Harm, Impact, and Interventions

The Lancet Countdown on Health and Plastics

Tracking the harms of plastics to human health across the plastics life cycle

An independent, health-focused global monitoring system — co-led by Boston College & Heidelberg University

Health Costs US$1.5T annual health-related economic losses from plastics

Plastics Production 475 Mt plastic produced in 2022 — up from 2 Mt in 1950

Waste 8,000 Mt plastic waste currently polluting the planet

Recycling <10% of plastic waste is ever recycled

Domains 1 & 2 — Emissions and Exposures Across the Plastic Lifecycle

Fossil Extraction

Climate change
Biodiversity loss
Environmental degradation

Production

Toxic chemicals
Particulate matter

Consumer Use

Toxic chemical leaching
Plastics in food, water, air & humans

Disposal & Waste Management

Waste & disease vectors
Toxic chemicals
Air pollution via combustion

End of Life & Degradation

Ecosystem losses
Plastics in environments
Loss of cultural values & income

Domain 3: health impacts (including economic) +

Plastic exposures across all lifecycle stages converge to cause measurable, often severe health outcomes. Impacts fall disproportionately on low-income communities, workers, and children in the Global South.

Cancer

Vinyl chloride, benzene, styrene, and other plastic-related chemicals are established carcinogens linked to leukemia, lymphoma, and liver cancer.

Endocrine Disruption

Bisphenols, phthalates, and PFAS mimic or block hormones, affecting reproduction, fetal development, thyroid function, and metabolism.

Neurodevelopment

Lead, cadmium, and phthalates in plastics impair brain development in children, reducing IQ and raising risk of ADHD and autism spectrum disorders.

Cardiovascular Disease

Microplastics found inside arterial plaques are associated with increased risk of heart attack and stroke. Air pollution from plastic combustion further strains the heart.

Respiratory Disease

PM2.5 and volatile chemicals from plastic production and incineration cause asthma, COPD, and lung cancer in workers and surrounding communities.

Economic Losses

Health-related losses exceed US$1.5 trillion annually — costs borne primarily by the communities least responsible for plastic production.

Domain 4: interventions & engagement — measures at international, national, regional, local, and individual levels +

Plastics' harms are not inevitable. Like lead and air pollution, they can be reduced cost-effectively through evidence-based policies tracked and implemented at every level of governance.

International

UN Global Plastics Treaty negotiations; multilateral agreements targeting plastic production, trade, and chemical restrictions across borders.

National

National bans on single-use plastics; chemical safety regulations; mandatory reporting requirements for plastic production and emissions.

Regional

Extended producer responsibility programs; regional recycling infrastructure investment; waste-to-energy with enforceable health safeguards.

Local

Improved waste collection and management; monitoring of plastic pollution hotspots; community education and health surveillance programs.

Individual

Consumer choices to reduce single-use plastic; civic engagement and advocacy; supporting policy reform through collective action and public pressure.
