The Minderoo-Monaco Commission on Plastics and Human Health finds that plastics are both a boon to humanity and a stealth threat to human and planetary health. Plastics convey enormous benefits, but current linear patterns of plastic production, use and disposal with little attention to sustainable design or safe materials and a near absence of recovery, reuse and recycling are responsible for grave harms to health, widespread environmental damage, great economic costs, and deep societal injustices. These harms are rapidly worsening.
“These findings put us on an unequivocal path to demand the banning or severely restricting of unnecessary, avoidable, and problematic plastic items, many of which contain hazardous chemicals with links to horrific harm to people and the planet. In 2015, 4 per cent of fossil fuel was used to make plastic and, by 2050, this is predicted to increase to 20 per cent. Even worse, as fossil fuel production continues to soar, so will the profound impacts we already see increase even more.”

Global intervention against the plastic crisis is needed now, because the costs of failure to act will be immense.
While there remain gaps in knowledge about plastics’ harms and uncertainties about their full magnitude, the evidence available today demonstrates unequivocally that these impacts are great and that they will increase in severity in the absence of urgent and effective intervention at global scale. Manufacture and use of essential plastics may continue. But reckless increases in plastic production, and especially increases in the manufacture of an ever-increasing array of unnecessary single-use plastic products, need to be curbed.
Current practices for the production, use and disposal of plastics cause great harms to human health and the global environment, and they are not sustainable. These harms arise at every stage across the plastic life cycle. They include human health impacts such as developmental neurotoxicity, endocrine disruption and carcinogenesis. In the ocean, plastics’ harms extend far beyond the visible and well-recognized damages of beach litter, contaminated mid-ocean gyres, and physical injury to marine species and include extensive injury to marine ecosystems.
The thousands of chemicals in plastics – monomers, additives, processing agents, and non-intentionally added substances (NIAS) – are responsible for many of plastics’ harms to human and planetary health. These chemicals leach out of plastics, enter the environment, cause pollution, and result in human exposure. In the environment and in the bodies of living organisms, many plastic chemicals can undergo chemical transformation to form breakdown products and metabolites, some of which are highly toxic and contribute further to plastics’ harms.
The economic costs of plastics’ harms to human health and the global environment are very high. We estimate that in 2015 the health-related costs of plastic production exceeded $250 billion (2015 Int$) globally, and that in the US alone the health costs of disease, disability and premature death caused by three plastic chemicals alone (PBDE, BPA and DEHP) exceeded $920 billion (2015 Int$). The cost of greenhouse gas (GHG) emissions from plastic cause economic harms that we value at $341 billion (2015 Int$) annually.
The health, environmental and economic harms caused by plastics disproportionately affect vulnerable and at-risk populations – the poor, people of colour, and Indigenous populations as well as fossil fuel extraction workers; plastic production workers; informal waste and recovery workers; persons living in communities adjacent to fossil fuel extraction, plastic production, and plastic waste facilities; and children. These disparate harms are seen in countries at every level of income, including high-income countries.
