In brief

Each year, on request from the French Environment Ministry, CITEPA produces a large number of emissions inventories in formats that are specific to each institutional framework (United Nations, European Commission).

The reports (UNFCCC, UNECE/NEC, LCPs, NAMEA, etc.) cover different fields in terms of substances, emission sources and geographical area. They are compiled to a fixed format defined by international bodies, and therefore not easily interpreted by non-specialists.

CITEPA also produces data on emissions released well before the periods covered by these reports (published since 1966) and is in possession of analysis results on emission trends over time and by sector of activity.

In order to make all of its air emissions data available in an easily understandable form, CITEPA, with the support of the French Environment Ministry, developed a specific inventory format in the mid-1990s, known since 1999 as the SECTEN format (Economic sectors and energy). This report is based on the same data as those used to compile the official national inventories (cf. reporting frameworks mentioned above), but it groups them together, covers longer periods of time and presents the data in a more user-friendly format.

The SECTEN report is produced under the national system of air emissions inventories and audits (SNIEBA). It is updated each year during the year, contains over 300 pages and provides information organised into several main categories.

SECTEN data figures

The data of the SECTEN inventory (tables and graphs), without analysis, are downloadable free of charge on this page. These data are public (financed by the Environment Ministry).

CITEPA cannot accept responsibility for the use and interpretation of these unprocessed data.

Geographic scope

SECTEN data concern mainland France but some additional files also present data concerning greenhouse gases in the format of the KYOTO scope (mainland France + overseas included in European union). The following chart shows the various geographical scopes of the emission inventories.

Temporal scope

The results cover the 1990-2017 period and estimations for the year 2018 (preliminary estimations) are sometimes provided. Furthermore, for some substances, data has been reported since 1980, in particular those covered by the various Protocols adopted under the Convention on Long-range Transboundary Air Pollution and since 1960 for substances traditionally studied by CITEPA (SO2, NOx, CO2, CO).



In total, data are reported for 30 different substances (cf. table below) and various indicators including those on acidification and the greenhouse effect. Fluorinated gas, NMVOC and PAH speciations are also available.

Acidification, eutrophication, photochemical pollution SO2, NOx, NH3, NMVOC, CO
Enhancing greenhouse effect (indirect greenhouse gases already reported under the issue acidification and photochemical pollution are not mentioned here) CO2, CH4, N2O, HFCs, PFCs, SF6, NF3
Contamination by heavy metals As, Cd, Cr, Cu, Hg, Ni, Pb, Se, Zn
Contamination by persistent organic pollutants Dioxin/furans (PCDD-F), PAHs*, PCB, HCB
Particulate matter Total suspended particules (TSP), PM10, PM2,5, PM1,0, Black carbon

 * total of the 4 PAHs: benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene et indeno(1,2,3-cd)pyrene
