Plastic waste is piling up at a daunting pace around the world. The World Bank estimates that every person on the planet generates an average of 1.6 pounds (0.74 kilograms) of plastic waste daily.To curb this flow, 175 nations are negotiating a binding international treaty on plastic pollution, with a completion target of late 2024. In July 2024, the Biden administration released the first U.S. plan for addressing this problem.The new U.S. strategy covers five areas: plastic production, product design, waste generation, waste management, and plastic capture and removal. It also list actions that federal agencies and departments are currently pursuing.I study environmental law, including efforts to reduce plastic pollution. As the worlds largest economy, the U.S. is a critical player in this effort. Based on my research, here are three proposals in the U.S. plan that I believe are important and one omission that I view as a major gap. A federal standard for measuring microplasticsStudies have detected tiny plastic fragments, known as microplastics, in settings that include the atmosphere, drinking water sources, wild animals, and human food chains.While scientists have found that wildlife, such as seabirds, can be harmed by consuming plastic, the effects on human health are less clear. Unlike other pollutants, microplastics have different effects depending on their size, their shape, and where they are found, such as in food, air, or water. And humans can be exposed to them via many different pathways, including inhalation, ingestion, and touch.There is no federal standard for measuring microplastics in various media, such as water and soil, so studies lack standardized definitions, methods, and reporting techniques. In 2023, California launched a microplastic monitoring program, which includes developing a standardized method for measuring microplastics in drinking water.The Biden administrations plan calls for developing standardized methods for collecting, quantifying, and characterizing microplastics and nanoplastics, which are even smaller. This will help scientists generate consistent data that regulators can use to set limits on microplastics in food, water, and air.Extended producer responsibilityAll plastics contain chemicals that add properties such as strength, softness, color, and fire resistance. A subset of these chemicals, including bisphenols and phthalates, have been linked to adverse health effects that include fetal abnormalities, reproductive health problems, and cancer.Some scientists argue that certain types of plastic waste with particularly harmful ingredients or properties, including PVC, polystyrene, polyurethane and polycarbonate, should be classified as hazardous waste. Currently, the U.S., Europe, Australia, and Japan consider items made from these plastics as solid waste and treat them in the same way as kitchen food scraps or used office paper.The fact that only about 5% of U.S. plastic waste is currently recycled, while 9% is incinerated and 86% is buried in landfills, has sparked calls for assigning some responsibility to plastic producers.Extended producer responsibility laws, which exist for other products such as paint and electronics, make producers responsible for collecting and disposing of their products or paying part of the costs to manage these wastes. Such requirements give producers incentives to create more environmentally friendly products and support recycling.As of mid-2024, California, Colorado, Maine and Oregon have adopted extended producer responsibility laws for plastic waste, and about a dozen other states are considering similar measures. Studies show that when such policies are adopted, recycling rates increase.The Biden administration plan calls for launching a national extended producer responsibility initiative that would allow state, local, and tribal governments to develop their own approaches while offering a vision for a harmonized national system and goals for plastic waste management. Support at the federal level could help more jurisdictions enact rules that require producers to help manage these wastes.Banning single-use plasticsBans on plastic items are a tool to reduce waste generation. Most of these measures apply to items that are used once and discarded, such as shopping bags, food wrappers, and plastic bottles. Items like these are the most common plastics in the environment.The U.S. plan calls for developing strategies to replace, reduce, and phase out unnecessary use and purchase of plastic products by the Federal Government, including an end to the purchase of single-use plastic items by 2035. Although this action applies only to use by federal agencies, the U.S. government is the largest single purchaser of goods and services in the world, so this step can send a powerful signal in favor of alternative products.Whats missing: A cap on plastic productionCurrent projections suggest that global plastic production will double by 2040, with an accompanying surge in plastic waste. In response, 66 countries have formed the High Ambition Coalition, cochaired by Norway and Rwanda, to support stringent provisions in the global plastics treaty. One of their central goals is limiting global plastic production.Early in 2024, several nations participating in the treaty negotiations proposed to cut world plastic production 40% below 2025 levels by 2040. This concept is still under discussion.Plastic manufacturers and companies reliant on plastic argue that a production cap would drive up the costs of all plastics. Instead, groups like the World Plastics Council are calling for steps that would reduce plastic waste generation, such as using resins with more recycled content and increasing recycling rates.Given the size and economic influence of the U.S. plastics industry, I believe it is unlikely that the U.S. will join the High Ambition Coalition countries during the final session of treaty negotiations. However, Congress could still consider domestic proposals, such as the Break Free From Plastic Pollution Act, which includes a temporary pause on permits for new plastic production facilities, as a means of capping production.
