2. Emission inventory for EMEP in Belarus
3. Regional inventory: experts estimates
4. Connections between inventories: national and RAINS
5. Sources of uncertainty and prioritizing
Institutional arrangements of state emission inventory in Belarus
Emission inventory system in Belarus is based on annual
statistical reporting of enterprises. Primary reporting forms are
summarized by regional offices of the Ministry on Statistics
and Analysis.
Main office of the Ministry on Statistics and Analysis
generalize reports of the regional offices and produce annual
report on air protection in the split of regions, branches of
economy, cities and ministries.
The data on emissions in annual reports includes data on
emission of main pollutants (SO2, CO, NOx, hydrocarbons and
VOC) and specific pollutants (more than 70).
Data on emission of the main pollutants is given divided into
emission from fuel combustion and emission from
technological and other processes.
Additional information in the annual report: number of reported
enterprises, number of sources of emission, level of
abatement etc.
Annual emission reporting system summarizes data from
more than 2000 enterprises; it is assumed that they represent
about 95% of total emission.
Specific features of state emission inventory system in Belarus
- Emissions in national statistics are summarized according to
branches classification scheme (so-called OKONH) which did
not coincide with SNAP and NFR classification schemes.
Additional information is necessary for distribution of emission.
- Mobile sources emission are not reported. They are estimated
by the consumption of fuel on the national and region levels.
- Domestic sources (for instance, heating) are not taken into
account.
- Agriculture sources (collective farms, agricultural activities on the whole) are not taken into account in a regular way.
- Waste management and disposal are not accounted
regularly (except CH4 in GHG inventory and waste
incineration).
- Solvents and paints application generally are not considered
except industrial activities.
- There are no information on emission of some pollutants (all
POPs, HM – mercury, Zn, Se, PM10 and PM2.5)
EMEP emission inventory
EMEP inventory report is prepared using the following
methodology:
1. Emission data on pollutants which sources are rather
completely covered by statistics
This data was distributed by SNAP and NFR classification
schemes and reported as-is (main pollutants – SOx, NOx,
CO). VOC emission data was also prepared by this approach.
2. Emission data on pollutants some sources of which are not
covered by national statistics (NH3, TSP, heavy metals)
For these sources emissions were calculated by the simplest
approach (using emission factors) and these values were
incorporated in common reporting table together with statistical
information.
3. Emission data for pollutants for which there are no any
information in statistics (all POPs)
For these pollutants emissions were calculated by simplest
approach using emission factors and included into the report.
Initial statistical data for emission calculation
Data of the Ministry on Statistics and Analysis, data of the
Ministry on Natural Resources and Environmental Protection,
Ministry on Emergency and some others are used for
emission assessment.
Emission factors are taken from the Atmospheric Emission
Inventory Guidebook (2002) and by results of own emission
sources testing as a contribution to EMEP (Belarusian
contribution to EMEP 1996-2004) – for heavy metals and POPs.
Parallels between national and SNAP (NFR) sources classifications Emission report on the Ministry on Statistics and Analysis gives main pollutants distributed by fuel combustion emission and technological process emissions. This makes possible to reclassify emissions into SNAP and NFR formats using the following aggregation;- category “combustion in energy production and transformation” was considered as equivalent of the SNAP sector 1;- category “sold to population” – as category SNAP 0202;- category “combustion in residential and communal sector” – as category SNAP 0201;- category “used for transport” – as analogous of the sector 07+08;- difference between “used directly as fuel” and sum of “combustion in residential-communal sector” and “used for transport” – as SNAP 0301.

