About the Industrial Safety site

The Industrial Safety site is dedicated to sharing information and data related to the EU Seveso Directive. This covers two key pieces of information:

• data on the establishments covered by the Directive
• information on major accidents and near misses that involve hazardous substances covered by the Directive

Resources for Seveso Competent Authorities

Reporting data on major accidents and near misses

According to the provisions set out in Commission Implementing Decision (CID) 2022/1979, from January 2026 the European Environment Agency takes over the responsibility for the database referred to in Article 21(4) of the Seveso III Directive 2012/18/EU regarding details of the major accidents which have occured within the territory of Member States. Prior to these provisions, the responsibility for collecting data on major accidents and maintain such a database was held by the JRC Major Accident Hazard Bureau (MAHB). Therefore, the setup of the database at the EEA requires the transfer of the information on major accidents collected over the years at JRC to the EEA. Since 2023 the EEA, in collaboration with the MAHB, has been developing and testing a set of procedures to securely transfer the content of the Major Accident Reporting System (eMARS) hosted at the JRC to the EEA systems. The actual transfer of the data took place after the data reporting to the MAHB system was disabled during the last quarter of 2025.
The requirements for the data content for accident reports has not changed and are guided by the Commission Decision 2009/10/EC. As such, the EEA did not change the content of the reports but adapted it for the EEA systems. To confirm the data transfer, the EEA has set up a confirmation procedure with the objective of ensuring that the data transferred to the EEA system is consistent with the deliveries made by countries.

Reporting data on the establishments covered by the Directive

According to the provisions set out in Commission Implementing Decision (CID) 2022/1979, the European Environment Agency takes over the responsibility for the database referred to in Article 21(3) of the Seveso III Directive 2012/18/EU regarding the Seveso Establishments from January 2026. Prior to these provisions, the responsibility for collecting data on Seveso Establishments and maintain such a database was held by the JRC Major Accident Hazard Bureau (MAHB). Therefore, the setup of the database at the EEA requires the transfer of the information on Establishments collected over the years at JRC to the EEA. Since 2023 the EEA, in collaboration with the MAHB, has been developing and testing a set of procedures to securely transfer the content of the Seveso Plant Information Retrieval System (eSPIRS) hosted at the JRC to the EEA systems. The actual transfer of the data took place after the data reporting to the MAHB system was disabled during the last quarter of 2025.

The data transfer procedure consists of two steps:
1. the entire eSPIRS database is transferred to the EEA,
2. the content of the eSPIRS database is converted to the format relevant for the new CID and is used to populate the new EEA reporting system

Since the operations in step 2 require some level of manipulation of the original data in order to align with the new data format, the EEA has set up a data verification procedure with the objective of ensuring that the data transferred to the EEA system is consistent with the deliveries made by countries.
