Plastic Health Risks Could Double by 2040

Adverse health effects stemming from the global plastics system are projected to more than double by 2040, relative to 2016 figures, if current trajectories persist. This projection is based on a new lifecycle assessment study, which also suggests that worldwide plastic production might not reach its peak until after the year 2100.

The research, published in The Lancet Planetary Health, quantifies health impacts in terms of disability-adjusted life-years attributed to greenhouse gases, air pollutants, and toxic chemicals released throughout the plastics lifecycle. Key contributors to these health burdens include primary plastics production and open burning of waste.

Researchers emphasize that a globally coordinated policy addressing upstream effects through a full lifecycle approach is crucial. They recommend a significant reduction in the production of virgin plastics for non-essential applications. The study also noted that the non-disclosure of chemical compositions hinders comprehensive lifecycle assessments and effective policy formulation.

Over 175 countries are currently engaged in negotiations for a Global Plastics Treaty, aiming to establish international regulations. The findings underscore the urgent need for policymakers to better regulate and reduce the production of new plastics to protect human health and the environment.
