Pollutants and greenhouse gas concerned

The pollutants and greenhouse gases covered by CITEPA's inventories for the sector of energy production, transformation and distribution are presented in the table below:

Pollutants concerned Environnemental Effet/Impact
SO2, NOx, NMVOCs, CO, NH3 (small amount) Acidification, eutrophication, photochemical pollution
CO2, CH4 (small amount), N2O (small amount), HFCs (small amount), SF6 Enhanced of the greenhouse effect
As, Cd, Cr, Cu (small amount), Hg, Ni, Pb (small amount), Se (small amount), Zn (small amount) Heavy metals contamination
Dioxins/furans (PCDD-F), PAHs*, PCB, HCB Persistant organic pollutants contamination
Total suspended particules (TSP) (small amount), PM10 (small amount), PM2,5 (small amount), PM1,0 (small amount), 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 sector of energy production, transformation and distribution, usually called energy industry, includes several activities, such as combustion sources (boilers, turbines, engines), as well as, decarbonising sources (due to carbonates used for the desulfurisation) and fugitive emissions.

This sector is divided into several sub-sectors:

  • centralised electricity production,petroleum refining,
  • district heating,
  • extraction and distribution of liquid and gaseous fuels.

The full list of sources considered for the sector of energy production, transformation and distribution 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 sector of energy production, transformation and distribution 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).

Example: La baisse des émissions de la production d’électricité s’explique essentiellement par la variation du mix énergétique avec le développement marqué des centrales thermiques au gaz naturel ces dernières années.
La nette diminution des émissions en 2014 est liée, ... (to read more, consult the SECTEN report online via your login and password).

 

Method

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.
