Table explanation


This table contains figures on the emissions in the Netherlands by mobile sources. These are actual emissions in or above the Netherlands and on the continental shelf (see paragraph 2). It also contains the emission factors derived from these emissions (in grams of emission per kilogram of consumed fuel).
Mobile source emissions are caused by the combustion of motor fuels, the evaporation of fuel and load residues (VOC), wear of tyres, brake linings and road surfaces (PM10), and the wear of railway overhead contact lines, including emissions caused by friction and spark erosion of the current collectors.
The emissions are calculated by multiplying data on activities, for instance vehicle kilometres and fuel consumption, by emission factors.

Data available from 1990 to 2018.

Status of the figures:
The 2018 data is provisional; all other data are final. The status of the figures will not be changed, because this table has been discontinued.

Changes as of 18 March 2020:
None, this table has been discontinued.

Changes as of 11 September 2019:
Adding provisional figures of 2018.

Changes as of 26 February 2019:
- Replacement of 2017 provisional figures by definitive figures.
- Based on TNO data the NOx emission factor for diesel trains has been raised for the entire time series.
- As a result of recent measurements by TNO adjustments have been made to the set of emission factors for road traffic
- There have been minor corrections of the road vehicle mileages of recent years. Obviously this has consequences for the emissions of the years concerned.

When will new figures be published?
Not applicable anymore.
This table is succeeded by Emissions to air on Dutch territory; mobile sources. See paragraph 3.

Description topics

Emission factors
Average emission in grams per kg fuel consumed.
CO
Carbon monoxide.

CO is caused by incomplete combustion of fuels. It is a toxic gas (detrimental to health).
VOC by combustion
Volatile organic compounds, combustion emission.

Caused by incomplete combustion of fuels. Smog generating and sometimes carcinogenic.
NOx
Nitrogen oxides (NOx = NO and NO2, calculated as NO2).

Nitrogen oxides are formed in the engine by the combustion of nitrogen from ambient air. Nitrogen oxides cause acidification and play a role in smog generation. Nitrogen dioxide (NO2) is detrimental to health.
PM10
Particulate matter (PM10 = particulates with diameter smaller than 10 micrometres).

Almost 80 percent of the PM10 emission by mobile sources is caused by diesel fuel combustion. About 15 percent originates from various wear processes like the wear of tyres, brake linings and road surface. Detrimental to health, penetrates deeply into the lungs.
SO2
Sulphur dioxide (SO2 and SO3, calculated as SO2).

SO2 is formed by the combustion of Sulphur in fuels. Causes acidification.
CO2
Carbon dioxide (CO2).

CO2 is formed by the combustion of Carbon in fuels. Greenhouse gas (causes the temperature of the earth's atmosphere to rise gradually).
CH4
Methane (= natural gas).

Methane is one of the components of VOC. In the case of mobile sources it is only a minor part of the total VOC emission. Methane is a greenhouse gas (causes the temperature of the earth's atmosphere to rise gradually).
N2O
Laughing gas/dinitrogen oxide.

Dinitrogen oxide from mobile sources is mainly formed during the warming up phase of catalytic converters, as a result of incomplete conversion of nitrogen oxides (NOx) into nitrogen (N2). N2O is a greenhouse gas (causes the temperature of the earth's atmosphere to rise gradually).
NMVOC
Non-methane volatile organic compounds (combustion+evaporation).

Caused by combustion of fuels, evaporation of petrol from the vehicle fuel system, of cooling agents from air conditioners, and from car products like screen washer liquid. Furthermore VOC emissions are caused by the evaporation of inland vessel load residues. Smog generating and sometimes carcinogenic.
