For the transport sector, the ODEX is calculated out at the level of 8 modes or vehicle types: cars, trucks, light vehicles, motorcycles, buses, total air transport, rail, and water transport. The overall energy efficiency index aggregates the trends for each transport mode in a single indicator for the whole sector |
For cars, the energy efficiency is measured by the specific consumption, expressed in litre/100km |
|
|
|
|
|
|
|
For the transport of goods (trucks and light vehicles), the unit consumption per ton-km is used, as the main activity is to move goods |
|
|
|
|
For other modes of transport various indicators of unit consumption are used, taking for each mode the most relevant indicator given the statistics available |
|
|
|
- toe/passenger for air |
|
|
|
|
|
|
|
|
|
|
|
|
- goe/pass-km for passenger rail |
|
|
|
|
|
|
|
|
|
|
|
|
- goe/tkm for transport of goods by rail and water |
|
|
|
|
|
|
|
|
|
|
- toe per vehicle for motorcycles and buses |

For countries with a limited data coverage, the ODEX is calculated for road, rail, water and air using aggregate unit consumption for these modes. |
|
|
|
For rail, water and air, the calculation is based on unit consumption per ton-km or passenger-km. |
|
|
|
|
|
|
|
For road, the indicator used is the fuel consumption of road vehicles per equivalent car relates the total consumption of road transport to a fictitious stock of all road vehicles, measured in terms of a number of equivalent cars. |
The data required are the following: |
|
|
|
|
|
|
|
|
|
|
|
- The total energy consumption of road transport. |
|
|
|
|
|
|
|
|
|
|
- The stock of road vehicles by type |
|
|
|
|
|
|
|
|
|
|
|
- Coefficients reflecting the difference in average yearly consumption between each type of vehicle and a car (1 truck and light vehicle = 4 cars equivalent , 1 bus = 15 car equivalent and 1 motorcycle = 0.15 car equivalent) |
