Table description


This table contains figures on the emissions of air pollutants, calculated according to the European NEC guideline (NEC= National Emission Ceilings). This concerns the emissions to air from stationary and mobile sources in the Netherlands of ammonia (NH3), nitrogen oxides (NOx), sulfur dioxide (SO2), particulate matter (PM10; particles with a diameter smaller than 10 micrometers), carbon monoxide (CO) and volatile organic compounds, excluding methane (NMVOC). In this table the emissions from the coking plant of Tata Steel (Hoogovens) are included in the base metal industry (and therefore not in the energy sector) and the emissions from road traffic and fishing are based on the sales of motor fuels.

Data available from: 1990.

Status of the figures:
All figures are final. In order to obtain a consistent time series the complete data set is (re)calculated when necessary, so as to be able to include the latest insights in the survey, especially in the case of emission factors.

Changes as of 9 March 2022:
Addition of final figures for 2020.

When will new figures be published?
Provisional figures for 2021 will be published in October 2022.

Description topics

NMVOC
Non-methane volatile organic compounds.

Among others caused by incomplete combustion of fuels and evaporation of fuels, cooling agents, inland vessel load residues, and other chemical substances. VOC emissions are also formed during various industrial processes. Smog generating and sometimes carcinogenic.
SO2
Sulphur dioxide (SO2 and SO3, calculated as SO2).

SO2 is formed by the combustion of sulphur in fuels. Causes acidification.
CO
Carbon monoxide.

CO is caused by incomplete combustion of fuels. Toxic gas (detrimental to health).
NOx
Nitrogen oxides (NOx = NO and NO2, calculated as NO2).

In particular nitrogen oxides are formed during combustion processes. With these atmospheric nitrogen (N2) is converted into NOx. Causes acidification and generates smog.
NH3
Ammonia.

NH3 is formed in particular during natural processes and also, to a lesser degree, during the combustion of fuels and during industrial processes. The most important source is manure. NH3 causes acidification.
PM10
Particulate matter (PM10 = particulates with diameter smaller than 10 micrometres).

Among other causes PM10 is formed during the combustion of diesel fuel, various industrial processes, and wear processes like the wear of tyres, brake linings, road surface, and railway overhead contact lines. Detrimental to health, penetrates deeply into the lungs.
