3.1. Data description

Economy-wide material flow accounts (EW-MFA) provide an aggregate overview, in thousand tonnes per year, of the material flows into and out of an economy. EW-MFA cover solid, gaseous, and liquid materials, except for bulk flows of water and air. Like the system of national accounts, EW-MFA constitute a multi-purpose information system. The detailed material flows provide a rich empirical database for numerous analytical purposes. Further, EW-MFA are used to derive various material flow indicators.

The National Statistical Institute (NSI) sent to Eurostat on yearly basis the EW-MFA. The accounts comprise the following reporting tables:

  • Table A 'Domestic extraction (DE)': records material flows from the environment into the economy in a detailed breakdown by type of material
  • Table B 'Imports - total imports (intra- and extra-EU) and Table D 'Exports – total exports (intra- and extra-EU)': These physical trade tables record the imports and exports of products in thousand tonnes and grouped by materials.
  • Table F 'Domestic processed output (DPO)': records material flows from the economy to the domestic environment (e.g. emissions to air, water and soil)
  • Table G 'Balancing items': reports some memorandum items which are necessary to have the full material balance related to a national economy
  • Table H 'Indicators': presents the EW-MFA derived indicators which are automatically calculated from Table A to G
  • Table I 'Material flow accounts in raw material equivalents (RME)': records material flow accounts in raw material equivalents (MFA-RME). Some items are calculated automatically based on data reported in Table A and Table I
3.2. Classification system

EW-MFA record physical flows of materials broken down by type of flow and by type of material.

The type of flow dimension corresponds to the EW-MFA questionnaire reporting tables and derived indicators, namely:

  • domestic extraction (Table A)
  • physical imports (Table B)
  • physical exports (Table D)
  • domestic processed output (Table F)
  • balancing items (Table G)
  • direct material input (indicator)
  • domestic material consumption (indicator)
  • physical trade balance (indicator)

The breakdown by type of material employs a classification of materials. This EW-MFA classification of materials is hierarchical with main material flow categories (1-digit level). Each main category is further broken down, maximal down to 4-digit-level:

    1-digit: material category;

    2-digit: material class;

    3-digit: material group;

    4-digit: material sub-group.

 

3.3. Coverage - sector

The data refer to national economies as defined in the system of national accounts.

3.4. Statistical concepts and definitions

 

Conceptually economy-wide material flow accounts (EW-MFA) belong to the international system of environmental economic accounting (SEEA-Central Framework). Furthermore, EW-MFA is one of several physical modules of Eurostat's programme on European environmental economic accounts. It is covered by Regulation (EU) No. 691/2011 on European environmental economic accounts.

EW-MFA are closely related to concepts and definitions of national accounts. Most notably they follow the residence principle, i.e. they record material flows related to resident unit's activities, regardless where those occur geographically.

Further methodological guidelines are provided in various publications by Eurostat (see Eurostat website > Environment > Methodology, heading: 'Material flows and resource productivity').

For more detailed information please see also 3.1.

3.5. Statistical unit

Statistical units change according to the different data sources (e.g. agriculture, forestry and fishery statistics, production statistics, geological surveys, energy statistics, foreign trade statistics etc.) which EW-MFA are based on.

3.6. Statistical population

EW-MFA refer to the entire national economy of the reporting country (see also 3.3 'Coverage - sector')).

EW-MFA include all materials (excluding water and air) crossing the system boundary (between the environment and the economy) on the input side or on the output side. The economy is demarcated by the conventions of the national accounting system (resident units).

Material inputs to the economy cover extractions of natural resources (excluding water and air) from the natural environment and imports of material products (goods) from the rest of the world economy (ROW).

Material outputs are disposals of materials to the natural environment and exports of material products and waste to the ROW. Information on natural resources extracted and traded products is provided by different statistical units.

3.7. Reference area
The reference area is the economic territory as defined in SEEA CF 2012 and National Accounts (ESA). A unit is said to be a resident unit of a country when it has a centre of economic interest in the economic territory of that country, that is, when it engages for an extended period (1 year or more) in economic activities in that territory.
 
By following this residence principle, the the MFA records the purchases of fuels made abroad by Italian residents as imports, and purchases in Italy by units not resident in Italy as exports.

