Plastic waste is piling up at a frightening tempo around the globe. The World Financial institution estimates that each individual on the planet generates a median of 1.6 kilos (0.74 kilograms) of plastic waste every day.
To curb this movement, 175 nations are negotiating a binding worldwide treaty on plastic air pollution, with a completion goal of late 2024. In July 2024, the Biden administration launched the first U.S. plan for addressing this drawback.

The brand new U.S. technique covers 5 areas: plastic manufacturing, product design, waste technology, waste administration and plastic seize and removing. It additionally lists actions that federal businesses and departments are at the moment pursuing.
I examine environmental regulation, together with efforts to cut back plastic air pollution. Because the world’s largest financial system, the U.S. is a crucial participant on this effort. Based mostly on my analysis, listed below are three proposals within the U.S. plan that I imagine are necessary and one omission that I view as a significant hole.
A federal customary for measuring microplastics
Research have detected tiny plastic fragments, often called microplastics, in settings that embody the ambiance, ingesting water sources, wild animals and human meals chains.
Whereas scientists have discovered that wildlife, akin to seabirds, may be harmed by consuming plastic, the results on human well being are much less clear. Not like different pollution, microplastics have totally different results relying on their dimension, their form and the place they’re discovered, akin to in meals, air or water. And people may be uncovered to them by way of many various pathways, together with inhalation, ingestion and contact.
There isn’t any federal customary for measuring microplastics in varied media, akin to water and soil, so research lack standardized definitions, strategies and reporting methods. In 2023, California launched a microplastic monitoring program, which incorporates growing a standardized methodology for measuring microplastics in ingesting water.
The Biden administration’s plan requires growing standardized strategies for gathering, quantifying and characterizing microplastics and nanoplastics, that are even smaller. It will assist scientists generate constant knowledge that regulators can use to set limits on microplastics in meals, water and air.
Prolonged producer accountability
All plastics include chemical substances that add properties akin to energy, softness, colour and fireplace resistance. A subset of those chemical substances, together with bisphenols and phthalates, have been linked to opposed well being results that embody fetal abnormalities, reproductive well being issues and most cancers.
Some scientists argue that sure sorts of plastic waste with notably dangerous substances or properties, together with PVC, polystyrene, polyurethane and polycarbonate, needs to be labeled as hazardous waste. Presently, the U.S., Europe, Australia and Japan contemplate objects produced from these plastics as stable waste and deal with them in the identical method as kitchen meals scraps or used workplace paper.
The truth that solely about 5% of U.S. plastic waste is at the moment recycled, whereas 9% is incinerated and 86% is buried in landfills, has sparked requires assigning some accountability to plastic producers.
Prolonged producer accountability legal guidelines, which exist for different merchandise akin to paint and electronics, make producers accountable for gathering and disposing of their merchandise or paying a part of the prices to handle these wastes. Such necessities give producers incentives to create extra environmentally pleasant merchandise and help recycling.
As of mid-2024, California, Colorado, Maine and Oregon have adopted prolonged producer accountability legal guidelines for plastic waste, and a few dozen different states are contemplating related measures. Research present that when such insurance policies are adopted, recycling charges enhance.
The Biden administration plan requires launching a nationwide prolonged producer accountability initiative that might enable state, native and tribal governments to develop their very own approaches whereas providing a imaginative and prescient for a harmonized nationwide system and objectives for plastic waste administration. Assist on the federal degree may assist extra jurisdictions enact guidelines that require producers to assist handle these wastes.
Banning single-use plastics
Bans on plastic objects are a software to cut back waste technology. Most of those measures apply to objects which might be used as soon as and discarded, akin to purchasing baggage, meals wrappers and plastic bottles. Objects like these are the most typical plastics within the surroundings.
The U.S. plan requires growing methods to “replace, reduce, and phase out unnecessary use and purchase of plastic products by the Federal Government,” together with an finish to the acquisition of single-use plastic objects by 2035. Though this motion applies solely to make use of by federal businesses, the U.S. authorities is the largest single purchaser of products and companies on the earth, so this step can ship a strong sign in favor of different merchandise.
Capping plastic manufacturing
Present projections recommend that world plastic manufacturing will double by 2040, with an accompanying surge in plastic waste. In response, 66 nations have fashioned the Excessive Ambition Coalition, co-chaired by Norway and Rwanda, to help stringent provisions within the world plastics treaty. Certainly one of their central objectives is limiting world plastic manufacturing.
Early in 2024, a number of nations taking part within the treaty negotiations proposed to chop world plastic manufacturing 40% beneath 2025 ranges by 2040. This idea continues to be below dialogue.
Plastic producers and corporations reliant on plastic argue {that a} manufacturing cap would drive up the prices of all plastics. As an alternative, teams like the World Plastics Council are calling for steps that would scale back plastic waste technology, akin to utilizing resins with extra recycled content material and growing recycling charges.
By way of mid-2024, the U.S. had not endorsed a cap on plastic manufacturing. Nonetheless, in August, press reviews said that the Biden administration was altering its place and will help limits, together with creating a world record of goal chemical substances to limit.
This can be a main change that I anticipate may transfer extra nations to help limits on new plastic manufacturing. Particulars are prone to emerge as the ultimate spherical of negotiations, scheduled for November 2024 in Busan, South Korea, approaches. The plastics business strongly opposes limiting manufacturing, and Congress must ratify a world treaty to make its provisions binding on the U.S. However U.S. help may enhance the probabilities of capping the ever-increasing movement of plastic into the world financial system.
