Consumption of hard coal: documentation of statistics
The documentation of the statistics describes how the statistics were compiled and what methods were used in the compilation. The data help interpret the figures of the statistics and evaluate their reliability and comparability. The quality report is based on the EU's SIMS model. The documentation also contains change releases describing changes in the statistics and possible specifying methodological descriptions.

Concepts and definitions (SIMS 3.4)
12-month moving total
Total for the latest twelve months. For example, the 12-month moving total for March is obtained by adding up data from the beginning of the previous year's April until the end of the current's year's March. Respectively, the total for April is obtained by adding up data from the beginning of the previous year's May until the end of the current year's April. Thus, the difference between the 12-month moving totals of April and March gives the difference between the previous year's and the current year's data for April.
Charcoal
Charcoal is a solid fossil fuel with an effective thermal value of more than 24MJ/kg in ashless substance. Coal is mainly graded according to the amount of volatile matter it contains and its thermal value. Metallurgical coal and coke produced from it are not regarded as charcoal.
Fossil fuels
Fossil fuels refer to fuels that have been formed of biomass and stored underground millions of years ago. Fossil fuels include coal, lignite, natural gas and fuel oils refined from crude oil. In international classifications peat is often classified as fossil fuel, although it is a clearly younger fuel than them.
Petajoule
Petajoule (PJ) is a unit of energy used for expressing the energy contents of fuels and other energy sources. 1 PJ = 1,000 TJ; 1 TJ = 0.278 GWh
