The OMINEA report is the reference document for a) the description of the national system of greenhouse gas and air emissions inventories and b) the methodologies used to compile the different inventories (UNECE/NEC, UNFCCC, LCP, SECTEN, etc.).
Framework
Estimating the quantities of pollutants released into the atmosphere from human and natural sources requires a great deal of data and fairly specific methods to produce what are conventionally known as "emissions inventories" or "registers", depending on the survey characteristics in terms of spatial resolution and emission sources.
Description of the national system of emissions inventories
The OMINEA report describes the national system of greenhouse gas and air emissions inventories in terms of organisation, allocation of responsibilities and scope. Operational technical procedures are described as well as information on reference nomenclature and codes, procedures for verification, quality assurance and estimating uncertainties, etc.
Methodologies used to compile national emissions inventories
The methods used for each category of emission sources are given for several dozen substances classified under "greenhouse gases", "acidification and photochemical pollution", "eutrophication", "heavy metals", "persistent organic pollutants", "particulate matter" and "others". The sectors are indexed in accordance with the international format defined by the United Nations Conventions on Climate Change and Long-range Transboundary Air Pollution.
Some information on the 10th edition of OMINEA:
- 18% new sections (+3.2%),
- 29% of the sections are unchanged,
- 19% of the sections deal with editorial changes only (better syntax, mistakes corrected, improved layout, etc.),
- 15% are simply updated (data added relative to last year only),
- 16% have retrospective modifications (excluding methodology modifications),
- 12% of sections' modifications concern methodology items (ranging from limited changes to complete revision),
- 6% of sections are concerned by other changes (example: inventory system description, global explanation, etc.).
The latest edition of the OMINEA report provides more detailed information on the section status. A new classification of flags has been developed. The following table presents the distribution of sections and flags as occurring in the 10th edition of the report.
| Section/flag | ° | M | V | A | D | F | X | Total |
| COM |
2 |
22 | 19 | 18 | 29 | 56 | 12 | 158 |
| GES | 3 | 24 | 24 | 9 | 0 | 14 | 30 | 104 |
| AP | 3 | 3 | 27 | 20 | 2 | 7 | 24 | 86 |
| E | 2 | 0 | 5 | 8 | 0 | 1 | 38 | 54 |
| ML | 3 | 3 | 6 | 9 | 1 | 7 | 24 | 53 |
| POP | 2 | 7 | 3 | 7 | 1 | 9 | 20 | 49 |
| PM | 3 | 11 | 6 | 16 | 2 | 13 | 20 | 71 |
| AUT | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 1 |
| Total | 18 | 70 | 90 | 87 | 35 | 107 | 169 | 576 |
Horizontal Key:
° = new section ;
M = methodology modified ;
V = retrospective change of data ;
A = data updated for the last year only ;
F = editorial change ;
D = other ;
x = no change
Vertical Key:
COM = generic section ;
GES = section on greenhouse gas ;
AP = section on acidification and photochemical pollution ;
E = section on eutrophication ;
ML = section on heavy metals ;
POP = section on persistent organic pollutants ;
PM = section on particulate matter ;
AUT = section on other items
