This final report summarizes the work results of the activities undertaken to support the ⁠UN⁠/⁠OECD⁠ Natech (Natural Hazard Triggered Technical Accidents) II project. The report is based on the report submitted to the Organisation for Economic Co-operation and Development (OECD) Working Group on Chemical Accidents (WGCA) before its 28th meeting and the comments received. The contents can be divided into four sub-categories:

1. The final evaluation of the results of the survey by the steering group;
2. A description of the sessions and the presentations made at the UN/OECD Natech-II-Workshop;
3. A description of the record of good practice examples in Natech risk management;
4. The recommendations generated at the workshop.

The OECD intends to publish its own report on Natech Risk Management on the basis of this one.
