Domestic Extraction (DE) The raw materials from the national natural environment, such as fish, oil and stone, which are inputted into the same economy.
Domestic Material Inputs (DMI) The mass of materials which enter the economy including domestically extracted and imported material.
Domestic Material Consumption (DMC) The mass of material used in an economy including imports and exports based on the physical mass of the materials traded. The mass of raw material required to produce traded materials are not included.
Physical Trade Balance (PTB) Imports minus exports. An economy has a trade deficit if imports are less than export, and a trade surplus if imports are greater than exports.
Imports/Exports Raw Material Equivalents (RME) The trade of goods and products including the raw material extraction required for their production. The Scottish MFA uses RME factors developed by the EU.
Raw Material Input (RMI) The mass of materials, including the raw materials required to make traded goods and products, which enter the economy including domestically extracted and imported material.
Raw Material Consumption (RMC) The mass of material used in an economy including imports and exports including the raw materials extracted to produce the traded materials. The asymmetry between domestic extraction and physical trade means a country could significantly reduce its DMC without reducing worldwide demand for material resources. RMC allows for a more complete measurement of material consumption.
Physical Trade Balance RME (PTB-RME) Imports minus exports including raw material equivalents.
