In the Business-as-Usual Scenario the most dominant modes (road and air) are also the ones with the highest specific consumption (except for the ship which has a huge specific consumption but with a lower level of usage). The most fuel efficient mode is the train.

 

In the Efficiency Scenario cars and motorcycles can reduce their specific consumption and become one of the most efficient along with the train thanks to electrification and the increase in the load factor, which a smart transport system offers.

 

One of the Efficiency Scenario's important strategies to facilitate the rapid advance towards a more sustainable system is a change in the approach towards these mobility modes –dominant and poorly efficient at present– and lead them into efficiency.

The most problematic mode of transport that still remains is air travel; therefore, a key objective is to limit its use to a minimum and shift as many journeys as possible to rail.
