Using the case of Vanuatu, which has been severely impacted by climate change-related storms, this paper highlights the need for an international legal framework to hold perpetrators of large-scale environmental harm accountable. Vanuatu’s advocacy, alongside the Stop Ecocide campaign, seeks to address the environmental degradation caused by human actions that result in significant loss of life and cultural destabilization, akin to the impact of genocide. The paper contends that categorizing ecocide as an international crime is necessary to uphold justice for affected nations and recommends an amendment to the Rome Statute to enable the ICC to prosecute ecocide offenses. The author concludes that international recognition of the crime of ecocide is necessary to mitigate environmental destruction and protect vulnerable populations.
