Which statement(s) is (are) TRUE about emissions from transport?

Group of answer choices

To estimate the global environmental impact from transport, we need to know the total fuel volumes used but the fuel types used are irrelevant.

It is not only the vehicle characteristics but also human behaviour that influence the type or the extent of local externalities in road transport.

To tackle global externalities related to the use of transport fuel, the policy needs to deal with the precise location and the timing of the fuel use (emission).