Greatest missing sources in emission inventory are in sectors
1A4b (Residential – some subsectors), 3A (Paint application),
3B (Degreasing and dry cleaning), 4D (Agricultural soils).
Main contribution of missed emission sources for main
pollutants are expected into NMVOC. Some missing are also
into PM, SO2, NOx and CO.
Expert emission estimates: regional emission inventory
Here is an example of expert estimates of emission of certain pollutants for improvement of data completeness (INTAS project ).
Pollutants: key heavy metals (mercury, lead, cadmium).
Base years: 1990, 1995, 1997.
Region: 12 Former Soviet Union countries
Emission estimation domain
Methodology and procedure
Methodology of emission estimation was based on emission factors and production statistics application.
Heavy metals emission statistics for NIS especially for Central Asia is very scarce. Only lead data can be found. Emission from vehicles and sometimes from non-ferrous industry are estimated. Obtaining of full information on production and usage statistics is troubled by statistics imperfection in the NIS countries. For instance, there is a scarce information on leaded gasoline usage.
Spatial types of emitters
Area sources
Stationary fuel combustion, mobile sources, some ferrous industry processes (gray iron foundries, electric steel plants), mineral products industry, most of chemical products industries, some others have been considered as area sources.
Administrative regions (provinces or the whole small countries, capitals and some large cities were considered as elemental units of area sources. Area sources emissions were distributed according to density of population (rural and urban).
Large point sources
Ferrous and non-ferrous works, and some others (SNAP 010406, 030203, 030301, 030304, 030305, 030306, 030307, 030308, 040205, 040206, 040301, 040413) are considered as point sources of HM emission.
Additional information for this category was gathered in order to obtain more precise estimates of emissions and their spatial distribution
Some resultsLead emission
Annual anthropogenic lead emissions were decreased in the
countries of the FSU from 24903.0 tonnes in 1990 up to 9652.5
tonnes in 1997).
Share of European NIS in total lead emission of the NIS
decreased from 19% in 1990 to 12% in 1997. Share of Russia
was rather stable within 53-55%, share of Central Asia NIS
increased from 24% to 32%.
Greater contributions among the source categories were fulfilled
by road traffic due to use of leaded gasoline (48% in 1990 and
26% in 1997) and production of non-ferrous metals (30% in 1990
and 50% in 1997).

Trends in spatial structure of lead emission in European NIS
Differences between current and previous estimates of
anthropogenic lead emissions are mainly within 30-70% for
European NIS although presented data for the Ukraine are 2.6
times lower for 1995 and 1997 than ones mined from other
sources. The results of presented estimates for Central Asia NIS
(Kazakhstan and Uzbekistan) are significantly higher than data
prepared by national experts (World Bank, 1998). This differences
are appeared due to the fact, that non-ferrous metal industry
rather developed in these countries was not almost taken into
consideration in that document because road transport was
ultimately considered as the most important lead emission source
with correspondent inputs of 62-72% in Kazakhstan and 86-95%
in Uzbekistan.

RAINS analysis and application
RAINS analysis was performed to test its applicability for PM emission inventory for Belarus.
Were checked:
- fuel totals and distribution of fuels by sectors;
- distribution of fuels by type of installations;
- activity projection;
- control options and types of abatement used;
- PM emission factors.
1. Fuel balanceShare of solid and liquid fuels seems overestimated
2. Shares of fuels consumption by sectors
Generally share of small combustion is underestimated and
share of power generation is overestimated.
3. Shares of fuel consumption by type of installation.
Some approaches and routines were elaborated for estimation
of the share of stoves, fireplaces, small and medium boilers etc.
in residential sector. Generally share of grate firing and stoves
is underestimated.
3.Level and types of abatement installation used for fuel
combustion
Generally RAINS is based on analysis of West Europe situation
with abatement and control options and levels of abatements
used for Belarus are too high.
4. Emission factors
The analysis of emission factors is in progress because no PM
speciated emission factors available for Belarus.

For future discussion:Sources of uncertainty in international emission
inventoriesInternational inventories generally contains not emissions but
statistical data (projections) and EF (technologies parametrization).
So uncertainties result from quality of last datasets.
Statistical datasets
- quality of international statistics is unequal for different years;
- generally out of date in comparison with national.
Emission factors and their parametrization
- type of abatement and its efficiency,
- distribution of installations by type etc.
Prioritizing in emission inventories
- high accuracy of estimates (to estimate only reliable sources with
good emission ) or completeness (to estimate all sources)?
- good national totals (main attention to priority sectors) or good
sector estimates?
- accurate estimates for certain years or reliable estimates (same
quality) for a raw of years (to detect trends)?
- hard common format or listing of distinct sources?
- common format for all pollutants or distinct source;
- requirements to spatial distribution?
In general how to measure quality of inventories (intercomparison?)
