|
|
|
54
|
***Methodology and Data Updates from Previous Release
|
|
55
|
|
|
56
|
Update default emissions data to EDGAR v6 (air pollutants to 2018), EDGAR v8 (CH4, N2O to 2022), latest FAO (agriculture CH4 and N2O to 2020), Andrew (CO2 cement to 2022)
|
|
57
|
|
|
58
|
Updated inventory scaling for Argentina, Australia, Canada, EMEP, Korea, Taiwan, UNFCCC (Annex I GHGs), and United States.
|
|
59
|
|
|
60
|
Update to latest OMI/TropOMI composite SO2 point source catalog (through 2022)
|
|
61
|
|
|
62
|
Improved flaring emissions extension over recent years using flaring volumes and additional data flaring emissions time series
|
|
63
|
|
|
64
|
Improved recent year extension of liquid fuel consumption
|
|
65
|
|
|
66
|
Update shipping fuel sulfur and incorporate new international S content agreements (IMO), adjusted for non-compliance. Shipping activity data updated.
|
|
67
|
|
|
68
|
Sectoral detail added for metal processing sectors (3 new sectors)
|
|
69
|
|
|
70
|
Additional detail in emissions, now released by fuel, country, and sector.
|
|
71
|
|
|
72
|
Numerous country and sector-specific updates.
|
|
73
|
|
|
74
|
***Major Emission Changes from Previous Release
|
|
75
|
|
|
76
|
Global emissions continue to decrease over recent years for SO2, OC, BC, CO, NOx, with the largest decrease in SO2. Only modest changes in global NMVOC.
|
|
77
|
|
|
78
|
NH3, CH4, N2O, and CO2 emissions are increasing, although CO2 emissions in 2022 were nearly the same as in 2021.
|
|
79
|
|
|
80
|
Overall lower road transportation emissions for many species in regions without country-level inventories, largely due to lower incomplete combustion emissions, particularly CO and NMVOC, in non-OECD regions in EDGAR v6.
|
|
81
|
|
|
82
|
Revisions in historical EDGAR estimates result in fairly monotonic increase in CH4 emissions over time
|
|
83
|
|
|
84
|
***Known Issues
|
|
85
|
|
|
86
|
Nigeria and Ethiopia residential biomass emissions, other than BC OC, are likely overestimated in this release .
|
|
87
|
|
|
88
|
Some SO2 emissions detected by OMI/TropOMI may not be included yet, although these are small overall
|
|
89
|
|
|
90
|
CO2 process emissions from primary and secondary metal production is currently allocated entirely to the 2C1_Iron-steel-alloy-prod sector. Some of these emissions are from the production of other metals.
