    In March, the global community agreed to establish a legally binding treaty to end plastic pollution. To deliver on this goal, the treaty needs to cover all issues of plastics chemicals as an inseparable part of the problem.

    Plastics are complex materials consisting of chemical mixtures, including polymers, additives, residual monomers and processing aids, and non-intentionally added substances. Such mixtures release across the plastics life cycle, from feedstock extraction, production, and use, to reuse, recycling, and disposal; they also recombine along complex, unplanned pathways. As a result, humans and environments are ubiquitously exposed to plastics chemicals, often with serious consequences.

    Out of more than 10,000 known plastics chemicals, at least 2,400 are classified as toxic, such as many phthalates and brominated flame retardants. Documented health effects span generations and include premature births, low birth weight, obesity, diabetes, cardiovascular disease, endometriosis, infertility, and cancers. In the United States alone, associated costs of endocrine-disrupting chemicals amount to USD$300 billion/year. The total burden on community, ecosystem health, and biodiversity is far greater.

    Even with material recycling, plastics chemicals ultimately proliferate in the ecosystem, whether as emissions or by entering new products, exposing waste-laborers, consumers, and frontline communities to new chemical cocktails. An effective, fair, and safe circular economy can only be achieved by phasing out toxic chemicals from plastic production. 

    As negotiations for a global treaty begin, plastics chemicals need to be front and center. However, preparatory meeting documents focus on downstream plastic waste and work from a narrow definition of chemicals as hazardous additives. To enable the treaty to fully address plastics’ ecological, health, and environmental justice problems, it is essential to redefine plastics as complex chemical mixtures and to integrate chemical issues across the life cycle within the scope and core obligations of the legal instrument.
