Pollutants and greenhouse gases concerned

The list of pollutants and greenhouse gases emitted by the manufacturing industry sector, covered by CITEPA, are presented in the table below:

Pollutants concerned Environnemental Effet/Impact
SO2, NOx, NMVOCs, CO, NH3 (small amount) Acidification, eutrophication, photochemical pollution
CO2, CH4, N2O (small amount), HFCs, PFCs, NF3, SF6 Enhanced of the greenhouse effect
As, Cd, Cr, Cu, Hg, Ni, Pb, Se, Zn Heavy metals contamination
Dioxins/furans (PCDD-F), PAHs*, PCB, HCB Persistant organic pollutants contamination
Total suspended particules (TSP), PM10, PM2,5, PM1,0, Black carbon (BC) (small amount) Particulate matter

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


Main emission sources and trends

The manufacturing industry, waste treatment and construction sector, usually called manufacturing industry, includes several activities, such as combustion sources (boilers and process furnaces of manufacturing industry), as well as, decarbonising sources and non-energy uses.

This sector is divided into several sub-sectors:

  • the chemical industry: organic/non-organic chemical industry and miscellaneous including the production of sulphuric, nitric, glyoxylic acids, ammonia, paint, etc.,
  • construction including construction sites and public works, asphalt concrete plants, etc.
  • Industrial and transport equipment: capital equipment, mechanical/electrical/electronic construction and transport equipment including electronic components, batteries manufacturing,
  • Food processing, beverage industry including, for example, bread/sugar and flour manufacturing,
  • ferrous metals including blast furnace charging, rolling mills, etc.,
  • non-ferrous metals: production of lead, zinc, aluminium, etc.,
  • non-metallic minerals and building materials: mainly the production of glass, cement, lime, etc.,
  • paper and board manufacture including, for example, paper pulp manufacturing, etc.,
  • waste treatment including the incineration of wastes (domestic and municipal, industrial and hospital, etc.).
  • other manufacturing industries: other industry and non-specified sectors including in particular, wood manufacturing, printing industry, leather tanning, etc.

The full list of sources considered for the « Manufacturing industry » sector is available on this website, on the SECTEN page, section « List of sectors and sub-sectors by SECTEN category », by uploading the associated file.

Emission trends data for the « Manufacturing industry » sector by sub-sectors are available and downloadable on this website, on the SECTEN inventory page, section « Sub-sector contribution by air pollutant and greenhouse gas ».

The SECTEN report, available free of charge only in online reading on this website for CITEPA members, provides a sector analysis for each pollutant et greenhouse gas to understand the data and the factors influencing the trends observed, inclunding regulatory framework (read the SECTEN report online via your login and password).

The pollutants and greenhouse gases inventories made by CITEPA are produced in an objective and impartial manner.

All the methods used to produce those pollutants and greenhouse gases inventories are explained and detailed in the OMINEA report, made by CITEPA. A database including the activity data and the emission factors applied is also available on this website.

These methods, used for the estimation of both pollutants and greenhouse gases, are internationally accepted methods. Concerning the pollutants, the methods applied are consistent with the EMEP methodology, and concerning the greenhouse gases, with the GIEC methodology.

CITEPA is annually audited by international experts (UNFCCC and UNECE) in order to control these methods are properly applied.
