Prefer to walk, to take a bicycle or the tramway

The tramway uses 15 times less than a car in terms of CO² for short distances than the car or the motorcycle, which are more polluting and not good for your health.
For long distances, use the train or the car instead of an aeroplane, which is extremely high on kerosene consumption.

WeeDoo's suggestion:
Give a priority to common means of transport for most of your travel requirements.