11. Quality management Top
11.1. Quality assurance

Since the 90s Istat adopted a systematic approach to ensure quality in both statistical information and service to the community. For this purpose, the Italian National Institute of Statistics has defined a quality policy providing itself with appropriate tools as well as management changes to carry it out.
Istat quality policy is aimed at the improvement of statistical outputs and processes through the development of appropriate methodologies and tools as well as an appropriate scientific and technical support, provided to the personnel directly involved in the production and dissemination of statistical information.
Istat quality policy is coherent with the European framework developed by Eurostat, taking up its main principles and definitions stated in the European Statistics Code of Practice and useful to ensure and strengthen the accountability and governance of the European Statistical System and of the National Statistical Systems.
For details: https://www.istat.it/en/organisation-and-activity/institutional-activities/quality-commitment

11.2. Quality management - assessment

Overall data quality is quite high for some items. It is medium or low for other. See "Accuracy" for details.


12. Relevance Top
12.1. Relevance - User Needs

Economy-wide material flow accounts (EW-MFA) provide a rich empirical database for numerous purposes. At international level the European Commission uses EW-MFA and derived indicators for developing and monitoring policies in domains such as circular economy, sustainable development, resource efficiency, sustainable consumption and production, and greening of other policy areas. The derived EW-MFA indicator domestic material consumption (DMC) is a headline indicator for the Europe 2020 resource efficiency initiative.

Domestic material consumption (DMC)  is one of the indicators chosen for representing environmental sustainability in the “Measuring Equitable and Sustainable Well-being” project, jointly promoted by Istat and the Constitutionally relevant body CNEL (Consiglio Nazionale Economia e Lavoro).

It also features in the national set of indicators for monitoring the Agenda 2030 goals (SDGs), in the same forms as in the international set.

12.2. Relevance - User Satisfaction

Istat is constantly interested in understanding who the users of the statistics it produces are, what the information needs are, whether they match production and if the statistics produced satisfy users. To this aim, together with the analysis of user requests received through the Web Contact Center service, tools for direct consultation were developed, such as the annual online survey of customer satisfaction and indirect tools such as analysis of accesses and of users' browsing paths on the web site.

12.3. Completeness

The system is complete and fully complying with relevant regulations/ guidelines.

12.3.1. Data completeness - rate

Will be calculated and provided by EUROSTAT.


13. Accuracy Top

EW-MFA constitute accounts and as such they are compiled from a variety of data sources. The majority of EW-MFA characteristics are based on statistical data sources. Some characteristics even need to be estimated because adequate statistical data sources do not exist.

13.1. Accuracy - overall

Please use Annex 3 for providing an assessment of the overall quality of the reported data.

No source is available for fish catch in inland waters.

Primary data on non-ligneous forest products are missing for most items and data on wood harvested has gotten poorer from year to year. Integrations to the data have been made based on national accounts estimates.

Data on non-energy minerals remain subject to high uncertainty, notwithstanding previous years' very substantial revision of the whole time series estimates.

The individual items under MF.2 and MF.3 are subject to uncertainties. This is due to lacking or poor, and often inconsistent, primary data, as well as to the lack of time for further analysis. The distribution of the MF.2+MF.3 total between the individual items needs further testing and possibly revision. Another test should concern the introduction of structural surveys on agriculture as a data source for crops.
Also several minor items of table A are subject to high uncertainty especially under the biomass heading. These are “MF.1.2.1.2 Other crop residues (sugar and fodder beet leaves, other)“, as it is not clear to what extent the dwindling quantities of sugar beet leaves are still used as fodder (sugar production is fading out in Italy and as a consequence all its related markets); “MF.1.3 Wood”; “MF.1.4.1 Wild fish catch “and “MF.1.4.3 Hunting and gathering” for the lack of sources reported above.

While some details may still need refinement, the quality of the estimates is in general kept at the level of the previous edition. We did not have to change any figure for years 1990-2021.

15.2.1.1. Comparability - over time detailed

Please use below table for explaining b)-flags (breaks in time series):

Year (of the break in series) Questionnaire table(s) MF-code(s) Reason for' break in time series'
 2008  B, D  MF.4, MF.5  

Estimates for all MF4 and MF.5 items in tables B and D for years 2008+ are coherent with PEFA estimates in TJ (a small uncertainty remains because a few products present in Eurostat-format Energy Balances and included in PEFA have not been connected to any specific item in the Combined Nomenclature, through which the PEFA-MFA cross-classification goes. These products should be included “somewhere” in trade data, though). Data for the same items for the years before 2008 are estimated by extrapolation based on of the comparison between PEFA results and foreign trade statistics.

 2008  B, D   ‘Stage of Manufacturing’  The different methodology used to estimate the MF.4 and MF.5 items, for the years before 2008 and 2008+, also affects the estimation of these items.
