This section explores how climate change is reshaping crime and harm by influencing human behaviour and creating new, or exacerbating existing vulnerabilities. It examines the evolving landscape of environmental and climate-related crimes, as well as the interconnections between them, emphasizing the need to reconceptualise the notion of a crime scene and develop effective policing strategies for identifying, investigating, and addressing these complex issues. This section also draws on insights from the ecocide movement’s global advocacy, which builds momentum around critical issues while promoting a comprehensive legal framework. The chapter concludes by highlighting how emerging scholarly literature on climate crimes, climate offenders, climate litigation signals a transformative shift in the landscape of crimes and harms that increasingly demands an adequate police response.
