  1. Requirements for energy statistics for the development of hybrid/NAMEA data systems Julie L. Hass, Statistics Norway London Group on Environmental-Economic Accounting Session 5: Issues related to Chapters 3 and 4 Johannesburg, South Africa, 26-30 March 2007

  2. Environment and economy: pieces into a picture

  3. Requirements for hybrid/NAMEA accounts Consistent with the national accounts before linking... 3 system requirements for the energy data: • Same definitions and boundaries as the national accounts • Same groupings of institutional units as the national accounts and consistency over time • Attributing residuals/energy use to appropriate institutional units

  4. Requirements for hybrid/NAMEA accounts Residence principle • An institutional unit is said to be resident within the economic territory of a country when it maintains the centre of economic interest in that territory – that is, when it engages, or intends to engage, in economic activities or transactions on a significant scale either indefinitely or over a long period of time, usually interpreted as one year. (SNA-1993) • Attributing energy use to appropriate institutional units • Need to have this by industry and by energy carrier • Increases the uncertainty when information is broken down into such detailed institutional units

  5. Transportation in hybrid/NAMEA accounts is a big challenge

  6. Challenges of establishing NAMEA-energy at Statistics Norway • Foundation already established in energy accounts and statistical data bases • Needs reorganization of data into NAMEA-style supply and use table • Difficult to check NAMEA totals vs. energy accounts totals • Large statistical discrepancies– do not know if these are on the supply or use side Statistical discrepancies: • Petrol 25 per cent of intermediate consumption and household use • Coke 23 per cent, natural gas 19 per cent and other gases and LNG approximately 80 per cent • Quality of NAMEA-energy data becomes questionable since so much energy consumption cannot be attributed to institutional units

  7. Issues to consider • What are energy accounts/ NAMEA/hybrid accounts? • Are subsoil asset accounts for energy part of “energy accounts”? • Consistency with official statistics (energy balances) and bridge tables • Methodological issues: harmonisation of classifications, energy conversion factors, integration of various data sources • Treatment of statistical discrepancies • Treatment of import/export data • Treatment of renewable energy • Link with air emissions data and the need for emissions related energy use • Indicators • How to treat inconsistencies between energy statistics and National accounts?
