On 22 July 2025, IARC released a report highlighting the opportunities to align climate mitigation actions with primary cancer prevention in Europe. Based on the 4th Edition of the European Code Against Cancer and the UN’s 2030 Climate Solutions Roadmap, the analysis outlines joint interventions that can lower cancer risk while benefiting the environment. There are many known cancer-causing agents or unhealthy lifestyle behaviours that might be altered by climate change. Specifically, the authors focus on: promoting healthy diets, reducing air pollution, and encouraging active lifestyles. Policymakers are urged to adopt integrated public campaigns and cross‑sectoral policies.
