3. Large point source Emissions in Europe 1990

3.1. Introduction

More data is generally needed for modelling and for compliance monitoring of large point sources in comparison to area sources. CORINAIR 90 provides the information on large point sources (LPS).

The emissions of these sources are especially interesting, firstly because they are responsible for poor local ambient air quality and, secondly because emissions from LPS contribute to long range transport of air pollutants.

3.2. Overview

For some pollutants large point sources (LPS) are responsible for a considerable share of the total European emissions (see table 9).

Table 9: Overview of European Emissions in CORINAIR 90

Pollutant	Emissions in ktonnes
	Area sources	%	LPS	%	Total
SO₂	9 034	32	18 839	68	27 874
CO₂	3 036 399	64	1 728 064	36	4 764 463
NO_x	13 130	73	4 792	27	17 923
N₂O	1 608	86	271	14	1 880
CO	64 493	93	5 219	7	69 712
NMVOC	21 120	97	650	3	21 770
CH₄	44 708	98	707	2	45 415
NH₃	5 649	99	52	1	5 701

Details on total emissions for all eight pollutants have already been published in the CORINAIR 90: Summary Report nr. 1 and nr. 2.

Figure 4 shows that SO₂, NO_x and CO₂ emissions of LPS are responsible for more than 20% of the European total. SO₂ is particularly interesting, where 68% of the total emission is caused by large point sources.

This chapter presents data on LPS for SO₂, NO_x, CO₂.

CORINAIR 90 distinguishes between a number of different air emission sources. Emissions from LPS are highly concentrated in a very few sources. This report therefore presents only LPS results for four source sectors. (see table 10).

Table 10: LPS emissions in Europe per source sector

Source sector	Emissions in ktonnes
	SO₂	%	CO₂	%	NO_X	%
Public Power Plants >300MW	13 691	74	1 160 276	67	3 316	69
Industrial Combustion Plants >300MW	1 781	9	178 877	10	430	9
Refineries	635	3	58 322	3	121	3
Inorganic Chemical Industries	201	1	9 726	1	136	3
Other	2 531	13	320 862	19	772	16
Total LPS emissions	18 839	100	1 728 063	100	4 775	100

The relative contribution of these four source sectors is given in figure 5, showing that Public Power Plants are by far the biggest source of LPS emissions.

From the vast amount of information on LPS made available in CORINAIR 90 the next chapter will present the ten largest LPS for SO₂, NO_x and CO₂ for the source sectors mentioned above.
