  1. Input-Output Analysisin the Environmental-Economic Accounting Šárka Buyny Project: Calculation of raw material equivalents

  2. Results • Calculation method • Evaluation and improvement potential

  3. Results • Calculation method • Evaluation and improvement potential

  4. Calculation method • input output analysis • life cycle analysis

  5. Calculation method • input output analysis • life cycle analysis - material flow tables - import coefficients - transport energy

  6. ore metal semi- finished products material flow tables 1.Step: Material flow tables Description of the first production processes,in physical units (tons)

  7. 2.Step: Input-output-analysis RME for semi-finished and finished products (incl. services) MFT allocation of MFT-products to the branches input-output -analysis

  8. 3.Step: Import coefficients for special products Raw material inputs (direct and indirect) of products, which are:- not produced in Germany- produced in Germany, but under different conditions- not included in the MFTs

  9. A B C D E A B C D E C C imports material intensity output Germany material intensity output abroad material intensity

  12. 4.Step: Transport energy Energy used for transport of imported (respectively exported) goods type of good type of transport transport model type of fossil fuel transported tons distance other determinants

  13. Results • Calculation method • Evaluation and improvement potential

  14. Results • Calculation method • Evaluation and improvement potential

  15. Evaluation and improvement potentials (1) • Hybrid approach • German input-output-tables • Consideration of the production conditions of import countries (energy mix, import coefficients) • Constant import coefficients for a whole time series • Aggregation problem of some raw material groups

  16. Evaluation and improvement potentials (2) • Capital formation • Waste and crap (metal and wood) • Recycling of glass and plastic: not included

  17. Thank you for your attention.
