2. Introductory remarks
Initial work in the 1960s: industrial metabolism (Bob Ayres)
Economy-wide MFA started in early 1990s in Austria (IFF, Vienna), Japan (Environment Agency) and Germany (Wuppertal Institute and FSOG)
Eurostat Methodological Guide in 2001
Currently: many (supra-)national MFA studies including important contributions to further development of the methodology and identification of critical data issues
→ Where we are now
What is needed in the future: international/global harmonization and refined documentation of methodology, and maybe a practical guide and guidance for users.

3. The Focus: Economy-wide MFA
Basic reference: Eurostat Guide on economy-wide MFA:
(economy-wide) Material Flow Accounting, MFA
A monitoring system for national economies based on methodically organised accounts and denoting the total amounts of materials used in the economy. Material flow accounting enables monitoring of total consumption of natural resources and the associated indirect flows as well as calculation of indicators.
Material Flow Analysis, MFA
An evaluation method which assesses the efficiency of use of materials using information from material flow accounting. Material flow analysis helps to identify waste of natural resources and other materials in the economy which would otherwise go unnoticed in conventional economic monitoring systems.

6. Definition: DEU
Domestic extraction used (DEU) accounts for raw materials extracted or harvested on the economy‘s territory within a given period (one year).
Raw materials in this respect are those which enter the domestic economy for further processing or consumption.
Unused domestic extraction (→ UDE) associated with DEU is excluded. It may, however, be a source for direct material inputs contributing to DEU (e.g. soil excavated and reused in constructions).
DEU is one of the two main components of Direct (used) Material Inputs (DMI), the other one being Imports.
DMI comprises all materials (except water and air) that enter the economy for further use in production or consumption.

7. Main material groups: DEU
Fossil energy carriers (fossil fuels) → Non-renewables
Minerals → Non-renewables
Biomass → Renewables
NB:
The MIPS concept comprises 5 material groups:
- abiotic raw materials (DEU: fossils and minerals)
- biotic raw materials (DEU: biomass)
- Soil (Erosion as part of → UDE and → IF of imports/exports, memorandum item)
- Water (not part of economy-wide MFA, but of balancing items, → NAMEA, EU Headline indicator)
- Air (part of balancing items → NAS)

11. DEU: Biomass – conventional account
from Agriculture: harvest (statistics)
from Agriculture: by-product of harvest (statistics or estimates)
from Agriculture: grazing of livestock (statistics or estimates)

from fishing (marine, inland) – aquaculture?
from hunting
Other biomass (honey, mushrooms, etc.)

12. DEU: Biomass – conventional account
Eurostat Guide:
5.25 All (domestic) biomass is counted which is reported by agricultural harvest statistics, logging statistics, fishery statistics and hunting statistics. In addition, the input of biomass by grazing of animals can be taken from feedstuff statistics or can be estimated based on land use or nutrition balances of livestock. Feedstuff statistics will often also report on domestic biomass inputs of sugar and fodder-beet leaves, and of catch crops. Internationally, a great part of biomass input can be taken from the website of the Food and Agriculture Organization (FAO -

13. DEU: Biomass - supplement
from sustainable cultivation (eco-farming, eco-forestry, agro-forestry, etc.)
for food or other uses (energy, materials for manufacturing, other)
by intensity of land use (degrees refering to e.g. use of mineral fertilizers and pesticides, erosion risk, etc.)

14. DEU: Accounting conventions
Use for further processing or consumption (whether reported or not in official statistics: e.g. some feedstuffs, private or ancillary activities, small-size enterprises)
Reported actual (gross or fresh) weights, except for some special cases as follows. (Supplement dry weight accounts)
Crude ore or run-of-mine concept after Eurostat Guide:
5.12 … In this Guide it is recommended to base the accounts on the ‘run of mine’ concept and to always account for the crude ore (see also Isacsson et al. 2000). If primary data are only
available for concentrates, these should be converted back to the crude ore equivalent. Crude ore extracted should be considered a direct material input and part of DMI and DMC.

16. DEU: Accounting conventions
Standardized water contents after Eurostat Guide:
…For some special cases where reported data must be complemented by estimates (e.g. fodder plants taken up by grazing livestock) it is recommended to convert these into a weight that is equivalent to that of products typically reported in statistics so as to render reported and estimated data comparable. This involves using a ‘standardised water content’. For most bulk biomass materials (timber, cereals, hay) such a standardised water content will be around 15% of total product weight…

23. DEU: Accounting conventions
Standard physical conversion factors:
E.g. energetic units, weights, dimension, densities (e.g. in Ritthoff et al. 2002)
Variable conversion factors:
E.g. heat values of energy carriers (e.g. kJ per kg from energy statistics, examples in Ritthoff et al. 2002), densities of crude natural gases, other volume/weight ratios (e.g. wood, peat, soil, stones)

25. DEU: Data sources General rules:
- Prefer original national data sources to international or re-produced ones, and contact (national) experts in critical cases.
- Check for limits of reporting, perform plausibility checks for most critical items (green biomass, construction materials).
Data sources in general:
- Fossil fuels: Energy statistics or energy balances, NAMEA, (International: OECD-IEA)
- Minerals: Statistics of mining and quarrying industries; Statistics of Industrial Associations, (Inter-)National production statistics (USGS, UN, PRODCOM), Metal balances
- Biomass: Statistics of Agriculture, Forestry, Fishing, Hunting; Standardized feedstuff statistics (International: FAOSTAT), Supply-Use balances

26. DEU: Data sources: potential limitations
Basic statistical data may be wrong, misleading, incomplete and/or inconsistent over time and across countries (e.g. USGS, data for construction minerals and differentiation towards industrial minerals, fodder plants)
Official statistics do not report the total weight of materials but only specific contents (run-of-mine concept for metals)
Statistical data in time series reveal individual gaps or different references (e.g. USGS)
International statistics have to be used instead of specific national statistics (leading to many of the general problems)
Data required to account for material indicators are not available from statistics (uncertainties associated with estimates)

29. DEU: Requirements for further development
Domestic Extraction Used (DEU) requires further standardization with regards to classification of material categories and accounting conventions, in particular for green biomass (standardized water contents), and for minerals (crude ore or run-of-mine concept, diversion between industrial minerals and construction minerals). This should also lead to an unambiguous accounting for DEU versus Unused Domestic Extraction (→ UDE).
Further development of particular accounts (e.g. DEU construction minerals) to be formulated on empirical results and individual priority setting for improvement.
