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 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:
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. |

17.1. Data revision - policy | |||
Data revision are done by data providers and SSB before publishing and reporting the statistics annually. |
|||
17.2. Data revision - practice | |||
Revisions in the 2021 EW-MFA questionnaire: Yes, we have reported revised figures for M.F..2.1, M.F.2.9, M.F.3.7 and M.F.3.8 for the period 2016-2019. Only change we have in these revised figures than previous one is that we now have reported also figures for another elements under MF.2. Which were hold back by data provider because of confidentiality. As you see the new reported figures under the segment are marked with confidentiality & second confidentiality footnotes. Though total sum for metal ores are same as earlier reported figures. So revision as such is not changing the total amount of domestic extraction of metal ores in Norway. Figures for MF.4.2.2 has been revised for the period 2007-2019. Revision in figures occured because a new production system for energy account and energy balance statistics was implemented in 2016–2018, and the revision of the production system was accompanied by an extensive review of methods. |

18.5.5. Fuel trade, residence adjustment | |||
For maritime transport in the Norwegian physical energy account figures, we use monetary figures for costs to international bunkering (purchased abroad) that we receive from the Division for National account, as a data source for marine gas oil and fuel/bunker oil purchased abroad. However, the figure from the National account is not split on different energy products (such as marine gas oils and other fuels). In addition, we have to divide this figure on the energy price to get the physical quantity. For international aviation, we receive data for energy purchased abroad from the airline companies in Norway, so this figure is more exact. For fuel used by tourists in Norway, we assume that foreign tourists in Norway purchases the same quantity of fuel that Norwegian tourists purchase abroad, so in practice, there is no correction; (these figures outweigh each other). |
|||
18.5.6. Significant problems | |||
International navigation is an economic activity that needs more quality control. |
