BACKGROUND



The decision trees in the IPCC good practice
guidance are used to choose a good practice
method that suits national circumstances.
The UNFCCC-NAI Software contains, basically, the
methods of lesser complexity that countries can
use to prepare their inventories.
However, in principle, the software can be used to
report the estimated emissions independently of
the complexity of method used (Tier 2, 3, etc).

- In the current software the CO2 emissions from cement

2-1s1A for emissions from cement production proper, and
Table 2-1s1B for emissions from clinker production, which
take into account the CKD factor (Tier 2). Please only fill
EITHER sheet 2-1s1A OR Sheet 2-1s1B.
- The emissions of SO2 are calculated from cement
production (Tier 1 only).
- The default emission factors in the IPCC Guidelines
correspond to 100% of CaO (or CaO.MgO) in lime and can
lead to an overestimation of emissions because the CaO and
MgO content may be less than 100%.
Suggestion:
Calculate EF outside the software using stoichiometric
ratios and CaO (CaO.MgO) content by lime type (or use
default values for calculating EF). After having obtained
the EF, emissions can be calculated directly in the
software.

Remarks
CO2
- If activity data are available then there are few difficulties encountered
in using the software to obtain CO2 emissions (both using Tier 1 and
Tier 2 method).
Suggestions:
- To estimate the emissions from iron and steel separately and
obtain the total of emissions; do the calculations outside the
software and incorporate the results manually into the Sectoral and
Summary Tables. For steel produced in electric arc furnaces also
add the carbon released from consumed electrodes.
- Lime added to electric arc furnaces and its CO2 emissions should
be accounted for in the lime use section.
- When biomass carbon is used the emissions should be reported in
the land-use change and forestry sector.
Alert: The estimation of CO2 emissions based on production data
and production base EF (Worksheet 2-11s2) is not considered to be
good practice.
