Transport and Climate Change

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. 

What You Can Do 

• Cycle or walk: where possible avoid using the car for short trips. Walking and cycling are good for the environment and your health

• Use public transport where possible: many trips can be taken by bus or train

• Investigate whether car-pooling or 'park and stride' are possible in your area

• Consider holiday destinations closer to home or travel by train or boat where possible, this will reduce the number of flights you take

• For car drivers, ensuring the tyres are at the correct pressure, and avoiding driving too fast, all improve fuel efficiency. If the car is to be replaced, the fuel economy of the new car could be taken into account.
