Emission relocation tool
Key features of this online web tool:
- Easily download high-resolution emission data for the entire Europe.
- Select specific areas of interest and download high-resolution emission data for those areas.
- Upload your emission data and combine it with high-resolution emission data in your chosen areas.
Data description available in our tool:

- 2019 – Datasource: EMEP/CEIP 2021, Spatially distributed emission data as used in EMEP models
- relocated data available at three resolutions: 0.025, 0.01, 0.005
- available pollutants: BaP, PM10, PM2.5, NOx, NMVOC, SOx, NH3
- coordinate system of data: WGS84
- data for 2017 and 2019
- whole Europe available for download in two formats: tiff and Cloud Optimized GeoTIFF
Methodology of emission relocation process:
The objective of the methodology was to establish a reliable framework for relocating emission data from low-resolution to high-resolution data. The relocation process has been specifically developed and tested on EMEP data (available at https://www.ceip.at/the-emep-grid/gridded-emissions) with an initial resolution of 0.1°x0.1°. The methodology successfully relocates this data to three alternative resolutions: 0.025°x0.025°, 0.01°x0.01°, and 0.005°x0.005°. Furthermore, the methodology can potentially be applied to other datasets with varying resolutions, thereby allowing for scalability and broader applicability. The main assumptions of methodology are:
- Relocation process is based on proxy data
- Total emission load per original low-resolution grid is preserved
- Output categories follow GNFR sectors
To improve the spatial distribution of emission sources, we use additional data, i.e. proxy (complementary) data, using sources such as Corine Land Cover or Open Street Map, which allow precise relocation of emissions.
For example, the road network from Open Street Map allows us to detail (improve) the spatial distribution of traffic emission sources.
The relocation process relies on proxy data, which covers all of Europe consistently. Proxy data specific to each GNFR sector is required to ensure accurate relocation based on sector activities. Land use data plays a crucial role in determining emissions indirectly, and we opted to utilize Corine Land Cover and Open Street Map (OSM) due to their consistent and well-maintained coverage across Europe. In certain sectors, more detailed proxy data was incorporated from different sources to enhance accuracy. These include:
Airport Operations Database (https://ourairports.com/continents/EU/) for GNFR H
Ship density (https://www.emodnet-humanactivities.eu/) for GNFR G
Large combustion plants (https://www.eea.europa.eu/data-and-maps/data/industrial-reporting-under-the-industrial-6) for GNFR A and B.
