MalteG Dear EAA Team

I am working on a research project on the environmental impact of mining in Europe. I therefore used the PRTR register to find the pollutant emissions from the NACE section B (Mining and Quarrying).

Now I notice a relatively strong discrepancy between the PRTR data and the data provided by eurostat (
https://ec.europa.eu/eurostat/de/data/database). Using the example of NOX emissions in 2015, according to PRTR (ReportingYear 2015; Excluding Norway, Switzerland, Serbia and Iceland, NACE activities 05.10 - 09.90), there has been an output of 53,544 tons of NOX. According to the eurostat database (same countries, NACE section "Mining and quarrying") the output was 122,821 tons of NOX.
These deviations seem to occur for other pollutant parameters as well.

Now the question to the experts: Why do the data deviate by the relatively large factor of more than 2? Is this discrepancy known? And finally, which datasource is more reliable in terms of the possibility to relate pollutant outputs to certain industrial sectors and shall be used by scientists/decision makers etc.?

Looking forward to your reply. Please let me know if you have any questions.

Best regards
Malte
