Transport and Climate Change
The transport sector contributes greatly to CO2 emissions. Emissions from this section have increased significantly, with the growth in private car use accounting for the majority of this increase. About 2.5kg of CO2 is released for every litre of fuel burned in a car engine. The most effective way of tackling this is to use the car less often. By walking, cycling, or taking the bus, we can reduce our transport-related emissions.
Air transport is one of the fastest growing sources of greenhouse gas emissions. Aviation is particularly problematic in terms of its climate impact. In addition to carbon dioxide, aircraft emit nitric oxides, sulphate and soot particles and water vapour in the form of condensation trails all of which contribute to climate change. A molecule of greenhouse gas is several times more powerful when emitted at altitude than at lower levels. A survey could give information on the distances and types of transport involved (car, bus, bike, walking) in teachers and students getting to school.
