In the concluding chapter, we take stock of the legal developments that are likely to shape the implementation and further development of liability rules and process in areas beyond national jurisdiction. We argue that the developments in relation to state obligations of due diligence, the widening scope of compensable damages and the potential for more inclusive rights of standing, as well as rights for states to take response measures in areas beyond national jurisdiction, provides a strengthened foundation for a more robust system of state responsibility for environmental harm in areas beyond national jurisdiction. In recognizing that the approaches to civil liability in areas beyond national jurisdiction remain underdeveloped, we examine the central challenges that remain, as well as some modest pathways towards stronger legal accountability for environmental harm in the global commons.
