Climate change is reshaping every part of society -- and criminal justice is no exception. This groundbreaking book examines how the climate crisis is transforming policing, courts, corrections and communities, from disaster responses and harm prevention to criminalisation of protest and prison design. Blending international examples with practical insights, it reveals the urgent dilemmas and opportunities facing criminal justice institutions as they navigate ecological upheaval, shifting priorities and political pressures. It is essential reading for practitioners, policy makers and scholars seeking to understand and act on the challenges of delivering justice in a rapidly heating world.
