This contribution explores how climate-vulnerable states can effectively use the law to force action in order to address loss and damage from climate change, taking the Pacific Island state of Vanuatu as an example. Vanuatu made headlines when its Minister of Foreign Affairs, International Cooperation and External Trade, the Hon. Ralph Regenvanu, announced his government’s intention to explore legal action as a tool to address climate loss and damage suffered in Vanuatu. Our contribution places this announcement in the context of Vanuatu’s own experience with climate loss and damage, and the state’s ongoing efforts to secure compensation for loss and damage through the multilateral climate change regime. We then discuss the possibilities for legal action to seek redress for climate loss and damage, focusing on two types of action highlighted in Minister Regenvanu’s statement: action against states under international law, and action against fossil fuel companies under domestic law. After concluding that the issue of compensation for climate loss and damage is best addressed at the multilateral level, we offer proposals on how the two processes of litigation and negotiation could interact with each other and inspire more far-reaching action to address loss and damage from climate change.
