This article argues that ecocide should be considered an international crime because of its severity, magnitude, potentially lasting effect, and the effect it has on many aspects of lives of different species. Corporations are indivisibly linked with ecocide as they recklessly seek profits. Even though corporations do not set out to commit acts of ecocide, i.e. they lack intent, they should still be held accountable. International criminal law can be used as a tool to deal with corporate ecocide. Adopting ecocide as an international crime can affect corporate accountability as it offers the opportunity to spark debate on the possibilities to tackle these issues in a consistent and effective way.
