One study which compared the cost of adaptation with the cost of inaction at the European Union level finds that by 2020, the net benefit of adaption will range between €3.8 billion (low sealevel-rise scenario) and €4.2 billion (high sea-level-rise scenario). These benefits are expected to increase further by 2080
