Table explanation


This table presents the air emission accounts, as a part of the annual environmental accounts compiled by Statistics Netherlands.
The air emission accounts describe the emissions of air pollutants and gases as a result of Dutch economic activities. This is including the emissions of residents abroad and excluding emissions of non-residents in the Netherlands. The emissions of the substances are allocated to the various economic activities. Emissions from natural sources are excluded as these emissions are not related to economic activities. In this table, the emission of pollutants and gases from stationary sources (such as power plants) as well as mobile sources (such as road transport) are allocated to the different industries or households. Included are CO (carbon monoxide); Total CO2 (carbon dioxide); CO2 (carbon dioxide) excluding emissions from biomass; CO2 (carbon dioxide) emissions from biomass; CH4 (methane);
N2O (nitrous oxide also known as laughing gas); NOx (nitrogen oxides (diversity)); SO2 (sulphur dioxide); NH3 (ammonia); PM10 (particulate matter with a diameter less than 10 micrometres); NMVOC (volatile organic compounds excluding methane (CH4)). The environmental accounts are compiled according to the concepts (such as the resident principle) and definitions of the national accounts, making it possible to quantify the environmental effects of the economic activities for the Netherlands in a consistent manner.

Data available from: 1990

Status of the figures:
Figures for the latest year are provisional. In order to obtain a consistent time series, the complete data set is (re)calculated every year.
The air emission accounts data are consistent in time and in compliance with the Dutch national accounts. The alignment between the environmental accounts and the national accounts however, takes place using a wide variety of sources. This means that, although every year the system required to perform the various calculations are similar and consistent, variation can occur due to changes in particular sources. As a result changes in emission factors from the emission inventory (pollutant release and transfer register, PRTR) and changing traffic and transport statistics affect the full time series of the air emission accounts. In order to obtain consistent time series, every year the entire time series are (re)calculated, enabling that latest insights in the data are captured.

Changes as of November 2025:
Data for 2024 have been added. Data for previous years are adjusted according to the revision policy (see: Status of the figures).

When will new figures be published?
New annual figures will be published in November.

Description topics

Greenhouse gases (climate change)
Greenhouse gases in the atmosphere retain part of the solar heat that reaches the earth. The increased concentration of greenhouse gases means more heat is retained and the temperature of the earth's surface rises.
This is called the 'enhanced greenhouse effect'. The most important greenhouse gases are carbon dioxide (CO2), methane (CH4), laughing gas (N2O), HFCs, PFCs and SF6.
CO2

Carbon dioxide.
Greenhouse gas (causes the temperature of the earth's atmosphere to rise gradually).
