In FIN-MFA accounting system domestic flow accounts are divided by sectors <strong>and</strong> they contain boththe direct as well as hidden flows. Domestic hidden flows are either compiled from existing statistics(e.g. mining) or produced by using relevant multipliers (earth materials, forest <strong>and</strong> forest by-products,agriculture). By volume these domestic flows are by the far the most important part <strong>of</strong> FIN-MFA. Themost work however, has been done in collecting material flows <strong>of</strong> external trade. As Finl<strong>and</strong> is typicallydepended on large-scale external trade, especially on exporting natural resource intensive commodities,are these accounts important part <strong>of</strong> FIN-MFA workbook. Imported <strong>and</strong> exported hidden flows aresolely produced by using relevant multipliers. In FIN-MFA accounting system the economy-wide MFAmain aggregates are calculated automatically by using the above mentioned different material flows.These indicators describe different environmental impacts <strong>and</strong> they are needed in the subsequent MFAanalysis <strong>and</strong> for policy making.3. Economy-wide MFA aggregate indicatorsMFA aggregate indicators can be used as proxies <strong>of</strong> environmental effects <strong>of</strong> economic activities orhuman-caused environmental burden. However, material flow indicators do not directly tell about theactual environmental impacts that are caused to earth. As MFA-approach does not classify theharmfulness <strong>of</strong> specific material flows, they can not the scope <strong>of</strong> the wide variety <strong>of</strong> environmentaleffects caused by different material flows. Thus, small material flows that have large environmentaleffects can easily be neglected in these weight-based indicators. The focus on reduction <strong>of</strong> aggregatedresource use is thus necessary, but not sufficient, precondition for achieving environmentalsustainability. (Giljum et al. 2006.)Economy-wide MFA indicators indicate the overall the metabolic performance <strong>of</strong> national economiesthey sum all materials required by an economy in metric tonnes. They <strong>development</strong>s <strong>of</strong> certainimportant <strong>trends</strong> related to economic activities <strong>and</strong> the environment. Direct Material Input (DMI),which is the aggregated measure <strong>of</strong> the natural resource commodities that enter an industrial economyfor further processing. The DMI includes all materials used for production; the natural resources neededfor energy production, auxiliary material production, infrastructures, transportation, factories, etc., in aproduct line. From environmental policy point <strong>of</strong> view DMI represents the proxy <strong>of</strong> potentialenvironmental pressures caused the welfare creation processes <strong>of</strong> a society. Direct MaterialConsumption (DMC) accounts for all materials used up by a country. Thus, in calculation <strong>of</strong> DMCexports subtracted from DMI indicator. DMC is most comparable MFA indicator to GDP. Fromenvironmental perspective DMC can be regarded as a proxy <strong>of</strong> potential environmental pressuresassociated to the disposal <strong>of</strong> residual materials to the domestic environment.Total Material Requirement (TMR) counts all material inputs required by a national economy.Beside direct flows TMR also includes the hidden or indirect material flows (or ecological rucksacks <strong>of</strong>direct flows). These hidden flows (HF) are material flows or relocations <strong>of</strong> materials which are caused bythe utilisation <strong>of</strong> Direct Material Inputs but which never enter the economy. (Hinterberger et al 1997, 10;Adriaanse et al. 1997, 7-8). Thus TMR measures the total use <strong>of</strong> natural resources that a nationaleconomic activity requires. From economic perspective TMR is a measure <strong>of</strong> the physical basis <strong>of</strong> theeconomy, or the total primary resource requirements <strong>of</strong> all production activities <strong>of</strong> a national economy.TMR is a proxy for potential environmental pressures caused by resource extractions.
