3.1. Data description

The European Union (EU) as a party to the Convention on Long-range Transboundary Air Pollution (LRTAP Convention) reports annually its air pollution inventory for the year t-2 and within the area covered by its Member States. Under the Convention, parties are obliged to report emissions data for numerous air pollutants.

This dataset includes data on 6 air pollutants: sulphur oxides (SOx), ammonia (NH3), nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), particulate matters (PM10, PM2.5), as reported to the European Environment Agency (EEA). The EU inventory is fully consistent with national air pollution inventories compiled by the EU Member States.

Note that Eurostat is not the producer of these data, only re-publishes them. 

Remarks:

(1) Data for CZ, PT, EL and EU 28 contain incosistencies (sum of components does not equal to total)

(2) PM2.5 and PM10 time series for EU Member States and EU 28 aggregates start from the year 2000.

3.2. Classification system

The dataset has five dimensions:

1) Air pollutant (AI): 6 air pollutants (SOx, NOx, NH3, NMVOC, PM10, PM2.5)

2) Geopolitical entity (GEO): EU Member States, EFTA Countries, Candidate Countries

3) Source sector for air emissions (AIRSECT): Sectors are classified according to the Nomenclature for Reporting (NFR 14) under the LRTAP Convention. To simplify the use of the data for assessment NFR 14 sectors are converted into a simpler sector format (EEA sectors). The EEA sectors represent an aggregation of the cca. 100 NFR source categories into 9 aggregated sectors. Details of the mapping used to convert NFR 14 to the aggregated EEA sectors is provided in Annex I to the Air pollutant emissions data viewer Manual.

4) Period of time (TIME): Data are annual

5) Unit (UNIT): The air pollutants are measured in tonnes

6. Institutional Mandate Top
6.1. Institutional Mandate - legal acts and other agreements

The Convention on Long-range Transboundary Air Pollution was the first international legally binding instrument to deal with problems of air pollution on a broad regional basis. It was signed in 1979 and entered into force in 1983. It has since been extended by eight specific protocols.

Directive 2001/81/EC of the European Parliament and the Council on National Emission Ceilings for certain pollutants (NEC Directive) sets upper limits for each Member State for the certain pollutants responsible for acidification, eutrophication and ground-level ozone pollution.

Within the EU inventory system, the European Environment Agency and its European Topic Centre on Air Pollution and Climate Change Mitigation are responsible for the annual compilation of the EU inventory.

6.2. Institutional Mandate - data sharing

Not applicable


7. Confidentiality Top
7.1. Confidentiality - policy

Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society.

7.2. Confidentiality - data treatment

See point 7.1


8. Release policy Top
8.1. Release calendar

Data are not bound by an advance release calendar.

The EEA publishes the validated air pollution inventory data in July. Eurostat re-publishes the data shortly after.

8.2. Release calendar access

Not applicable

8.3. Release policy - user access

In line with the Community legal framework and the European Statistics Code of Practice Eurostat disseminates European statistics on Eurostat's website (see item 10 - 'Accessibility and clarity') respecting professional independence and in an objective, professional and transparent manner in which all users are treated equitably. The detailed arrangements are governed by the Eurostat protocol on impartial access to Eurostat data for users.
