Why is the transport sector important?

Transportation is important for multiple reasons such as economic activity and mobility.

What else do we need to know to track efficiency in transports?

What is the split between passenger

transport and freight transport?

How much energy is spent in my country

to transport one passenger on a

distance of one kilometer?

Is it more intensive to travel in my

country – by bus, car or train?

How does it compare to other countries

in my region?

What can we learn from

energy efficiency indicators?

With additional data we can see where energy is used
