4.2.5 Recalculations
No source specific recalculations have been performed regarding emissions from production of
mineral products. However, a minor change has been introduced for lime, as the production of
hydrated lime has been included in the inventory. The trend and the size of the recalculation can
be found in Section 10.3.
4.2.6 Planned improvements
Regarding the production of cement a dialogue with the company will continue with the aim to
get more detailed information on production statistics (i.e. production of different types of clinker)
and corresponding emission factors.
Production statistics for glass and glass wool as well as information on consumption of raw materials
will be completed for 1990-1995.
The emission of CO 2 from products of expanded clay as well as CO 2 emissions from other processes
(e.g. flue gas cleaning, refineries, gas plants etc.) are not included at the moment, however,
these sources will be investigated and included.
4.3 Chemical industry (2B)
4.3.1 Source category description
The sub-sector Chemical industry (2B) cover the following processes:
• Production of nitric acid/fertiliser (SNAP 040402/040407)
• Production of catalysts/fertilisers (SNAP 040416/040407)
Production of nitric acid is identified as a key source.
The time-series for emission of CO 2 and N 2 O from Chemical industry (2B) are presented in Table 4.4.

1. Production of catalysts/fertilisers.
The emissions are extracted from the CRF tables and presented rounded.
The emission of N 2 O from the nitric acid production is the most considerable source of GHG from
the chemical industry. The trend for N 2 O from 1990 to 2003 shows a decrease from 3.36 to 2.89 kt,
i.e. -14%. However, the activity and the corresponding emission show considerable fluctuations in
the considered period.
From 1996 to 2003 the emission of CO 2 from the production of catalysts/fertilisers has increased
from 1.74 to 2.67 kt, i.e. 53% due to an increase in the activity.
