Cars and other motor vehicles produce gases when they burn petrol or diesel. These include carbon dioxide (CO2), which contributes to global warming. Exhaust fumes also contain carbon monoxide and other toxic chemicals which are harmful to our planet and our health, causing breathing problems and even some cancers. When you are a passenger in a vehicle you can actually be exposed to 3 times more fumes than if you are walking or cycling.

Petrol and diesel are made from oil, which is a ‘fossil fuel’. There is only a limited amount left in the world, and it is getting harder to get it out from under the ground. (One of the reasons it is getting so expensive.) Perhaps in your lifetime there will be no more oil available, so scientists and engineers are busy looking for new ways to power vehicles – including solar, electricity, bio-fuels, hydrogen, even water!
