Before the full implementation of CO2 capture and storage, a demonstration of its safety is needed through the implementation of reliable risk management methods. One important aspect of risk management is the development of mitigation measures that prevent any risk to the environment or human health. This paper presents a database that includes a set of risk mitigation measures, their description and main properties, and references. They are organised in connection with a detailed approach of risk events developed into bow-tie diagrams by BRGM. The goal of the database is to help the setting up of corrective measure plans that will be mandatory for all projects under the European directive on CO2 storage.
