Netherlands Pollutant Release and Transfer Register (Emissieregistratie)

The official figures on what the Netherlands emits: greenhouse gases, nitrogen, particulate matter and hundreds of other substances, to air, water and soil. Per sector, per source, per municipality or province, and separately for large companies. From 1990. The Netherlands uses the same figures for its international reporting. The national totals are also available as a CBS table, with an open API.

CO₂ emissions by source: energy sector is the largest part, 30% in 2025

Breakdown in 2025: energy sector 30%, transport and mobile machinery 26%, industry and construction 20%, agriculture, services and waste 14%, households 9.6%. Total: 142.2 megatonnes.

What can you do with it?4 ideas

Getting started

CO₂ since 1990

Plot total CO₂ emissions on Dutch territory as a line. According to CBS table 85668NED they were 170.9 billion kilos in 1990 and 142.2 billion kilos in 2025 (provisional).

Getting started

The biggest emitters in your province

Companies covered by the European PRTR rules report their emissions per substance. The company reporting tool shows per company what went into the air or water.

Advanced

Nitrogen per municipality

Export ammonia and nitrogen oxides per municipality and per sector. Where does most come from agriculture, and where from traffic or industry?

Advanced

The quarter after the year

CBS calculates provisional quarterly figures for greenhouse gases (table 84979NED). That lets you see within the current year whether emissions are rising or falling.

How to process it4 steps

National totals via the CBS API
Table 85668NED has ten substances and 50 emission sources. This fetches total CO₂ emissions per year, in million kilos. The source key is padded with spaces: 'T001176 '.

```
Regional figures via the export module
For municipalities, provinces, sectors and more than 375 substances, use the export module on the site. You choose years, substances and areas and download the result. There is no documented API behind it.
```
https://www.emissieregistratie.nl/data/data-export
```
Map layers via WMS
The data portal's maps run on a GeoServer with ten layers, such as companies, municipalities and river basins. WFS is disabled, so only images, no data.
```
https://data.emissieregistratie.nl/geoserver/wms?service=WMS&request=GetCapabilities
```
Know which year is final
Every September, provisional figures for the previous year are published. The final figures for 2025 appear in early 2027. The whole series is then recalculated: always fetch everything again.

Interesting combinations

gemeente

Which municipality emits the most per inhabitant?

Divide emissions per municipality by the number of inhabitants from the key figures. Watch out for large point sources (a power plant, a factory) that push one municipality up sharply.

Combine with Key figures for districts and neighbourhoods

locatie en jaar

Does concentration fall along with emissions?

Compare the trend in nitrogen oxide emissions in a region with the annual mean NO₂ at the stations there.

Combine with Luchtmeetnet air quality network

IE
Industrial Emissions Portal (EEA) not in the index yet

What to watch out for

Regional figures sit behind a web form
The export module is a web application without a documented API. Addresses such as data.emissieregistratie.nl/export even return HTTP 404, although the browser shows the app normally. Scripts can only fetch the national totals (via CBS) and the WMS images.
Figures change afterwards
With every new round the whole series from 1990 is recalculated with the latest method. Never compare an old figure with a new figure from a later publication.
Regional figures are partly estimated
Part of the emissions is distributed across the country, for example by number of jobs. That sometimes gave high emissions at a head office location; the method was adjusted with the 1990-2024 series (September 2026).
Territory or economy
Table 85668NED counts emissions on Dutch territory. CBS also has a table on emissions by the Dutch economy (83300NED, national accounts), with a different scope. Always state which one you use.

Limits and pitfalls

At most 10,000 rows per request; page with $skip. experience
This is the CBS table with the national totals from the Emissieregistratie. Regional figures and companies are only in the export module on emissieregistratie.nl. experience
Emissiebronnen keys are padded with spaces ('T001176 ' is the total). Substance codes are not: 'A044109' is CO₂. tested
The years 1991 to 1994 and 1996 to 1999 are missing; the series jumps from 1990 to 1995 to 2000. from the description
The unit is million kilos (mln kg). 142,200 therefore means 142.2 billion kilos, or 142.2 megatonnes. from the description
