Introduction

The 6th IEAGHG Risk Assessment Network Workshop was held from the 21^st to the 23^rd of June in Pau, France hosted by BRGM; sponsored by BRGM and International Performance Assessment Centre for the Geological Storage of Carbon Dioxide (IPAC-CO₂).  54 participants attended the workshop from 15 different countries. 

The three day workshop highlighted the latest international CO₂ storage risk assessment developments, discussing communication and regulatory developments, risk and incident management, potential induced seismicity, monitoring performance, understanding potential groundwater impacts, risk assessment methodologies, key outcomes and identified knowledge gaps which need to be addressed in future research.  Participants were fortunate to visit the TOTAL Lacq-Rousse project on the 3^rd day of the workshop, including the oxy-combustion capture site and the storage site in the afternoon, with a TOTAL sponsored lunch. 

The agenda and presentations from the meeting are available in the network members’ area of the IEAGHG website (www.ieaghg.org). The previous workshop agenda, presentations and report are also detailed on this website.

Conclusions 

The recurring lessons were identified as:

• A participatory process in pivotal in Risk Assessment, particularly for community assets, and benefits and impacts should be discussed not just numbers.

• The objective of the Risk Assessment method is more important than the method itself, though it is important to note the process use for traceability.

• Monitoring should be risk-based.

• Baseline data is crucial.

• Risk Assessment should be systematic and evidence based using collective judgement.
