My research focuses on the protection of climate vulnerable states and communities under international law. It analyses key avenues within international environmental law, state responsibility and human rights law, capable of providing these states and communities with an effective remedy for losses incurred as a result of adverse climate change impacts. It is driven by a desire to contribute to the growing climate justice literature from an international legal perspective, taking into account the access to justice challenges which exist in practice. It includes a regional case study of the South Pacific, examining climate justice and the enforceability of international mechanisms at a more grassroots level.
