3.4. Statistical concepts and definitions Statistical characteristics of statistical observations.

Binding of the greenhouse gases – anthropogenic induced sequestration of greenhouse gases in ecosystem (e.g. during the photosynthesis or chemical reactions).

Carbon dioxide equivalent – the amount of CO₂ that would have the same global warming potential as the given amount of greenhouse gas.

Emission of carbon dioxide – total anthropogenic carbon dioxide (CO₂) emission from the sectors of energy, industrial processes, solvent and other product use, agriculture, land use change and forestry, and waste (as defined by IPCC). Natural emission is not accounted for in this indicator.

Emission of methane – total anthropogenic methane (CH₄) emission from the sectors of energy, industrial processes, solvent and other product use, agriculture, land use change and forestry, and waste (as defined by IPCC). Natural emission is not accounted for in this indicator.

Emission of nitrous oxide – total anthropogenic nitrous oxide (N₂O) emission from the sectors of energy, industrial processes, solvent and other product use, agriculture, land use change and forestry, and waste (as defined by the IPCC). Natural emission is not accounted for in this indicator.

Greenhouse gases – gases that bind the reflecting infrared radiation and cause the rising of the global atmospheric temperature. The main greenhouse gases were carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulphur hexafluoride (SF₆).

Greenhouse gas emission – anthropogenic emission of greenhouse gas which is usually expressed in CO₂ equivalents.

11. Quality management Systems and frameworks in place within an organisation to manage the quality of statistical products and processes.

11.1. Quality assurance All systematic activities implemented that can be demonstrated to provide confidence that the processes will fulfil the requirements for the statistical output.

To assure the quality of processes and products, Statistics Estonia applies the EFQM Excellence Model, EU Statistics Code of Practice and the ESS Quality Assurance Framework (QAF). Statistics Estonia is also guided by the requirements provided for in § 7. „Principles and quality criteria of producing official statistics” of the Official Statistics Act.

11.2. Quality assessment Overall assessment of data quality, based on standard quality criteria.

Statistics Estonia performs all statistical activities according to an international model (Generic Statistical Business Process Model – GSBPM). According to the GSBPM, the final phase of statistical activities is overall evaluation using information gathered in each phase or sub-process (this information includes, among other things, feedback from users, process metadata, system metrics and suggestions from employees). This information is used to prepare the evaluation report which outlines all the quality problems related to the specific statistical activity and serves as input for improvement actions.

12.1. User needs Description of users and their respective needs with respect to the statistical data.

Users’ suggestions and information about taking them into account are available on the SE website https://www.stat.ee/statistikatood.

12.2. User satisfaction Measures to determine user satisfaction.

Since 1996 Statistics Estonia conducts reputation surveys and user surveys.

All results are available on the website https://www.stat.ee/user-surveys.

12.3. Completeness The extent to which all statistics that are needed are available.
