Table description


This table contains figures on the emissions in the Netherlands by stationary and mobile sources, calculated according to the NEC-directive (NEC = national emission ceilings). This directive has been drawn up in 2001 by the European Parliament and the Council of the European Union to set upper limits for the total emissions of SO2, NOx, NH3 and non-methane VOCs by each member state.
The calculation of emissions by stationary sources is, among other data sources, based on specifications in the annual emission reports of separate enterprises and additional estimates based on production and energy data provided by Statistics Netherlands.
According to the activity classification (SIC 2008) the coke factory of Tata Steel belongs to the energy sector. In this table it’s emissions are assigned to the category manufacture of iron and steel.
The emissions by road traffic and fisheries in this table are based on the amount of motor fuels sold. The NEC emission ceilings of 2010 were at the time determined on the basis of fuel-used. The emissions calculated by this method can be found in the tables concerning emissions to air on Dutch territory.

Data available from: 1990

Status of the figures:
The 2019 figures are provisional, all other figures are definitive. 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 1 September 2020:
Provisional figures of 2019 has been added.

When will new figures be published?
Defintive figures of 2019 will be published in March 2021.

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.
