For a number of our indicators the energy savings calculated from the ODYSSEE database (top-down savings) or the MURE database (bottom-up savings) are important starting points. The top-down energy savings are calculated based on the unit consumption at the level of up to 30 sub-sectors or end-uses. Savings from international air transport and ETS sectors in industry are included as well. In industry and freight transport, savings may be negative for some years due to a deterioration of energy efficiency; this is due to capacity effects in industry and freight transport in times of economic recession. They are derived from the ODEX, an indicator that measures the energy efficiency progress by sector. For each sector, this index is calculated as a weighted average of subsectoral indices of energy efficiency progress. Such sub-sectors are branches of the sectors industry or service, end-uses for households or modes for transport.
The bottom-up savings provided by the MURE database originate from policy evaluation studies on a national level and National Energy Efficiency Plans (NEEAP) as well as Article 7 notifications published by each Member state. For the indicators in our framework we use, if suitable, both top-down and bottom-up energy savings, as they provide different but equally interesting perspectives.
