depending on the method used, and the distances are rounded up or down to the nearest kilometer | For example, if you ride a big bus that is almost empty, or extremely full, the multipliers might not be very accurate for your trip to school |
The same would be true for other methods of motorized transport.
