Justification for indicator selection

The indicator tracks progress made in energy efficiency and reducing the energy consumption in the industry sector in EU-27 countries. Reducing the energy consumption in the industry sector will have a positive impact on the environment due to reduced environmental pressures associated with the production and consumption of energy. The indicator is complementary to ENER 21.

Indicator definition

  • Specific consumption per tonne produced : Energy consumption divided by the physical production (for steel, cement , paper)
  • Energy efficiency index of industry (ODEX) is a weighted average of the specific consumption index of 10 manufacturing branches; the weight being the share of each branch in the sum of the energy consumption of these branches in year t and the sum of the implied energy consumption from each underlying industrial branches in year t (based on the unit consumption of the sub-sector with a moving reference year). The 10 branches considered in the calculation are: chemical, steel, non ferrous, cement, other non metallic, paper, food, machinery, transport equipment and textile. For steel, cement and paper, energy savings are calculated using specific consumption per tonne produced; for the other branches, the indicator used is the ratio on energy consumption related to production index.

    The variation of the weighted index of the unit consumption between t-1 and t is defined as follows:

    It -1/It = SUMi ECi,t *(UCi,t/UCi.t-1)

    with : energy share EC i  (consumption of each branch i   in total industry consumption);

    unit consumption index UC i (ratio : consumption related to production index or ratio : consumption related to physical production of steel, cement  and paper)

    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

    CO2 emissions from energy uses split between direct emissions and indirect emissions:

    • Direct emissions refer to emissions from the combustion of coal, gas and oil products (source: EEA inventories 2009)
    • Indirect emissions (or electricity related) refer to emissions in the power sector corresponding to the electricity consumption in the sector

    Indirect CO2 = E ind/E tot * CO2 ie

    with E : electricity consumption (ind for industry, tot for all sectors) (source ODYSSEE database);

    CO2 ie : CO2 emissions from public electricity and heat production ( source EEA, inventories 2009)

    • CO2 emissions from energy uses split between direct emissions and indirect emissions: Direct emissions refer to emissions from the combustion of coal, gas and oil products (source: EEA inventories 2009); Indirect emissions (or electricity related) refer to emissions in the power sector corresponding to the electricity consumption in the sector

    Geographical coverage:
    The Eurostat database covers all 27 EU member states plus Iceland, Norway, Switzerland, Croatia and Turkey. Odyssee database covers EU-27 plus Norway and Croatia. Not always data is available for all countries.

    Temporal coverage:
    1990-2007 with a focus on the period 1997/2008 for detailed analysis by country (due to data non available or reliable for new EU countries before 1996)

    Methodology and frequency of data collection:
    Data collected annually in the framework of the ODYSSEE MURE project

    Methodology of data manipulation:
    More information on ODYSSEE available on the website http://www.odyssee-indicators.org

    Change in industry final energy consumption per person: (final energy consumption per country2007 /population per country2007) / (final energy consumption per country1990 /population per country1990) – 1

    Methodology for gap filling

    •  Energy consumption : source Eurostat except for :
      - Wood (NCE 20): source Enerdata / IEA
      - Construction (NCE 45): source Enerdata / IEA
      - Machinery (NCE 28-32) and transport vehicles (NCE 34-35) [in Eurostat energy consumption for these 2 branches are given together]  for ODYSSEE this overall consumption has been split into 2 sub branches according to the disaggregation given in the Enerdata ‘ s database (coherent with IEA)
      - Other branches : in Eurostat this residual branch includes also construction , wood; for ODYSSEE energy consumption of this branch has been recalculated as total industry minus sum of the energy consumption of the branches
    • Energy intensive branches:

    - Cement :
    o physical production: sum of the production of the 27 countries (source Odyssee)
    o energy consumption : based on the energy consumption of 12 countries (10  EU-15 countries: uk, swe, esp, prt, nld, ita, grc, fra, rfa, bel) + Poland and Hungary (source Odyssee), which is extrapolated for EU-27, based on the  share of production these 12 countries in the total production of cement (consumption EU-27= consumption 12* (production EU-27/production 12)).

    - Paper
    o physical production for EU-27 is the sum of EU-27 countries (source Odyssee)
    o energy consumption : source Euro stat

    - Steel :
    o physical production for EU-27 is the sum of EU-27 countries (source IISI)
    o energy  consumption : source Eurostat

    Uncertainties

    Methodology uncertainty

    No uncertainty has been specified

    Data sets uncertainty

    Not all data is available for all countries. Availability for data on years earlier than 2008, is higher.
    Odyssee data is recently updated (October 2010)

    The reliability of total industry energy consumption and related CO2 emissions is reliable due to trustworthy statistics underlying it.

    Rationale uncertainty

    No uncertainty has been specified
