  1. Accounts for primary material flows by branchesand material categories-methodological concepts, results and applications- Paper presented at the 9th London Group Meeting in Copenhagen 22 – 24 September 2004

  2. Accounts for primary material flows by branchesand material categories-methodological concepts, results and applications- • 1. Introduction • 2. Methodological concept of German primary material flow accounts • 3. Results • 4. Conclusion and Outlook

  3. Accounts for primary material flows by branchesand material categories-methodological concepts, results and applications- • Political background: • Initiative of the OECD environmental ministers and the OECD council for establishing an OECD-wide system of comparable international material flow accounts • National Strategy on Sustainable Development

  4. Accounts for primary material flows by branchesand material categories-methodological concepts, results and applications- • Aim of this project: • Providing disaggregated accounting data for the headline indicator of the National Strategy on Sustainable Development on “raw material productivity”

  5. The German system of physical flow accounts Economy wide material flow accounts Input of raw material and outputs of air emissions, waste and other residuals to the environment by type of material [t] Energy flow accounts Supply and use of energy by economic activities (NAMEA-type breakdown) and by type of energy carrier [Petajoules] Primary material flow accounts Supply and use of raw materials by economic activities and type of material [t] Monetary Input-Output tables (MIOT) Supply and use of products, monetary integration table by economic branches (NAMEA-type breakdown) [Euro] Physical Input-Output tables (PIOT) Extraction from/ emissions to the environment, material integration table by economic activities (NAMEA-type breakdown) and type of material [t] Water flow accounts Supply and use of water and waste water, water flows within the economy by economic activities and type ofwater [m3] Waste flow accounts Supply of waste by economic activities and type of waste [t] Air emission accounts Output of air emissions to the environment by economic activities and type of air emission [t] Regional accounts (Breakdown by Federal States), Flow accounts (economy wide, NAMEA-type) for material, energy, air emissions and water Other NAMEA-type accounts Built-up and traffic area, transport (e.g. person-kilometres, tonnes-kilometres), environmental taxes, environmental expenditure

  6. Methodological concept: • Supply tables • Domestic extraction of raw • materials by type of raw • material • and the imported products • by homogeneous product • groups • (= primary material) • Use tables • Use of primary products • by homogeneous • production branches and • by private households.

  7. Supply tables Sand is extracted by primary production branch “Other mining and quarrying” Methodological concept:Example: Sand (domestic extraction) • Use tables • Sand is used by branches • “Other non-metallic mineral products”, • “Glass and glass products”, • “Site preparation work, structural and civil engineering work” and • “Chemical products”

  8. Abiotic primary material 1995 - 2001 mn t Domestic extraction Imports 1.600 1 454 1 419 1 428 1 410 1 416 1 393 1 341 1.400 395 406 413 413 441 1.200 431 428 1.000 800 600 1 059 1 022 1 006 1 003 969 962 913 400 200 0 1995 1996 1997 1998 1999 2000 2001

  9. Abiotic primary products by material categories Shares 2001 in % Change 2001 to 1995 in 1 000 t Energy carriers -43 114 and their 2.2 products 30 481 16.5 Energy carriers Metal ores 338 and their and their products products total -4 869 14.9 1 341 mn Other imported 51.5 t 11 620 abiotic products 3.1 Other mineral -103 289 Metal ores and raw materials 11.8 their products and their -4 177 Other mineral products Other imported raw materials abiotic products -100 000 -50 000 0 50 000 and their products Domestic extraction Imports

  10. Use of abiotic primary products by branches 2001 % Agriculture, hunting, forestry, fishing 1.2% 7.6 Mining of coal; extraction of peat 0.9% Branches, Other mining and quarrying total Manuf. of food prod. and beverages 1.4 % 19.1 Manuf. of chemicals a. chem. prod. 1.8 % 97.3% Manuf. of other non-metal. mineral products total 5.8 Manufacture of metals 1) 1 183 thereof: mn t 16.7 Electricity, gas, steam and hot water supply Construction 17.6 2.7% 8.2 Consumption Other manufacturing of private Services 5.7 households 97.3 % Branches, total 1) without not classified imported products (157 mn t)

  11. Decomposition analysis • Breakdown of the development of use of primary products into the 3 factors: • - economic growth, • - structural development and • - intensity of use of primary products by branches.

  12. Conclusion: • PMFA data can be used for various analytical purposes: • - Analysis of use of primary material in a breakdown by individual economic branches and by types of material • - Compilation of eco-efficiency indicators (e.g. use of primary product per unit gross value added) • - Analysis with decomposition analyses • Advantage: Compilation of PMFA data is quite easy and offers lots of analytical possibilities

  13. Outlook: • Future work to be done is: • - Completing the module by calculating also use tables for biotic primary products like wood and agricultural products • - Calculation of indirect effects by combining physical data with monetary input-output tables, e.g. for estimating raw material equivalents for imports and exports.
