The climate crisis is a health crisis; it demands the urgent attention and action of healthcare professionals and organisations. In this issue of the BJPsych Bulletin, we consider what the destructive effects of the climate and ecological crisis entail for the mental health of populations, and what the response of psychiatrists, both individual and collective, must be. We also highlight the opportunities and benefits a more sustainable and preventative approach could offer individuals, communities and the planet.
Keywords: Sustainability; climate crisis; climate emergency; mental health; psychiatrists.
