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 up to and including reporting year 2019 are final. The figures for 2020 are provisional. In order to obtain a coherent and consistent time series, the complete time series is (re)calculated every year, so that the latest insights, especially with regard to the emission factors, can be included in the calculations.

Changes as of 5 October 2021:
- Addition of provisional figures for 2020.
- The NOx and NMVOC emissions from manure management and agricultural soils no longer count according to the current implementation of the NEC guideline and will be omitted from now on for all years.

Changes as of February 16, 2021:
- Replacing provisional figures 2019 by final figures.
- Some of the emissions are recalculated on the basis of new data from the energy balance (updated by Statistics Netherlands). The figures for 2018 and 2019 have been adjusted and the figures for 2015 up to and including 2017 have been revised. As a result, the emissions have changed for those years.
- The emissions of methane and particulate matter in households, as a result of space heating using natural gas, have changed for all years due to the application of new emission factors.
- The emissions of N2O, NH3 and NMVOC from agriculture have changed because calculations have been made with a new data model, in which the allocation to manure over grassland and arable land has changed. The emission factors for ammonia from low-emission animal houses have also been adjusted. The emissions of the entire 1990-2019 time series have been adjusted.

When will new numbers be released?
Final figures for 2020 will be published in March 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.
