Experts call for mental-health metrics to be woven into global environmental treaties

Leading experts in psychology, psychiatry and public health contend that worldwide environmental accords have largely ignored the mental-health repercussions of climate change, biodiversity loss and pollution. They explain that exposure to neurotoxic chemicals, ecosystem degradation and climate-driven disasters can impair child development, elevate anxiety and depression, and raise suicide rates, especially among vulnerable groups.

Existing treaties treat mental health as a separate domain, lacking reporting, financing or accountability mechanisms tied to environmental outcomes. The authors propose a tiered policy model that aligns chemicals and hazardous-waste conventions, Rio-based climate and biodiversity agreements, and atmospheric protocols with mental-health metrics and financing incentives. Embedding shared indicators and accountability into current governance could turn environmental policies into upstream interventions that prevent mental-health conditions. The approach calls for coordinated action across UN frameworks, the WHO mental-health action plan and the Sustainable Development Goals.
