Energy efficiency and energy consumption in the transport sector Energy efficiency progress (Figure 1) is measured from the ODEX indicator. This index aggregates the unit consumption trends for each transport mode in a single indicator for the whole sector. It is calculated at the level of 8 modes or vehicle types: cars, trucks, light vehicles, motorcycles, buses, total air transport, rail, and water transport. For cars, 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/ton-km for transport of goods by rail and water, toe per vehicle for motorcycles and buses.  The variation of the weighted index of the unit consumption by mode between t-1 and t is defined as follows It /It -1= 1/( It -1/It) with : energy share EC i  (consumption of each mode i   in total transport consumption); unit consumption index UC i (ratio : consumption related to traffic or specific consumption in l/100 km for cars); t refers the current year, t-1 to the previous year.   The value at year t can be derived from the value at the previous year by reversing the calculation:   It /It -1= 1/( It -1/It)   ODEX is set at 100 for a reference year and successive values are then derived for each year t by the value of ODEX at year t-1 multiplied by It /It -1. The energy consumption variation of passenger transport in Figure 4 is broken down into 3 explanatory effects: activity effect (increase in traffic), modal shift effect (from private transport to public transport modes) and energy savings (change in specific consumption per unit of traffic). A positive “modal shift effect” means that the share of public passenger transport in passenger traffic is decreasing (shift from public transport to cars)  or the road in total freight traffic is increasing (shift from rail-water to road): this offsets energy savings. CO2 emissions for total transport are split into 2 explanatory effects (Figure 6): an activity effect due to an increase in traffic of passengers and freight, CO2 savings due to the reduction in the specific emissions of vehicles per unit of traffic.

Energy efficiency and energy consumption in the household sector Household energy consumption, covers all energy consumed in households for space heating, water heating, cooking and electricity.    Figures are reported either aggregated or disaggregated according to the end use categories named and as a total figure or per dwelling or m 2 of housing area. Climate fluctuates from one year to another. When the data is flagged as climate corrected, the data is normalized to reflect similar weather conditions. Consumption in useful energy per degree-day corrects for difference in heating equipment efficiency (which varies according to the fuel  uses) and climate.   Energy efficiency indices (ODEX) can be defined as a ratio between the actual energy consumption of the sector in year t and the sum of the implied energy consumption from each underlying sub-sector/ end use in year t (based on the unit consumption of the sub-sector with a moving reference year. The evaluation of energy savings in household is carried out at the level of three end uses (heating, water heating and cooking) and five large appliances (refrigerators, freezers, washing machines, dishwashers and TVs). For each end use, the following indicators are used to measure efficiency progress: heating — unit consumption per m 2 per dwelling equivalent to central heating at normal climate; water heating — unit consumption per dwelling with water heating; and cooking — unit consumption per dwelling. The average energy consumption per m 2 per dwelling equivalent to central heating is used to leave out the impact of the diffusion of central heating. The effect of (heating) behaviour was estimated by assuming that technical progress cannot be reversed Household CO 2 -emissions covers the direct CO 2 emitted by fuel combustion.

CO2 intensity of electricity and heat generation Annual emissions of CO 2 in UNFCCC reporting format (In Mt = million tonnes). For CO 2 only, the (national) totals do not include emissions from biomass burning or emissions or removals from land-use change and forestry (LULUCF – CFR 5). The energy sector (CFR 1) is responsible for energy-related emissions, such as those arising from fuel combustion activities and fugitive emissions from fuels. Fuel combustion activities include: energy industries, manufacturing industries and construction, transport, other sectors and other stationary or mobile emissions from fuel combustion. Fugitive emissions from fuels include: solid fuels and oil and natural gas.

Emissions from public electricity and heat production - explanatory indicators (ENER 009) Historical emissions of CO2, NOX and SO2 from the common reporting format category 1A1a Public electricity and heat production. Output from public thermal power stations covers gross electricity generation and any heat also produced by public thermal power stations. Public thermal power stations generate electricity and/or heat for sale to third parties, as their primary activity. They may be privately or publicly owned. The gross electricity generation is measured at the outlet of the main transformers, i.e. the consumption of electricity in the plant auxiliaries and in transformers is included.

A positive “modal shift effect” means that the share of public passenger transport in passenger traffic is decreasing (shift from public transport to cars)  or the road in total freight traffic is increasing (shift from rail-water to road): this offsets energy savings. CO2 emissions for total transport are split into 2 explanatory effects (Figure 7): an activity effect due to an increase in traffic of passengers and freight, CO2 savings due to the reduction in the specific emissions of vehicles per unit of traffic.
