This chapter delves into activists’ vital call to action to criminalize harm to the planet as ecocide, or extensive damage, destruction, or loss of ecosystems within a territory to such an extent that the peaceful enjoyment of the inhabitants is severely diminished. Beginning with an exploration of major existing international laws that have criminalized significant environmental harms, the chapter elucidates the rationale behind the urgent demand to criminalize climate change. It highlights the interconnectedness of climate change and social disparities, shedding light on how these disparities magnify the vulnerabilities of marginalized populations who fall victim to ecocide. However, due to the inherent limitations of criminal legal systems in addressing the underlying causes of environmental harm, the chapter emphasizes that advocating for criminalization does not imply endorsing punitive measures. Rather, it acknowledges the narrow scope of criminal legal systems, at both domestic and international levels, and instead advocates for restorative and transformative justice responses. By acknowledging the intricate links between climate change, crime, and violence, and by espousing an approach that seeks to restore justice and transform social structures, the chapter endeavors to tackle a small part of the larger issue of climate change, the most pressing social problem of our time.
