Time coverage
The data are preliminary until the final annual consumption of hard coal is known. The data for the previous year are updated to final data in the release for the third or fourth quarter of the current year.

12-month moving totalExternal link
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.

Accuracy, reliability and timeliness
Overall accuracy
The data for the previous year are updated to final data in the release for the third or fourth quarter of the current year. Final annual consumption data are calculated based on several statistical data sources, which are also used in the annual release of the statistics on energy supply and consumption. Final consumption data on hard coal are benchmarked on the monthly level to correspond with these final data.

Sampling error

Measurement error
Non-response error
Processing error
Errors are corrected and the users are informed about them as quickly as possible. Statistics Finland informs about significant errors to the same extent and through the same channels as in the releasing of the original data.
Notations about corrections and their points of time are added to the corrected releases.
Comparability
Comparability - geographical
Comparability - over time
Coherence - cross domain
Emissions caused by energy production form a central part of the GHG inventory. The data of the statistics on consumption of hard coal are coherent with the GHG inventory concerning emissions caused by energy consumption of hard coal.
Coherence - sub-annual and annual statistics
Coherence - internal

Legal acts and other agreements
The compilation of statistics is guided by the Statistics Act. The Statistics Act contains provisions on collection of data, processing of data and the obligation to provide data. Besides the Statistics Act, the Data Protection Act and the Act on the Openness of Government Activities are applied to processing of data when producing statistics.
Statistics Finland compiles statistics in line with the EU’s regulations applicable to statistics, which steer the statistical agencies of all EU Member States.
Further information: Statistical legislationExternal link
The compilation of statistics is guided by the general act of the national statistical service, the Statistics Act (280/2004, amend. 361/2013). Only the necessary data that are not available from administrative data sources are collected from data suppliers. Index series are published so that no individual enterprise's data or development can be deduced from them.The statistics belong to the Official Statistics of Finland (OSF) and to the European Statistical system (ESS).
In Finland, the compilation of statistics is guided by the Statistics Act (280/2004). The obligation to provide data is statutory and based on the Statistics Act (280/2004, Section 14) according to which practitioners of trade are obliged to provide Statistics Finland with such data that are necessary for the compilation of statistics. The Regulation on energy statistics (2008/1099/EC), obliges Statistics Finland to report data, of which the statistics on production of electricity and heat are an important part, to the EU. The data produced by energy statistics are needed to monitor the measures of the Directive on energy efficiency (2012/27/EU) and the Directive on the promotion of the use of energy from renewable sources (2009/28/EC).
Statistics Finland is obliged to report energy statistics to the IEA, which is an organisation within the OECD framework.
Confidentiality - policy
The data protection of data collected for statistical purposes is guaranteed in accordance with the requirements of the Statistics Act (280/2004), the Act on the Openness of Government Activities (621/1999), the EU's General Data Protection Regulation (EU) 2016/679 and the Data Protection Act (1050/2018). The data materials are protected at all stages of processing with the necessary physical and technical solutions. Statistics Finland has compiled detailed directions and instructions for confidential processing of the data. Employees have access only to the data essential for their duties. The premises where unit-level data are processed are not accessible to outsiders. Members of the personnel have signed a pledge of secrecy upon entering the service. Violation of data protection is punishable.

Release policy
Statistics Finland publishes new statistical data at 8 am on weekdays in its web service. The release times of statistics are given in advance in the release calendar available in the web service. The data are public after they have been updated in the web service.

Data sharing

Accessibility and clarity
Statistical data are published as database tables in the StatFin database. The database is the primary publishing site of data, and new data are updated first there. When releasing statistical data, existing database tables can be updated with new data or completely new database tables can be published.
In addition to statistical data published in the StatFin database, a release on the key data is usually published in the web service. If the release contains data concerning several reference periods (e.g. monthly and annual data), a review bringing together these data is published in the web service. Database tables updated at the time of publication are listed both in the release and in the review. In some cases, statistical data can also be published as mere database releases in the StatFin database. No release or review is published in connection with these database releases.
Releases and database tables are published in three languages, in Finnish, Swedish and English. The language versions of releases may have more limited content than in Finnish.
Information about changes in the publication schedules of releases and database tables and about corrections are given as change releases in the web service.
The data of the statistics are released on predefined days on Statistics Finland's web pages on the home page of the statistics. The home page contains links to, for example, the description of the statistics, concepts and definitions as well as the free of charge statistical database tables (StatFin). Information on the topic is also available in the Energy table serviceExternal link.Micro-data access
Data revision - policy
Revisions – i.e. improvements in the accuracy of statistical data already published – are a normal feature of statistical production and result in improved quality of statistics. The principle is that statistical data are based on the best available data and information concerning the statistical phenomenon. On the other hand, the revisions are communicated as transparently as possible in advance. Advance communication ensures that the users can prepare for the data revisions.
The reason why data in statistical releases become revised is often caused by the data becoming supplemented. Then the new, revised statistical figure is based on a wider information basis and describes the phenomenon more accurately than before.
Revisions of statistical data may also be caused by the calculation method used, such as annual benchmarking or updating of weight structures. Changes of base years and used classifications may also cause revisions to data.

Quality assessment
Quality assurance
Quality management requires comprehensive guidance of activities. The quality management framework of the field of statistics is the European Statistics Code of Practice (CoP). The frameworks complement each other. The quality criteria of Official Statistics of Finland are also compatible with the European Statistics Code of Practice.

User access
Data are released to all users at the same time. Statistical data may only be handled at Statistics Finland and information on them may be given before release only by persons involved in the production of the statistics concerned or who need the data of the statistics concerned in their own work before the data are published.
